If the front end is tight, I would go with the half shafts. If the inner cv is worn or binding, it will cause the whole front end to 'wobble' or shift side to side. Under acceleration, worn or binding cv's will bind up inside the axle cup and not be able to slide while turning. The axle...

The first test I would do requires only a simple test light. Connect the clamp to the neg side of the battery and touch the probe to the main power wire at the starter. If it lights, you have power to the starter. Next, as long as there is power at the big wire to the starter, put the tester to...

Those bolts go through the engine mount. You will need to jack the engine up a little and then take the mount out with the bolts still in it. If you pull the bracket back towards the frame rail, with a bunch of twisting and turning you will get it out. You may have to go up and down with the...

Dude, if you have a 420a and the crank pulley comes right off you should be buying a replacement !!! However, your profile suggests you are on a 4g63 The balancer on a 420a has NO KEYWAY and should be press-fit. I have seen 'loose fitting' balancers shear crank bolts and spin t-belts when the...

If pin 2 is showing constant ground without blinking, I would say that the ecu and wiring to the ICM is ok. I believe the CAS output would be suspect now. The CKP is more of a TDC sensor, as it outputs once per revolution and doesn't have any waveform variation. This lets the ecu know where TDC...

Don't forget to check for leaks on the other side of the throttle plate as well. If you sucked in intake gasket, the ecu will think the ISC can't control the idle correctly. Are you showing good vacuum at idle? (In between surges, that is !!)

Using the correct puller to remove the harmonic balancer makes the job easy and prevent any broken parts... OTC makes this tool and it can be ordered from Advance auto parts or other parts stores I am sure. Part #OTC 6667. It is designed just for the 420a and a few other Mopar balancers Here...

Recheck the timing marks... 4" vacuum and very slow accel. sounds like you have one or both of the cams off by a tooth or 2. If the valves are opening too early or too late, the engine will not make vacuum. Start with the basics once you verify timing marks. Vac. leaks at the intake or...

Wow, this thread seems to be going 'broken arrow' here. First, WOT pulls are perfectly fine, if the tune is set up correctly... There is no need to work the throttle while building boost pressure unless you have a 2wd and don't like wheel spin. As for the OP concern. 16 psi is pushing the...

I'm a little lost. A couple posts ago you said the car was at a shop, yet you are still asking for someone to come and look at it..... Have you bothered to check wiring from the ecu to the ICM? If the ecu lost an internal ground, you won't get spark on one of the coils. With key on, check pin...

Thanks Justin, It makes sense now, just doesn't REALLY feel like creep because it doesn't build pressure, then go higher. It is more like all at once. Cat. converter, here I come !

I am using source pressure directly off of the turbo.... If I have a boost leak at the intake manifold, this would cause the system to create too much pressure? Doesn't seem correct. I took pretty much all the variables out of the equation by taking the shortest route possible which is about...

I have a 6 bolt with ported 2g exhaust mani and a ported 2g o2 housing then going to straight 3" exhaust. FMIC (ebay style) and a fresh rebuilt small 16g. We put on a manual boost controller that was on the lowest setting. When we drove it, it overboosted, like 23 psi!! It only seems like it...

Update time!!! 12/18/11Tried to put a link to this spot, but instead I used a bunch of red typing to make it easier to FIND![/SIZE] After almost 2 months of working on the car, saving money, buying parts and trying to run a business... We are just hours away from hearing the Talon run again ...

This question may have been answered a Gazillion times here, but dam'd if I can find the answer anywhere. I just picked up a palm IIIx. There are 3 wires on the cable and I can't seem to find the pin locations for install. When I search the forums I just get data communication threads. I...

Code 11 or 13 or P0700 is an ECM code stating there are transmission codes stored Code 24 or P1784 is for the L/R pressure switch sense circuit. Code 47 or P1776 is for the solenoid switch latched in L/R-This can sometimes be caused by a mis-adjusted shifter cable/Trans. range switch...

The best idea to find the cause would be to get yourself some engine oil black light tracer dye. Depending on how long it takes it to make a noticeable leak, run/drive it for a little while, then you will be able to follow the trace from the source. Most parts stores have the dye and a fairly...

Good find man ! Thankfully you didn't start tearing all the harness apart.. Time & electrical tape saved-priceless

Only asked about the re pin to make sure a wire or 2 didn't get put in the wrong place.

Did you have the CAS unplugged when checking voltage at pin 88? The voltage is supplied by the ecu, throught a resistor. If there is higher voltage at the ecu you could have another resistance source in the wiring to the cas. There is nothing else on that wire and no inline connectors. I...

Just a thought about this. The ECU would turn the fans on if it sees an overheating issue. Is the ECT plugged in? When you spin the CAS, the ecu will react as if the engine is running or at least trying to run, and if the coolant temp. is registering high enough, it could turn the fans on to...

The cross over pipe on a 90 doesn't have the 2 extra lines because the oil filter adapter was only air cooled. I believe the other line you are looking for comes off the water outlet housing, which on a 7 bolt goes down to the cooler and on a 6 bolt goes to the turbo. Not sure why you need to...

You marked this as resolved..... Yet you didn't post what you did to resolve it. Could you explain what the fix was?

That is fuse #6 which feeds the ignition switch. The other components on that circuit aren't really effected when starting (door locks, mirrors, wipers ect..) Being that it is a 30 amp circuit, a DVOM would be useless here. The easiest test is going to cost you another fuse, but it is the place...

I am assuming it is a pink 30A fuse that is giving you problems? Which fuse number is it? Looking at the fuse box #4 is in the top right corner then the row of fuses goes like this #5-green, #6 pink, #7 pink, #8 yellow, #9 pink You may not have all of them.... Let me know which one and we...

Have you tried leaving a few threads exposed at the upper end of the sensor? This should be enough to allow for a good ground. You may want to test ground it with a piece of wire to make sure it isn't already grounded and you have another problem. Normally, teflon tape will allow the threads to...

Amy comments on the copper gaskets?

Sounds like you could have an injector leaking, filling one of the cylinders with fuel. How long to it have to sit before this happens? 4 hours, 6 hours, longer??

Well I just noticed that ffwd lists their gasket as 61mm hole, but I noticed no one mentioned the copper gasket option yet. SEC lists what I believe to be the same copper gasket (as it seems they make most of the gaskets for ffwd..) however it doesn't list what the hole size is. I was going to...

Maybe I haven't looked hard enough or my math skills aren't what they used to be but I have a ported 2g exhaust mani that I purchased and the outlet is ported bigger than stock. I know everyone says the 7 cm gasket, but measuring it, I only get about 58ish mm. Is the 7 cm the only choice over...

Well, after a busy week and an ugly, snowy, tree snapping, power line tearing weekend, I have no power at the shop and they don't expect to have me back to making money until Friday..... Therefore, I brought my son in to the shop today and we shoveled the parking lot. After finishing that up, we...

Any news?

Not sure if you have this fixed yet or not, I have been busy and got knocked down by last weekends snow storm.... If you are still hanging, here are the tests you should be doing: 1. Unplug A106 connector at the ecu and unplug the coil pack conn. 2. Set your DVOM to ohms (100 or so scale...

In the vid. it sounds like the starter. If your battery voltage is good, try this: Connect the neg lead of your volt meter to ground and check the power to the positive cable at the starter. Make sure it shows around battery voltage. Next, touch the pos. lead to the small signal wire at the...

I am assuming that you mean spark plug WIRE resistance no?The rule of thumb is 10-15k ohm/foot

Sounding like an ignition switch/lock cylinder issue here. If the switch is shorting internally it could cause the starter to 'run on' if it doesn't cause a big enough short to ground to blow that fuse again.

Right on DSM1G90, the EGR system recirculates exhaust gases back into the cylinder throught the intake to lower internal cylinder temps. NOx is a byproduct of combustion that occurs above 2500 degrees F. The EGR normally will purge on cruise and deceleration, allowing cylinder temp. reduction...

My first question would be this... Is the timing belt still on and intact? If the belt broke or lost a couple teeth and you aren't spinning everything on proper timing, than a compression test would prove almost useless. If all is well with the belt, the compression test will show which...

After letting this car sit for almost 6 years, I have decided to rebuild it and make some mild/moderate upgrades. I wanted to share this rebuild with everyone and will try to post updates/ improvements as I go. Let me start with a little background. I have been an auto tech. for over 19 years...

The wires from ECU to coil pack showed no resistance? That would be a problem. You need to test for resistance between them. I can't remember for sure but the 420a didn't use a power transistor if I recall, so it would seem that you may have overlooked something. If you have a long enough piece...

If you are getting spark at all, you should be able to rule out the CKP and CAS. The coil recieves power from the ASD relay and the pcm grounds the B/L wire for one side of the coil pack and B/R wire for the other. You can test this by using a test light connected to power and probe one of...

The PS pressure switch causes the ecu to bump the idle speed slightly when it recieves steering input. Mine was unhooked for a while with me even knowing it. I don't see a problem, but you may want to kick your idle up alittle to make up for it if it drops too low when not rolling and turning.

LMAO, here is the schematic for the rear wiper system if it helps

Well... no fuel is less harmful than fuel with no spark but, I wouldn't recommend doing it for too long. I saw a few sets in the marketplace just yesterday. The sooner the better, at least that is the legal-eeze I use with my customers !!

by no ohms, you mean the tester displayed 'OL' ?? That would be an open circuit and a bad injector. The engine will run, but I would expect somewhat more than a 'small misfire'..... Measure twice, cut once.. retest that injector and if it still reads open, you should start shopping for an...

So you performed an ohm test from the supply to the load and it looks perfect... Problem is, it still has a problem. Here is a simple tool you can make to test a circuits ability to carry current and verify the circuit is performing as it should. The older these cars get, the more corroded and...

miguel, PM sent !Here is the '93 schematics

sigh... that feeds about every lighting system in the car it seemsLooking at systems that are powered up when you turn to key on:Cigarette lighter TCU Radio Cluster illumination *( could be idiot lights, it doesn't specify) Power mirror Hazard lightsAny of those been giving you...

Do you still have the cat. converter installed? Really wondering, now that you say you would lose boost pressure over 2500..... If it is plugged, you would have an issue along these lines.The engine codes can be tested with an analog volt meter. See attachment: Connect the volt meter...
