I just recently swapped out my transmission over to a 5 speed and had to rewire the entire harness and it will not crank over after re wire. I'm not sure if i wired it wrong or not but if someone could find me a decent wire diagram for it i should be fine. Everything works I.E headlights, wipers all dash lights except check engine light as well.

Btw it is the 420a engine.

Just buy a 420a 5 speed harness and be done.

Otherwise buy a 420a FSM and use the wiring diagram in that. If you are too cheap to pay for a FSM, there are places to get them, torrent sites, etc but they generally are not complete.

Seriously just go to ebay, get the FSM, and while your there look for a n/t 5speed harness, or call S&M autoparts and get a quote for a harness. They sent me an interior harness for 45$ shipped.

If all else falls i was just going to go to a junkyard tomorrow and take out a harness if i get lucky and find one. I need a new computer too because the connectors will not remove from the computer. Findind a matching 95 one will be hard. and not to sound to much like a noob but what is a fsm... :/

Whats up guys. I have a slight problem. I was cruising in town a couple of nights ago, and all of a sudden my car DIED. I was going about 30 mph, and the car completely shut off. The good thing i wasnt a public road. I stopped, and tried to start the car, and all i did was turn over. The engine just wouldnt start. So a cop came (the lady whos house i was in front of called the cops on me) to my suprise he was very chill. I tried starting the car and it was so close to starting but no cigar. Had to call a tow truck and crap. And this morning i tried starting it, and right when i press the clutch and start the key the car just dies. Doesnt make any noise what so ever. Im going to jump it once my buddy comes. Any suggestion?! Please help.
P.S sorry about the long post.

90% of the time that would be timing belt failure. Pull cam cover and verify belt is good and timing marks are lined up

Thank you very much good sir

Just got done rebuilding motor in this 97 eclipse gst. Now i cant get it to start! I have spark have fuel and all of my timing marks line up perfect! Made sure cylinder number one was tdc first. Ive read about cas could be off? We had the head apart facing the valve. How can i check the cas and what else could it be! Thanks

Check fuses, make sure you have everything connected, what is it doing, does it even crank double check everything. Could be something simple.

Sorry i didnt mention that it cranks fine . It trys to fire but i would get some backfires and like choking almost like it tried to start and didnt

With the mechanical timing at #1 TDC (all marks lined up to their respective marks) the CAS should be lined up with it's "timing" marks. Take it off and you will see a notch on the paddle and a dot on the body of the CAS. Those are the timing marks. This is assuming a 1g CAS is installed.

Also make sure that your plugs wires are in proper order. With a 95 ECU in the 97 if he has link, 1 and 4 get's switched with 2 and 3 at the coil pack.

okay so the other day when going through the bk drive though when i shut my car off to order it wouldnt start back up again. so i checked for spark, no spark at first so why not try the cheap route and get new plugs. so i did still no spark, plugged in new coil, no spark still so i decided to look at my ecu.. blown.. sooo i got to a guy and got a new one just plugged it in along with a new isc motor and it still wont start but now i have spark and when i checked in the bk parking lot i had fuel.. well at least the fuel pump was running. i dont know what to do what could be causing it not to start?

Everything is bone stock in this 97 right down to exhaust and air filter! So its 2g everything so can those be off as well?

any reciprocating combustion type motor needs these things to run.

Fuel
Air
Spark(ignition source)
Compression
And it all has to happen at the correct time
A path for your exhaust gases

Sooo....Pull your plugs. Are they wet and smell Like gas? If so, you are getting fuel. If not, check your pump, injectors, and fuel pressure. Pumps not getting signal to run, it's bad, or the filter is plugged. Injectors are not pulsing(passing fuel)

Once your plugs are out, do a compression test if you feel you need to. I would, just because I'm there. Could have jumped time and this could point you that way.

Some would flame me for this but it works, Install a know good spark plug into each wire, one at a time. Lay the plug on the engine and crank it. Do they all have a good spark?

Air is most likely not your problem unless you air filter completely collapsed.

Timing. Set your crank at tdc, check your cam gear marks. Stick a long screw driver in the hole of #1, move the crank a little back and forth. When the screw driver is as high as it will go does the crank marks show tdc. I hope it does, that would be really bad.

Spark timing check depends on your car. I would refer you to a manual and suggest checking the ecu. You might check to make sure you put the right spark plug wires on the right plugs. Seen that many times.

Exhaust path is probably fine, unless somebody stuck a potato in you exhaust pipe.

Happy testing!

P.S.- There's a pretty good no start diagnostic thread on here somewhere too.

on the ecu how could i have plugged in the wrong things arent they all different size plugs? i checked the spark its good i know my fuel pump is running what is a good way to check if the injectors are pulsing?

do you have a tuning devicehttp://www.youtube.com/watch?v=pCGmI6rDptU

I meant spark plug wires not ecu wires, my bad. I fixed it in the post above. By checking ecu I meant to actually test the output to the injectors. I'm not certain about a 1g, but a 2g you can test the pins on the ecu for volts out. You would have to do a search to find out how and what voltage your looking for.

You can actually hear and feel the injectors "clicking" while cranking. You would at least know that's working.

how do i check for injector pulse?

Shoot, same problem here. I get spark, fuel to the rail and injectors 1 and 2, but not 3 and 4. Anyone that knows what the problem is please help us out thanks.

i also have the same problem what did you do to fix it?

a noid light is the easiest way. unplug an injector and plug the noid light into the injector connector and crank the engine over if the light pulses then the its getting a signal

Get a noid test tester that has the extension so you can mount the noid light on the wipers.
Then you can see the light when cranking the engine from the driver's seat.

If the ECU does not detect a ignition pulse (pin109) it will shut down the injectors and then the fuel pump (via MPI).

okay so i checked i have no injector pulse. what could cause that a bad cas? but i still have spark

How is your ecu, and the wiring?
