Starting issues - No / Doesn't / Won't Start - MERGED

[prodsm]

All "my car won't start" discussion threads are merged HERE. We've basically made it easier for those who insist upon not searching by grouping together all threads from those with similar issues so you can just scroll through and see some possible solutions. To search for info within this thread, use the "Search This Thread" feature in the black bar about 3" above what you're reading right now.

Could be anything from a loose battery terminal to internal engine damage, and literally everything in between which may involve the electrical, fuel, and ignition system...possibly even something that you screwed up while working on the car yourself. While it's unlikely we're going to diagnose and solve your problem over the internet, feel free to discuss any possible solutions.



I live in Canada and right now its not very warm out, about -30c
my car does not have a block heater too keep it warm.

I tryed to start my car this morning and it wouldent start, ive had this problem before but this time, the car doesnt crank at all it just makes a sound that sounds like an electric drill.

Whats wrong.

Thanks

I took the cas out of the head. I spun it by hand I hear no injectors firing. The key is on. I pull the plug about and stuck it to negative battery and spin cas, no spark.
Does this mean cas is bad and is this my problem?
How can car semi start with bad cas and starting fluid?

Check and make sure you have the correct harness plugged into the coils. The ac plug fits it too.

There are no other plugs down there except a 1pin plug.

Both of mine had another triangular plug that will plug right into the coils.

 

[SaulHudson]

So according to aem instruction you wire map into same pins for pwr and ground of tps. The instruction fails to mention this. Any ways I now have my tps wired properly. However it is no different.

Triple check your timing.

Triple check your timing.

All marks line up.

This sounds like a no spark issue.

Did you check to make sure that you have 12V+ to the coil. It you do, it would have to be either the coil or the CAS.

I know you can check other coils with multimeter, not sure about the one on our cars...

Good luck with the fix

Or power transistor.

Have the caps been inspected or replaced in the ecu?

I set my timing to my books standards and my engine turned over fine now I put it in the engine bay hook everything back up and I can't crank the engine over it just stops after a small crank? Any reason why it would be doing this

 

[Dsmkauai]

Are all your grounds in place and tight with no corrosion? All the wires to the starter tight? Is your battery any good? To me sounds like a weak battery or bad connection. Slow or clicking starters often end up being a loose or coroded connection? Double check your work bro!

 

[lbz34]

Sounds like you have an AEM, if it is reading 100% throttle then it will in a flood clear mode and you will not get any fuel, you need to go to wizzards and calibrate the tps so it reads 0 then worry about making it work.

 

[lebon29]

I haven't even tried turning it over with the key yet just by hand.

I shoulda been more specific

 

[NordicSaab]

It wouldn't turn either way? Even if you have some valve contact you should be able to rotate back part of a turn

Remember that if you have the head on now and didn't before you will have more resistance from compression.

Pull the plugs and see if you can turn it over.

 

[lebon29]

It turns Alittle bit but not much and I just took the plugs out and tried it same thing. why would it be hitting the valves now and not when I first hand cranked it before I put the engine in the car

 

[NordicSaab]

Idk... Why is not turning over now? Could have jumped timing, could have lost a wrist pin, dropped a valve... Anything

This is dumb, but when you try to turn it you're doing so with a large wrench or breaker bar right? A new engine can sometimes require a lot of force to turn...

If you can't get it to turn, it's time to pull the valve cover and if nothing is obvious there, pull the head... It's the only way to not risk breaking/bending anything

Also, is there any chance you left a rag or debris in the oil pan when you put it on? Don't laugh, I've seen it happen...

 

[lebon29]

I shall try the breaker bar

 

[SaulHudson]

I do have an aem.
The problem with the throttle has been resolved. It has not been calibrated but it was not getting pwr and grnd to tps before.

I swapped the coil pack and ignitor, to no avail.

So I have a 98 420a that I rebuilt from top to bottom, new sensors all around. i have been trying to get the minor issues sorted out so i can get it inspected and on the road. The other day i was driving and it just shut off in the road. kept trying to start it and eventually it started and i made it home. I traced the problem to be lack of spark. I let it run in my driveway and it shuts off just idling as soon as it reaches temperature. it finally dies and will not start back up. I have tested the coil, camshaft position sensor, crank sensor, ASD/MFI relays, etc. Everything checks out good. I did notice that the white speedo gear in the trans is not here it's supposed to be. it's there, but pushed towards the front of the car to the point it doesnt engage the VSS. My speedo doesn't read obviously, but i'm not sure if this could lead to a no start condition. My other idea is that the ECU is going bad. if anyone has any pointers or ideas, please share them. thanks

I have had the problem of it shutting off and it ended up being the battery post was not tight enough so it caused the car to shut off and not turn back on sometimes. Could be that I suppose, could it be your alternator?

 

[Brax93]

had a issue on mine when it reached running temp it would turn off and you would have to wait from like 20 mins to a hour then it start like no problem till reached temp again and would die..... had it happen 2 eclipses I own... it probably is is your crank position sensor... if its dying when you get ti running temp hope that helps..... that effects your timing with spark so yeah

You said it was good but that whats was wrong when it happened to me just to tell ya

So I have a 1992 eagle talon that the previous owner did a hack job on the electrical. We removed the engine harness and fixed a lot of the connections.

We just installed the engine harness and connected everything up and are getting a no start. The check engine light is not activating but the car will not start just turns over.


I did some reading and it shows that you can check codes by test light patterns but that does not sound fun... I have called the 3 local auto parts stores and none of them have the correct connector.

Any suggestion on how to trouble shoot? Any suggestions on what may be going on?

 

[SoonerTalon]

Bumping this as no one has replied in a couple of days.

Are you getting spark or fuel?

[SoonerTalon]

Yes to both.

A couple of things to note is that I have a 2G MAF and DSM link installed on the car. Both were installed before the engine harness was tinkered with and ran fine. Any chance that the EPROM would have been reset due to battery/cable disconnects?

Sorry for my delay in response I'm sick. It is a very high probability. How long have you had the car? It might have a battery in the ecu to retain its data for a curtain amount of time. It also may need a constant power supply. Do you have the software?
