Like the subject says, I’ve been fighting this almost a month now.
2.2L Engine.
The engine turns over, but want start.
We have fuel pressure (55psi) and a spark. Sprayed ether in the intake – nothing.
Changed the crankshaft positioning sensor. Put a simple scanner on it, it stated no errors or faults could be found.
Tried another ignition module, checked the PCM fuse and ignition module fuse, both look fine. Installed an anti-theft system bypass and followed the reset instructions. Didn’t fix. Just for fun we changed the spark plugs as well.
Now, the person I was with who saw the spark (I was inside the car) says the spark looked “weak” to him. Is this possible?
What can I look at now? I’ve already thrown almost $400 at this car with no results and I honestly have no idea where to turn next.
Any help would be greatly appreciated.
This says no spark. If true, you should see gas wetted spark plugs after no-start cranking. At least this would narrow it to an ignition problem…coil(s), etc.
Yes I do have 2 coils.
I don’t have a wiring diagram ( I do have a Haynes Book which is marginally above useless in my opinion)
I haven’t checked compression, but all 4 going out at once? I’m telling you the car was running great before this happened.
My daughter was backing out of someone’s driveway. After she started it, it just died. She says the Anti-Theft light was on when it happened, but I installed the anti-theft bypass with no success.
Looks like the Type 122 is the OHV engine discontinued(?) in the Cavalier in 2002 and the 2.2 Ecotec is the DOHC engine that replaced it. Simple for the OP to determine. The Type 122 had a more rugged chain, so I’d be surprised if it failed. It would also be interesting to know the miles on the engine…OP?
It seems to me that if OP removed the valve cover and spotted a broken chain, that rules out the OHV engine, which means they have the 2.2 Ecotec DOHC
On an OHV engine, removing the valve cover wouldn’t let you see the timing chain, I would think. In an OHV engine, the chain is further down. You’d have to remove the harmonic balancer and the timing cover to actually see the chain.
That’s how I see it
I just did some “research” and it seems OP has the L61 engine. There was a class action lawsuit involving Saturn vehicles of the same time frame, which had timing chain failures. These Saturns used the L61 engine.
