Car will not start?

On stands for 4 months now. Sheesh.

Got trans in today, and all smooth. Wanted to fire up motor but no exhaust yet.

Turns over great. Will not even try to start. Ideas?

Does the tach move?

If so, then check for pressure on the fuel rail in the engine bay.

Check to make sure your CPS (Crank Position sensor) is plugged in properly and make sure its not defective...

I wiped it off really well inside. Didn't check to see if plugged in.

See if the thing is firing, if not, well there are quite a few posts indicating how easy it is to bend a couple of the flywheel tabs making it hard for the crank position sensor to read the position of the crankshaft.

The Flywheel is brand new, and great care was taken to set it gently down.

Not even a sputter. Just turns over smooth.

Start with the basics then, look for fuel pressure, spark, and compression

Tach moves. I can smell gas. No ignition. Wanted to get it started before 100% reassemble.

Guess I'll start with fuel pressure. What's the best way to check for spark?

Ran perfect before IMS and trans R & R. Checked timing. Was perfect after two spins.

Pulled CPS. Still magnetic but looking for a new one now.

Just used an inspection camera and checked all the way around. Perfect.

Just need to find a CPS local. Don't know how to bench test it.

If you have a Ohm meter, pull the connector and put probes into pin 1 and 2 you should read around 800-1000 ohms, then repeat the same test for pin1 and 3 and it should show infinite (meaning open/as if not touching). If either of these is not the case I would replace the CPS.
Hope that helps

Let me guess: an aftermarket lightweight flywheel......

No. OEM from Pelican as part of a master kit. DMF

CPS ohms exactly as described above. Will reinstall.

Used a color inspection camera and looked at all the teeth on the flywheel. They are right there and perfect.

Thanks.

New clue. Windows do not drop when door is opened.

No moisture in immobilizer / alarm possible.

Fuel pressure and spark. Standard Schrader valve pressure tester.

Hmmm. Some of the immobilisers have a fuse on the unit itself

What is the procedure for testing for spark?

I'm here late tonight to fix this.

I can smell gas from exhaust, but have not checked pressure yet. Ran 100% perfect before this.

I do it cave man style, pull out a coil, stick a spark plug on it, ground the outside of the plug, and have someone crank while I look for spark at the plug.

But if it WAS the immobilizer would the engine crank over?

Dunno, can't remember that far back.. I guess I'm the beginning stages of Alzheimers. Been more than two years when I had a issue with an immobilizer
