92 Lumina Z34 won't start has spark

Hello,

I was wondering if anyone could point me in the right direction. This is a friends car she drove it over the other day and now it's won't start.

It cranks just fine. I checked for spark and I do get a spark. I can hear the fuel pump run when I switch the ignition to run.

I have read that it's possible that the crank position sensor may cause this. However I can't seem to locate it.

Any ideas???

If the crank sensor wasn't working, you'd have no spark. Offhand I'd guess she popped a timing belt. How many miles on it?

Pull a plug out and see if the compression seems weak.

It has 125,000 miles on it.

I still think it might be fuel related... She just bought this car and was showing me everything. It stalled while I was sitting in the driver seat and would not restart.

I have noticed that if it sits for a period of time and you try to crank it it sounds like it wants to start. I'm thinking that the injectors are leaking down after sitting.

I didn't change the fuel filter, maybe it's clogged?

It'd be worth trying. See if Autozone can loan you a fuel pressure gauge, test the pressure at the rail. Try seeing if it fires on some ether, that'd prove/disprove your suspicion.

The car has the anti-theft chip under the dash at your right knee. While turning the key giggle the chip and I'll bet she will start.
