2000 expy no start

[mstng86]

2000 5.4 won't start. Turns over but doesn't start. No spark to plugs. What's the possible problem?

Crankshaft position sensor is where I would start. Any codes?

[shumpertdavid]

If the check engine light illuminates during cranking then the pcmcia isn't receiving a crank position signal.

[mstng86]

Ok. Will check that. Haven't pulled codes yet..


Check engine is off when cracking.

I believe PATS will only kill injector pulse.

Correct. It kills fuel, not spark. I'm still looking at the crankshaft position sensor, aside from fuses or the PCM, it's the only thing that can cause a no spark condition.

I have a known working CKPS if the OP wants to test it out.
