-----saw a tread about egnition key and module could that be the problem-?-----------started out would die on let it sit a little would start back up,, a week later died would not start put on a used crank sensor forma 60k used engine we have here started right up drove for about a week died bought new bossch sensor would not start -it turns over but its like its not getting fire ---could it be the key and ring and module ?????? thx to all for help
Outside possibilities :
1. Camshaft position sensor.
2. SKREEM module ( as in thread about ignition key and module )
3. Fuel pressure ( there is a port on the fuel rail front passenger side of the engine, when it won't crank, just remove the cap and press the valve with a match or something and see if you get a face full of fuel )
Basically, if an engine turns over with the starter and won't fire, then it's usually one of these problems :
1. spark
2. fuel
3. timing
4. compression
