No engfne even stated.
why not say what "not working" means.?
Engine cranks ok but will not start, RIGHT?
Ill pretend fuel pressure is 0 PSI cranking right.
IMMObilzer light glowing? bingo.
interial switch tripped (was in a crash>?)see photo below...
The PCM sees dead spark so cuts all fueL? sure.
(it will, if it does?, scan it yet? cranking, that be first.)
The PCM can cut fuel for many reasons.
2 dead sensors, and spark dead on the tacho line.
1,2,3 bam
and immo set. 4
and the inertial switch, if fitting many are not.
what matters most (1st) is 12vdc to the pump actual cranking, does it have 11vdc at least>?
if you see 12vdc and PSI is 0 or not spec cranking
at the rail, then the filter can be clogged.
not just a dead pump,, i cant hear pumps cranking so.... i use TOOLS> to see whats going on.
to a DIY, vast answers.
1: makes noise.
2: fuel rail drips or not.
3: 12vdc missing to pump or not, cranking?
4: 0 (zero) PSI pressure at rail cranking
????????????????????????????
you need 3 tools to diagnose EFI.
a voltmeter
a fuel pressure gauge
and if savvy , the scan tool (as low as $10)
ill not mention hand tools as that is obvious.
got tools? (like the milk commercials)
or must we work totally blind.?
post engine in car and we post schematic of the ECU, and how she works.
can do.
if you log in to alldata.com you can too.
the law of the West. 1/2 of cars made , the pump does not run unless cranked, that is why I crank them all, and not waste my time trying to learn the PCM internal logic for that., some cars are even reflashed to only pump cranked, i can name them..
and point 2, it not starting, so crank it...
