s52 obd1 probs

[evoDRichie]

ok so it cranks of coarse but no fuel comes out and no spark...

power is going to the injectors and fuel pump yet neither are working

no CEL, ive checked all the grounds multi times, chip is not in backwards and spare unchipped 413 is not turning it over either...

any advice?

Chip is not in backwards.

Ruled out what I was going to say... As I did that with my car.

If you don't have spark then it may be a relay... If you had everything but fuel, I'd say the lines were backwards.

[evoDRichie]

lines are off when cranking no fuel comes out ... after testing my whole wiring harness with a multimeter i have come to the conclusion that my crank sensor or cam sensor may be bad... the crank sensor has .39 and i cant get a reading on my cam sensor... how much resistance should they have if any, anyone know? .. also would this cause no fuel /spark, if one of those sensors were bad?

[FredK]

Yes. If the crank sensor is bad, there won't be any fuel or spark. The crank position sensor should ohm out at around 540 ohms.

[evoDRichie]

well then i believe it is bad

[evoDRichie]

Will the bad crank sensor cause no CEL?

[328ijunkie]

^sometimes yes. And all the motor needs to ATTEMPT to start (I.E. Fire spark/fuel) is crank signal. you could have EVERY other sensor unplugged and it would still start.

Have jumped the fuel pump just to make sure there are no issues there?

Have jumped the fuel pump just to make sure there are no issues there?

have not planned on doing that today...

[jrdeamicis]

if you dont have a Cel you either

Wired C101 wrong

or

The ECU is dead

or

The CEL lamp is out.

GO!

she lives! CPS was bad... and i guess my bulb for my CEL is just burnt out
