cam sensor or crank sensor

[woomer]

ive read what i could find on here.i have no spark and no fuel ....replaced the ecu checked fuses tried to cover all the basics -its a 95 talon nt ......will either of these sensors gone bad cause fuel and spark both to stop?.........i need help quick

ckp causes no spark. as for fuel are you you sure your not getting any fuel if not get a buddy and a mechanics stethoscope have him turn the key on and you listen for the fuel pump to cycle with the stethoscope on the tank

im sure there no fuel no relay noise and fuel in rail .so ## saying its not the crank sensor?

It's late and I've been drinking but I recall that all 1g and 2g cars (turbo or non-turbo) will not activate the fuel pump until the car is actually cranking and getting pulses from the crank sensor...in other words, turning the key to the "on" position does not turn the pump on. I'm not positive about the 2g N/T, though, so you should probably search to make sure. That's about all I'm willing to say about a 2g N/T at the moment.

It's actually coil pulses (which also need those sensors pulses to be generated) that need to be there for the ECU to turn on fuel pump on dsms - except...you guessed it, not on the 2gnt since it's a Chysler engine (it primes with just key on).
Yes you need CAS and CPS sensors working to get spark and fuel injector firing.

ok then your saying except for my engine if theres no fuel pressure or priming -it cant be my sensors?.........yes im sure theres no fuel pump running --any suggestions .thanks for your input

Not if you're running everything electrical stock. Check for voltage into and out of FP relay. If there check back at FP. If there suspect FP.

ok i dont have spark either i suspected the ecu but that didnt work either - so i asked about the sensors ,,,,,

ASD relay working which powers most engine stuff?

ok i found out i had gotten 2 faulty ecu's so im fixed for awhile --- can any one out there tell me what year ECU'S will interchange with a 1995 Eagle Talon n/t ?
