Hey everybody!
I have a 98 durango 5.2L, and it shut off on me when driving, and wouldnt start back up. fuel pump kicks on and pressure is good. it has spark off to top of the coil pack (tested at the end of the wire where it plugs onto the cap) BUT, QUESTION # 1, how good is good enough spark??? i test it with screw driver in the wire and laid it about a 1/4" from the engine, and it has pretty solid consistent, rapid pulsing spark.

but when i test the spark at the end of the plug wires, i get none. i tested voltage at the connector to the coil pack, and while cranking it jumps between 9 and 10 volts. QUESTION # 2, does this mean my crank and cam sensors are good?

tip of the rotor, and the terminals inside the cap are a little messy, but i dont know if they are necessarily bad enough for it all of a sudden to shut off and then never start again.

my first thought, is to through a set of cap, rotor, wires and plugs in it and see what happens. which i may end up doing, and thats fine. but im actually trying to sell this right now, so if i dont HAVE to do something to get it run fine, than id rather not right now.

any thoughts would be much appreciated!!
thank you!!

I moved this thread to the correct section.

If you have spark at the coil, but not the plugs I'd look at the distributor.

 

The cam sensor is part of the dist. I would try a crank sensor. Are you getting a no Bus message at the cluster?

 

not sure what a no Bus message is.
yea i am assuming something after the coil pack is the problem. i have about 10v while cranking, at the connector to the coil pack. is that correct or should it be 12v? does that help anyone with possibility of crank or cam sensor?

 

ok i figured out what a Bus message was, and i do not have one on the cluster! lol

well i put a cap and rotor on it, still no spark out the plug wires. the distributor does turn when i crank. could there be something else mechanically wrong in the distributor itself that is preventing spark? i know the cam sensor is in there, if that is bad will it cause no spark out the plugs? (even though i have at least 10v to the coil pack when cranking?)

if anybody has any thoughts, let me know, they are all appreciated! thanks!
Andrew

 

Look at the cluster. Cycle the ignition key three times off and on. Leave the key in the on position on the third time. Post the P code if it shows one. Like P0340 or P0344. If it doesn't show a code, then you need to get a scanner to read the codes in the PCM. And then post the codes.

 

ok here it goes lol

P0743 torque converter solenoid circuit
P0118 engine coolant temperature sensor
P0753 shift solenoid A
P0132 02 sensor circuit high voltage bank 1 sensor 1
P1282 fuel pump relay control circuit
P0138 02 sensor circuit high voltage bank 1 sensor 2
P0748 transmission fluid pressure control solenoid
P1765 transmission 12volt supply relay control circuit

most of these i cant see causing a no start. the fuel pump relay one of probably from when i took the fuel pump relay out while i was cranking it so many times testing for spark. with the relay in, i hear the pump and can smell the fuel a little after lots of cranking. as for the others, im sure all of these were probably present before it shut off on me, since the engine light has been on.

ughhhh this stinks!! was hoping for an obvious code lol. unless someone knows something from one of these??

thank you all for your help!
Andrew

 

The P1282 could be a problem, That maybe your ASD relay. I'm going to check my PDF files and let you know. The other codes are for o2 sensors and transmission.

 

The PDF file that I will be posting is what we use at the dealership.

1 Note: The following list of items should be checked before continuing with
any no start tests.
The battery must be fully charged and in good condition. A defective battery may
produce invalid test results. If the battery is low, charge the battery and then attempt
to start the vehicle by cranking the engine for 15 seconds, 3 consecutive times.
This will allow any DTC’s to set that may have been erased due to a dead battery.
Make sure the PCM communicates with the DRBIIIt and that there are no DTC’s
stored in the PCM memory. If the PCM reports a 9No Response9 condition, refer to the
Communication category for proper tests.
Read PCM DTC’s with the DRB. If any DTC’s are present, they must be repaired
before continuing with any other No Start diagnostic tests. Refer to the Symptom list
for the related P-code that is reported by the PCM.
Make sure that the CCD bus is functional on the vehicle. Attempt to communicate
with the ACM or CAB. If the DRB reports a CCD bus problem, refer to the
