Ok so i bought this heap...er truck this past weekend because of the motor. Its got a 360 magnum with low mileage and good compression on all cylinders. The problem is an electrical one now. It has no spark. The former owner had the ECU rebuilt, put a new crank position sensor and it appears a cam sensor in it. He says he only did the crank position but the cam sensor looks sorta new too. The relays on the drivers side inner fender are clicking when the motor is cranking but the coil is not sending out spark at all. From all my reading it seems the likely culprit is still the cam position sensor or a splice in the wiring somewhere that goes bad? Anyone else able to help out with this one? It had the former owner stumped and i would like to get this up and running and then into my truck lol.


forgot to add i pulled the codes and it is getting a code 11 which is timing chain/bad hall effect/cam sensor/crank sensor. Any or all of those. Oh and motor has somewhere south of 39k miles on it.

 

R u getting fuel?

Dave

 

Yes i forgot to mention that. Im getting fuel pressure at the rails.

 

Is it squirting fuel when you crank engine?

Dave

 

We held the shraider valve open with a screwdriver and cranked it and it did not squirt but after a few cranks you can push on it and it squirts fuel out under pressure.

 

Could be that its the ASD relay.

Dave

 

Isn't the ASD relay one of two that is mounted to the drivers side inner wheel house? I tried two different relays in there and it still would not start.

 

Do you have the factory service manual for this truck?
If so check to see if it has fusible links.

Dave

 

I have the Haynes now. I do in fact have fusible links on the inner fender. The haynes does not go over testing them however. Do i just stick the prob through the rubber lining on the wires and make contact that way? Or is there a better way to check for broken wires.
