Well I was drivin down a main road, truck died while driving, I coasted off to a parkin lot and got towed home. Heres the symptoms, but I think I'm hot onto the problem.

My battery light is not flashing, but pulsing as well as volt meter.
No WTS light.
If I turn the key 3/4 way to start, and go under the hood, I can hear something shortin out. Wires to the glow plugs???

 

Could be your gpr staying on and draining your batteries

whats your volt meter reading on the dash?

 

volt meter is at the N of normal. I can here clickin noises when i turn the key to start.

 

Sorry Seen it is pulsing maybe alternator?

 

Don't think its the alternator. If i take this one little red w/green stripe wire off, the shorting out sound goes away. I'm just tryin to back track this wire, find the s hort.

 

Which wire are you talking about one on the gpr?

 

Yea, the gpr looks like the starter solenoid correct??? If i take that little red wire off, the clickin/shortin noise goes away. I'm goin back out now to hunt down the problem some more.. If i had a pic i'd show you, dont even have a camera around now.

 

red/lt green goes from fuse #22 (hot in run or start) to the latching coil of the GPR. the circuit is completed through the purple/ orange wire to the #101 pin of the powertrain control module, where the module gives it a ground to complete the circuit. you could have a short in the ppl/org wire, or a false signal from the pcm.

 

X2 or the relay itself is shot

 

I was just out playin around wtih it, didnt get too far. If i turn the key to start, and go under the hood, I hear loud clickin noises, comin from the gpr and the relay thats in the power distribution box (second one over from drivers fender). Its just a PITA tryin to trace the wires back, find the short.

 

Forgot to mention, if i take my ohm meter and go from either wire to ground, its open like it should be,

 

Is it blowing fuse#22?

 

Are you testing the two small terminals or the big ones?

 

No fuses blown.

 

I tested all of them just to see. THe small terminals are readin open. However if i take the small relay out int he black distribution box, it still makes the ticking/shortin sound. does the little relay feed the gpr relay or is it the other way around????
