Here is the story.
I've got a buddy's truck in the shop. It blew a headgasket in Florida and he had it shipped up here to me to work a little magic on it as well as fix it.
The head, twins, and the battery on the passenger side were removed before shipping (by a supposed reputable shop in Florida) and the cables hung loose
However the driver side battery was still hooked up. So, that could be in the equation, maybe not. The cables could have very well touched something they weren't supposed to. But all fuses check O.K.
These are the specs.
04.5 4wd Auto
Old Package
Piers Twins
Piers Injectors
Studs
TST Twins
Power Pup
Air Dog
Suncoast
New Package
Silver Bullet
II Injectors
II CP3
FASS 200
SMDiesel Nitrous
SMDiesel Rings
ARP Studs
Suncoast
The TST has been removed, the pup is still on the truck just because I don't want to risk corrupting the ECM until after we troubleshoot this problem.
There are no modules currently installed on the truck (TST,Edge etc...).
I have tried to remove any possible complications.
The symptom/problem is this.
When the key is turned to the RUN position or the ACC posistion you can hear multiple relays under the hood cycle on and off in sync with each other.
The batteries test O.K. and this is even with a good charger hooked up just in case of a low voltage situation.
Tommorrw I'll eliminate the batteries from the equation by replacing them with new ones.
Also, when the ground cables are connected (hot already connected) you get a small arc from the bat post to the cable.
I've seen many 3rd gens do this, but this one seems a little bigger than most (could just be my imagination).
They will do it as long as you leave the key on. ON,OFF,ON,OFF,etc...
The normal scanners don't pop up any codes (no suprise there).
I don't currently have access to a DRB3 tech tool, but I'm working on it.
I haven't tried cranking the truck very much because I would like to come up with an answer for this problem first. But, the motor does crank over (haven't started it yet).
While they're doing this the fuel pump relay follows suit, that means the FASS just sits there and goes on,off,on,off. Which is one more reason I haven't just tried to go ahead and start the truck and see what happens.
I've done over 30 3rd gen head gaskets. But, I didn't tear the truck down originally, I don't know if there is something I missed puttin it back together.
I did try unhooking the injector harnesses at the valve cover just in case I had an Injector with bad electronics or something. No help.
Let's here it guys.
Thanks,
