TRUCKS DEAD

[Zookie400]

we dont have injection pumps. we have heui pumps(high pressure oil pump, and low pressure fuel pumps.

did you check the oil?
did you check the fuses with a test light, or did you just look at them?
did you chek ALL of the fuses?
does it have any faults/check engine light on?
was any work recently done to the truck?

Heres the story. Ive had the truck for about 3 months now. The truck ran like a top. Then I got a TS performance chip. Installed the chip and on came the problem. When I went to change different positions, it stalled out, but would always start right back up. The chip did work also, aside from stalling out while switching. Went to the store, and was fiddling with the switch to see if it would still stall. Of course it did, but hasent started again after that. So I towed it home and drove my old truck, just now gettin around to fixing it. HPOP reservoir is full, all fuses are good, no check engine light, dont have a scanner but ran the key codes, came back with E 08 6, and 1031CAL

Are you sure you cleaned off all the silicone when you first installed it? Remove the chip and make sure the contacts are clean.

ya, the chip is removed now, and all the contacts are clean. I used a 3m scotchbrite pad.

Mine did the exact same thing , showing the settings to a friend...the first few times it stalled ,it restarted. One time not...
The IPR was stuck...
New IPR , started right back up..In the mean time I had tried CPS, IDM PCM,Checked the HPOP oil,Relays ,Chip R&I ECT...

BTW...DON'T REMOVE THE CHIP WITH THE KEY ON ......

Did I say that loud enough......

 

[Dieselmech]

Found out the problem. Fried the PCM. Dont know how that could have happened. Both batteries were disconnected when I installed it, and it ran after. So now I dont know what to do about this chip. Dont want to put it back in, scared it will burn another pcm up.

If you put the chip in ,witout starting (using the batteries unhooked method), I did this also, If the chip is bad , you will get a CEL with the key on.....
