HELP!! Truck Won't Crank Over!

[mberry]

I just installed the TST PMCR and now the truck won't crank over. What should I look for? I checked and rechecked all the connections and followed the instructions to the letter. Please help ASAP! Thanks.

OK. So I just took the TST off and it still won't crank over at all! WTF??? Someone has to have an idea of what to look at? TIA!

Start with the simple things: are both batteries connected? Did you push in the clutch and put the transmission in neutral?



What does the truck do when you turn the key to start?

Check the fuses & relays too. My 2 cents. Dan

Turns out, for some reason, the starter solenoid relay isn't getting ground. I swapped all 3 realys and it does the same thing no matter what. It's going to the dealer ASAP. Thanks everyone.

Maybe check the big ground at the bottom of the block, I removed this cable when I installed my PMCR to get a better view of the crank and cam sensors

I checked everything at least 3 times. Thanks for all the help!
