I just installed a GDS FPR spring. It's suppose to be like the shim or bb mods. I put it in perfectly fired the truck up it seemed to run fine. I took off down my road then my truck acted like it ran out of fuel (it has 1/2 tank). Now it won't crank or run at all. I've tried taking it out and putting the stock spring in several times and nothing it won't hit a lick. Please help! Thanks in advance!
I would make sure you still have power to your fuel pump, and if so then replace the pump. You could have had a weak pump and the added pressure of the new spring caused it to fail.
