I had replaced the lift pump about 8 months ago. I could not get it to prime. Jeff got me to bypass my fuel heater and i finally got it to start. I drove the truck for about 2 months after that with no problems. I was going to a place in Georiga to ride dirt bikes and it shut off, the other side of atlanta. I could not get it to crank. As for the reply about Preston, in my opinion he is the man too. I called him in Georgia and he talked me through wiring up my fuel shut off. I got it started and was on my way. I only had third gear, no rpm or speedo,no cruise,no air, and no power. I got it home and tried several web site to try and find out what was wrong. Nobody new. I had alot of good suggestions though...Jeff told me to check the main fues pannel on the inside of the truck. The one he told me to check was blown. I replaced it and it blew again and again. What had happend was when I bypassed the fuel heater I did not dissconnect the relay.. It kept trying to turn on. When it finally went out it shorted the 10 amp fuse in the main pannel.. All that had to be done was dissconnect the relay. Sounds so simple but it was so frustrating. Jeff also turned up my idle for me while I was there.
