Truck was running the other day while I was loading it when it died. It was very cold out and my tank was nearly empty so I thought it may have froze. Out it in garage and heated it up for several hours. It started but just for a couple of seconds then died, did this repeatedly til battery died. Thought maybe there was just to much water in the fuel so I added gas til tank was half full. Wouldn't start. Checked relay(removed and tested for click)checked voltage from relay PRIME terminal to ground voltage present when pump cycles on. No "whirring sound from pump and no pressure at manifold. Replaced fuel pump and filter still no start. Checked wiring harness, jumped relay prime to positive battery cable and tested voltage on grey wire on plug to fuel pump at pump-no voltage, good continuity on black wire to chassis ground. What am I missing? No power? I don't know what else to test. As a side note this truck had started very rough in cold weather for 4 or 5 years now with constant engine codes of lean right and left bank and engine misfire but learns it way out of it after about 10 minutes.
have the same problem?
