dash lights and gauges erratic, truck won't start?
I have a 2003 F150 with a 4.2. When I turn the key on the first position, the dash lights blink and gauges sweep quickly. The truck turns over but won't start. At above 40 degrees, I can leave the key on, and in a few minutes, everything normalizes, and the truck will start. Colder, and it never normalizes. Today marks 6 weeks at the dealership. They have replaced the computer, transceiver and keys, none of which helped. They are at a loss. Does anybody have any suggestions?
