I have an '01 Ranger Edge 3.0L that has trouble starting. It will start in one of two ways... 1) It will turn over for 10 to 20 seconds (at normal starting RPMs) and then barely kick over. 2) I can turn it for a few seconds...Stop...Try again and then it kicks right over like a brand new truck. It has 85,000 miles on it and has been doing this on and off from 35,000 miles and is getting to be more on than off. I have changed the plugs, wires, fuel filter, run SeaFoam through the gas and intake, and put in a deep cycle battery. I'm stumped. I even ran a diagnotsic on it and it said nothing was wrong... The truck runs great, but this is getting annoying.
