I am by no means a mechanic and I have a problem that none of my friends or I can fix. I recently bought a 98 f150 4x4. It ran great for about 3 weeks and then just quit on my wife one day about a month ago and hasn't ran since. I have a 2nd 1998 f150 that runs great so I have traded out several items and bought new, several items. There is no fire at the spark plugs. We tried changing coil packs, crankshaft position sensor (new), cam shaft position sensor (new), we've traded out the whole air intake system, we rented a scanner from autozone and all it said was what we knew, no fire to the plugs. I checked all the fuses and swapped around all the relays in the distribution boxes on the driver side under hood. I checked to make sure the fuel cut off switch in the passenger foot panel was pushed (although I know this has nothing to do with fire to the plugs). I am at my wits end and can't afford to take it to a shop. Any ideas would be appreciated.
