pcm

i ran some trouble codes on my 1992 explorer and i got a code 513,114 and 116, i looked up a 513 and it says pcm internal voltage failure does that mean i need a new one? and also my explorers fuel injectors seems to be putting out a rich mixture of fuel. i pulled all spark plugs and checked...

Having trouble getting my 95 explorer 4.0 start. The starter is firing and the plugs are also firing. I have no pressure at the shrader valve. I changed the fuel filter and while the filter was off i turned the ignition to on position and can hear the pump working yet no fuel comes out of...

an ex with 21k that just needed PCM/TCM reprogrammed? Posted previously about my 02 Ex that Ford couldn't figure out, so now I just decided to buy a different one, a newer one. Found a 2007 Limited with V8, 21,000 miles, but upon reviewing the service recs, found it has just had the PCM and...

This is a new one for me. My wife took our daughter to school the other morning, came home for an hour, went to start the truck again and it was dead. No chimes, no radio...nothing. I came home that night, tested the battery charge and it was as dead as it gets. Time for a new battery anyway, so...

Hi all, first time posting here, but I'm going absolutely mad. Have a 1992 Aerostar XLT (4.0L, E4WD) that has been passed down through a couple generation in my family. My grandmother got it new, gave it to my mom about 5 years ago. She wrecked it, got it fixed up new, then the alternator died...

My 1994 Explorer will not start. I checked the inertia switch it is closed and good. Checked fuel pump relay coil is good, relay changes state with 12 dc applied to the coil, and the normally open path closes with 12vdc applied to the coil. So like a fool I replaced the fuel pump. Truck still...

The EEC-V on my 97 mountaineer 5.0 is fried. I don't want to spend over $150 at a parts store. the four letter code on mine is SLL3 the part number is F67F-12A650-TD my question is, can I simply pull a computer from ANY 5.0 Mountaineer, or do one or both of these codes have to match.

I have been experiencing a check engine light and poor gas mileage for the past 5 months. I have had a P0442 evap leak code but the ex passed emissions and on a scanner it shows that the evap system is ok. Every time I have reset the PCM the system monitors report inconclusive but all of them...

Hi everybody- This site has helped me greatly, so I thought I'd join. I own a 94 4.0 4x4 explorer. It needed an engine swap, so I just put a 91 engine in it (My dad wrecked his 91 with a good engine, so it was the only one available). The 94 had EGR but the 91 didn't, and now I'm pulling an...
