- 1999 Limited 5.0
Kind of a long story. I have a 1999 5.0 Limited. Has been a great car other than the gas milage. Towed a 23' camp trailer as well as my full size truck(power wise). Anyway, wife got a gas miser car for her commute to work. Explored was parked. Had a family friend who lost her transportation, so we insured the Explorer and let her use it. Things were fine for months, then one night she called and said "parked it in the driveway, went back out to run an errand, no start." It ran perfect up until that last park job.
Me being me figured it was out of gas, so I took 5 gallons of gas over and gave it a try. No start. So I loaded it on the trailer and brought it home.
She found another car with the help of her parents and is back on the road in days. But that is another long story.
Back to the no start. I let the Explorer sit for 2 years. Fast forward to last week. Wife is tired of it sitting in the driveway. Get the kids to help me push it in the shop. Charge the battery and try it again. Nothing. So on a wild hair I decide that the fuel pump is shot. Didn't check pressure, just knew it was bad. Hit the forums up here and dove into dropping the tank. All went well, drained all the old fuel and added new. No start. Bench tested old pump and it works fine. Yeah i'm a moron. In the mean time, the starter goes out.
Took a few days off and bought a starter. Now i'm on the forums learning all I can. Do a compression test and have low 40's on 123&4. Did not check 5678. Oil does not change the reading, off to the parts store for a timing set. Tear down went well other than the clips on the AC and radiator. That's easy once you have done it once. Well, dots on the old timing set is perfect. Go ahead and swap out old for new. Buy a new compression tester and have 120+ ON 123&4. not excellent, but should be enough to get it to run. Now I'm really reading the forums.
I have fuel pressure.
I have fuel on new plugs. Injectors must be trying.
I have spark at all 8 plugs through the wires.
The syncro is turning when I crank.
Pats blinks every 2 secs. Glows for about 3 secs and goes out when I crank. Tried both keys.
Original crank position sensor. It sparks so I have ruled it good.
NO CODES.
Cleaned and added grounds at PCM.
Removed PCM, opened up and did not see any burns. Not that I can see a bad PCM with my eyes anyway.
Starting fluid does not change a thing.
Tried a different battery and jumped it with 4/0 cables off my diesel truck.
I'm at my wits end. Thinking my next move is to tow it to Ford.
If the PCM is bad or needs reflashed can I use junkyard parts? I plan on pulling the PCM, PATS module, keys, gem module thing from drivers rear, and maybe the key sensor. Reading various locations for the PATS module though. Where is it?
Any advice would be greatly appreciated. Thanks
