Hello, I just bought a 99 f250, superduty, 5.4 gas, 5spd, 4x4, reg cab. I bought it with the clutch out for a good deal and havent had time to get it in.

My problem is when the truck was deliverd the guy said the wipers didnt work...well they do now..makes no sense? Next...sat morn I'm headed out to put the clutch in it..truck running I cut the headlights on and the truck dies. When I say dies I mean like someone pulled the batt. out of it, absolutly nothing.

I thought it may be the alt. so I charged the batt. put it back in and started the truck. Pulled the hot wire to the batt. once started..all good, alt. is fine. So I cut the headlights on again...DIES, and nothing again.

I proceeded to check for obvious malfuctions (fuse's blow/burnt ect.)and nothing. I let the truck sit for 3hrs+ till my pop's got here (ASE cert. mech) and he starts the thing rite up like nothing is wrong?????????????? We looked for stuff and checked, and looked and checked, trying to make it do it again...he says "I cant fix what isnt broke" could not get it to do it again.

I have tried for 1 1/2 days every cuople hours to get it to do it again with no "luck" I'm worried it will happen while driving down the freeway or something and hope someone could shed some light on it...thanks in advance

Sounds like a bad connection somewhere. I'd start with pulling the PCM's harness and spraying it with contact cleaner. On the 99-01, the GEM is mounted under the dash, it's worth checking the contacts to it as well.

 

Very good idea, keep them coming

 

I went crazy trying to figure out weird lighting/electrical/operating problems in my truck (including having the engine electrically die when I put it in Reverse [sometimes]). It was the main fuse panel under the left side dashboard ..... wetness was causing it to shortcircuit in odd ways. On close examination, I found burn marks in it.

Good luck.

also check for solid ground. wierd things happen when vehicle or equip. have weak ground
