94 ford f150 flareside 4x4 5.8L
ok my truck broke down a month ago and replaced so much on it to find out the computer fried
getting a new computer tomorrow after my check goes through
but before i put it in i want to make sure nothing fried it
alternator is in perfect condition tested three times
battery is great and new
completely new starting system (year ago)
timing chain and re timed the ignition
new spark plugs and wires
new ignition module
wires are all ok and look great from what i can tell
truck is rust free and in great condition
what else do i need to look at before i plug up the new computer

 

Just make sure the contacts are clean, smear them in some dielectric grease, and make sure the battery is unhooked. My personal preference is to keep the battery completely unhooked, but I don't know if you can have just one battery cable or the other unhooked and be okay.

 

how did you decide your computer was bad?

lol thats how and on the other side the chip is melted and burnt

 

Yeah I'd say she's fried alright...

Double check ALL wiring leading to the computer and make sure none of the insulation has rubbed thru. You should probably also check your grounds as well.

 

iv done all that when we was first trying to find out what happen

 

wow what the hell!!!! i had my 92 f-150 302 and my 94 lightning burn in the same freaking spot!!!!!

 

Does anyone know of a service that rebuilds these?

my 93 F150 burned the same exact way on Tuesday. I went looking for a new computer at the junk yard but someone already pulled them all. And a new one is several days away.

 

well my computer new is $247
so i went calling junk yards and no one had one but the gave me a number of ppl in nashville tn that can fix it no matter what so i asked how much and they said $300 lol so they are smoking crack i rather have a new one for less the price

 

after some horse trading, ny 92 150 cost me around 500. It ran for a thousand miles okand now the fuel pumps keep running so everyone agrees it's 'puter time. They say there's no real way to check the computers so I wonder a) how they build them in the first place and b) how do they test them after a Nashville rebuild? I asked the jyard guys if there were like 10 different ones for 1992 and he said more like 40 so I have to pull mine out and get the actual numbers off it and hope that's the problem. Tell me again why we like these trucks?

 

Another reason that I'm switching to a carb'ed setup! I don't need the extra aggravation!

 

me too but I hear the computer controls the trans shifting and some other stuff. I wonder what years are compatable

 

check all of your grounds. they computer itself has to be grounded as well. this is most of the time acomplished through the mounting or sometimes there is a separate ground wire.Faulty wiring is usually to blame for computer problems.
