1993 F150 computer repair

I took apart the computer and found water had corroded a capacitor so I replaced it. This video shows the computer location and supplies. I got the capacitor at radio shack for $1.48. Saved about $950. Your problems may be different but look up testing circuit boards and soldering circuit boards before attempting repairs. One slip and you can destroy your board, but what the heck, you wouldn’t be working on it if it wasn’t broke anyway.

Remember to disconnect the battery first and keep stuff clean. Seriously, take the time to learn some about working on circuit boards. These boards are fairly simple and you should be able to find the parts, it’s just that things are small and you can easily make things worse.

Attempt at your own risk and follow the repair manual when removing and installing the computer.

    I replaced my capacitors and they lasted about four or five years and I ran the truck once every month or so. Those capacitors leaked out and the board fried but there may have been other issues due to corrosion. I got a remanufactured computer and put it in and it only lasted about six months and the truck started running, shifting, Not engaging in cruise control, and the ABS light coming on, and idling erratically so after following the manufactures test procedure on the anti-lock brake module it told me it had a bad ECU. I pull ed the computer out and looked inside and sure enough a capacitor was starting to leak again.

    The computer is still under warranty until next February so I’ll go ahead and change it out but if this happens next time I’m going to put different capacitors in of the SAME microfarad rating but a higher voltage.

    See the following video for why I intend to do this. https://youtu.be/Noy4YAjoJE4

    My 94 5.0 has no power to the inertia switch or the fuel tank selector switch. The fuel pump fuse and relay all test good. Any suggestions?

    could you run a video on how you took out your computer? And how you repaired the circuit? This would be very helpful. thanks,
