Re: 1993 Ford F-150 Starter Problems?
The problems you guys are experiancing is more likely than not related to the starter activation wire on the starter solenoid. Check this wire very carefully by pulling it off, and examining the connector for corrosion, and or cracking. The easiest test to check for starting problems is to first check that you have 12V at the starter at all times on the large 4 gauge wire at the starter, if not check wire all the way back to the battery for problems. (remember never to rule out the simple like a poor connection at the battery, sounds simple, but have seen this missed hundreds of times, so just take it off the battery and clean it! it will take you 30 seconds, and can save tons of headachs!) Next have a person in the truck and turn the key to the start position and check the small activation wire on the starter to see if it is getting 12V, if not go and test the starter relay from there. Hope this helps, if not let me know.
