I have a 1994 Ford Ranger 2.3 manual that will not start & usually only does it when it's hot outside or I have been driving awhile, then I have to let it cool down before it will start again. Then I switch the fuel pump relay with the ac relay then it starts right up. Sometimes mine can just sit in the heat & not be started all day & won't start. If it doesn't start the first time I just switch the fuel pump relay with the ac relay & then it starts up but idles weird, then after about 15 min it clears up. In my opinion they should have had a recall. I love my truck even though I bought it 3 months ago, but I had a 95 & hated to give it up. This problem is the only reson the seller got rid of it. He put brand new coil packs, starter, all plugs & wires & he didn't know what it was. But he said after it cooled down it would start just fine. After I got it & it did it the first time on me, all I did was change the relays around & it started right up. I am not certain on what it is but I have been on several forums & alot of people are having the exact same problems.

i live in jacksonville fl. and my truck(93 f150)was doin the same thing. i changed all my grounds to the motor firewall etc. and the problem has stoped. my truck would sound like its battery was dead, and i realized the started would be really hot so i would pour about a gallon of water and it would start rite up. changing the ground wires seem to do the trick for me.i hope this helps , good luck!

I had the same problem with My 1990 F150 300 6cylinder 4x4.....I cahnged all the same things you did, finally I sprayed a can of Gumout through the throttle body and it worked and ran great. Now I add fuel injector cleaner to the gas and a regular clean with the gumout and the problem has'nt come back. Good Luck to you and hope it works!

did you check the glow plug relay right on top of the engine?

Like Laurie Mack said. It is the inertia switch below the glove box. Here is some funny information. DON'T change the fuel pump first. Interesting fact: I bought the new inertia switch from Ford and the install instructions that came with it said to install the switch in the protected area to the right where the fuses are. It is like Ford knows it was a dumb place to put the inertia switch, but they won't let you know until after you buy a new one. I have read at least 20 other people on here that had the same problem I just had.
