Runs fine but then won't start after that.......

[RareYellowAsp]

Okay here's the rundown,....I have a '98 with the battery relocated to the trunk. Recently, it's started this thing where it will start and run fine, but then when I turn it off, it won't even turn over again. I can jump it, and it will start, but other than that, I have to wait a while for it to start again. So far this what all I've changed out.

1. new alternator, FoMoCo
2. new starter, FoMoCo
3. new ground cable, hooked directly to block
4. cleaned terminals on positive cable.
5. new battery

I'm at the end of my rope here. It's the summer, my snakes a convertible, and I want to drive it.

Did you check all the fuses? Seeing how it starts normally and on a jump it's probably not it. But it doesn't hurt to check.

Again, since it starts, it's probably not your ignition switch. Just throwing thoughts out there. Any one else?

When you installed your new starter did you make sure the cables were secured all the way? I would double check those as well.

It was doing this before the new starter,....that's what made me drop in a new one.

Make sure you run a wire from the (-) bank of the battery to the chassis. The chassis needs to be grounded directly from the battery. Hope this helps.

Was grounded to body before, did it then also. Could it be an issue with the starter getting hot? Guess I'll try a heat shield next.

what gauge wire are you using from the battery to the front?

 

[RareYellowAsp]

Running "0" gauge from truck to front.

I know you said you bought a NEW starter but it could still be bad. It could just be the solenoid. Maybe when it heats up the contacts are not engaging. Maybe when you jump it with the extra voltage it free's it up and starts. If you alt. is checking out voltage output wise and your battery is checking out that only leaves electrical. If the wires were bad your car would not start all the time not just when HOT. I have bought bad remanufactured starters before. The ones ford sells are remanufactured even though they say they are new.
