Electrical problem or something else??

10-09-2001, 12:33 PM

My car will start fine and run. However after I get to my destination, and shut it down, I won't be able to start it again for anywhere from 5 to 20 minutes. This is particularly aggravating when I pull up to the gas pump, get gas and then my car won't start again for a while. When it finally starts, it seems to run fine. This isn't an intermittent problem. It does this EVERY time. I have replaced the TFI module, plugs, wires, fuel pump, pump relay, the cap and rotor are not old at all and appear to be just fine. When it doesn't start, I have spark and fuel. The motor just turns over but doesn't fire up. It seems that something is heating up, and has to cool down before it will work again, but I don't know what it could be. Any ideas?

check the coil. when it happens again, wiggle the wires on the coil. i replace many ford FI coils. alot of times the connection inside the coil goes bad.

You only need four things for an engine to run:
Fuel
Air
Spark
Compression

I suspect your coil is weak. How bright is the spark when you check it?

Okay, I replaced the coil with an MSD coil and installed an MSD 6-AL. There is no change whatsoever. I can start it up and let it run for 25 seconds, then shut it down and it won't start again for maybe as long as a half an hour!! I am lost. I tried to pull the codes from a KOEO and it gave me 10 freakin codes!! 51, 22, 53, 54, 35, 67, 81, 82, 85, 95. I was thinking that since it gave me so many codes that maybe my ground is bad, but I have a huge grounding strap from the firewall to the bellhousing. Where does the EEC ground?
