Exclamation Need Help!

I have a 94 mustang gt, and it keeps dying on me. My husband is a really good mechanic, but mostly works on Chevys, so he's kind of stumped on this. We have replaced the ignition module, the distributer cap and all spark plug wires. He says it's definitely not the fuel pump.
She only wants to run when she's cool. I drove her a couple miles and she died last night. Wouldn't start again. Husband says she has "no ignition". If anyone has any suggestions, it would be greatly appreciated! Thanks!

It is more than likely the TFI module, highly doubt it's the coil.

Thanks for the help! I guess the TFI module is what we replaced last night, so it's on to the coil. Great feedback!

I had the same issue 2 different times 2 different problems, first time it was the "coil pick up" if you order it through the parts store that's what they call it, just the wiring from coil to distributor. But you will need to tear down the, distributor fully to replace because it slides around the shaft. Fixed my problem first time....next time was a month later, thought it was fuel pump because I couldn't hear it,humming and no fuel...but after testing it it was fine...the problem was actually a,simple fix of dirt and grime in the connection to the top of the pump, cleaned it and got a good connection, haven't had the problems anymore 7 months later. Hope it helps.

The PIP would be my recommendation too.
They act up just like you are describing. Run fine when cold, won't run when hot.

+1 PIP. Pull the distributor and check the wheel too.

Re: Need Help!

P.S. If the engine has a lot of miles on it you may be better off replacing the entire distributor as it is likely worn out anyways.
