Does it have fuel pressure? Did you try unplugging a couple injectors and then try to start it?

What style distributor is it? Is the TFI Module on the distributor or on the passenger side fender apron?

94-95 distributors had a common problem with the PIP sensor (distributor pickup sensor) inside the distributor going bad. If you do replace the PIP, use a Motorcraft/Ford piece, part number DU50.

“When gets hot”…. How hot is hot, what is the actual temps you’re seeing?

“Stock computer” meaning the stock J4J1 for a 94-95 Cobra, or has someone swapped in an A9L, or swapped in a 94-95 GT T4MO or other other “5.0” computer?

You have to give us more than bits-n-pieces here.

How modified is this car, what is on it?

You’re saying it’s a 95 Cobra but has a “Fox motor”…. To me, it sounds like the car is no longer stock and has been modified… and just an FYI, a 94-95 SN95 5.0 (Cobra or GT) is still on a Fox platform (floorpan/chassis) and is still the same basic “5.0” found in the prior 86-93 EFI H.O. Fox.

What’s the timing at (spout in)? What’s the spark plug firing order that YOU have?

What MAF is on it - stock, aftermarket, A9L, or factory 94-95 Cobra or factory 94-95 GT and what’s the sensor calibration?

The T4M0 is not a 1994-95 Cobra computer. That belongs to a 1994/95 GT.

Therefore you MUST make sure that the MAF sensor is calibrated to the fuel injectors that are in that engine.

Also 1994/95 5.0 firing order is:
1 3 7 2 6 5 4 8

Which should be the same on a pre-94 Fox 5.0.

Also as was noted previously, the 94/95 5.0 distributor is specific to a 1994/95 Mustang 5.0. You can't use a pre-94 5.0 distributor OR TFI module in a 94/95 - the circuitry is different in both units.
