So we have a 1994 Ford Mustang 3.8L V6 Manual trans. It has not ran since the day we bought it. Previous Owner thought it was the fuel pump but it has good fuel pressure so we ruled that out. Replaced spark plugs and wires, and noticed the spark plugs were flooded with gas so we replaced the mass air flow sensor, engine computer, and both oxygen sensors. Still no difference the engine will turn over but will not start. We can get it to run for a minute if we keep it revved above 1000 rpm's but after that it dies. Any Ideas what could be wrong with this car we're running out of money to keep guessing at parts and we're getting a little frustruated. any advice or suggestions would be helpful thanks.

check the crankshaft position sensor. does the car have a distibutor or coil pack?

Sounds like it could be a crank position sensor like above, but have you done a compression test on it yet?

We replaced the crankshaft position sensor and the throttle position sensor on top of what we already replaced and still no luck and it's coil pack. we are basically just replacing one sensor at a time trying to get lucky but are running out of steam. We got it to run before but it wouldn't accelerate over 10mph we had it up to 30mph then it died and now it wont start at all it's backfiring in the intake and the exhaust

and yes we've done a compression test and it was normal

Sounds almost like the cam timing is off, but I don't know how that could happen unless it's been taken apart and then put together incorrectly.

Maybe I'm being dumb, the '94 had PATS right? If so, swapping the computer worked against you and it won't start due to the key not matching correctly. Go back to the stock computer.

Check your coil pack.
