Vehicle will start but dies shortly thereafter. CONTINUED
What is your question?
I spoke to my stepfather who is a master mechanic and been one for 40 years...
He is the one that has done 99% of the work on this. But unable to figure out the problem.
Crate Motor 40k
Rebuilt S/C 10k
All new Main Fuses/Regular fuses
New Fuse Boxes
New Computer
New relays, Sensors, Sending units, Etc.
As he tried to fix the problem, he would replace everything.
New Fuel Pump replaced inside the Fuel Tank.
Car starts and will run great up until it hits running temp...
Then begins to pop, sputter and acts like the timing has been retarded then dies...
Wait 10-15 mins. - Car starts up again and runs great.
We have had the vehicle to 2 different dealers and left for several days each time.
Spark plugs and wires have all been changed and double checked to make sure snug and no shorts.
Any ideas on this?
Does anyone know of a mechanic that specializes in the
90 T-Bird Super Coupe?
Please don't hesitate to ask further questions... This has really been a pain...
Thanks,
Ron

Has a *professional quality* scanner been used for diagnosis? .. Including live data parameters viewed while engine is cold, through the warm up cycle? .. Fuel pressure test with proper testing equipment? .. Complete ignition system testing? .. The information about what parts that have been replaced is actually irrelevant! .. Troubleshooting has to be done in a systematic sequence as opposed to random parts replacement to see if that fixes the problem... Furthermore, if this issue has a mechanic of 40 years stumped then about all we can do here is guess at it and that doesn't help .. *Hands-on testing* is going to be the key factor in finding a solution by proving what the trouble is... Good luck with it!
I agree with you completely. As the vehicle was down in CA while I was in WA, I would like to think the dealer while he had the thing for a week each time would have done jut what you are saying but who knows.
Thank you for your time. You never know when someone has had the same issue and has an idea...
That's true, it never hurts to ask!! .. I hope someone can add some useful information for you .. There are just too many possibilities! .. Another very good piece of diagnostic equipment for this vehicle is an older designated oscilloscope, if you can find a shop that has one, and someone that knows how to use it!
