Question about 1994 Ford Thunderbird

2 Answers

WHY does a 1994 Ford Thunderbird LX V6 3.8L not start after it has been running for a while? Example: drive to store, come back after 20 minutes and car will not start. Sit there for about 20+, then car finally starts. Put on diagnostic test = only need distributor (replaced and still doing the same thing)

Fuel pressure regulator might be the problem, the diaphram ruptures and the regulator leaks gas into intake, causing the engine to flood. Try holding the gas pedal to the floor while your cranking it. An easy way to tell is pull the vacuum line off the fuel pressure regulator if it's wet with gas or smells like gas that's the problem. It should be on the fuel rail, on top of the engine and looks like vacuum advance unit only smaller.

Sounds like your ignition module is bad. Its located on the passenger side inner fender mounted to an aluminum heat sink. You can take it to an auto parts store and get it tested for free. When they get hot, the car will not start. When it cools off, it will run fine. Eventually what may happen is the car will die while driving. Net time this happens, put your hand NEAR it but not touch it. Should be really hot. Using a damp rag, you may be able to cool it off and start it faster. Eventually, it will need to be replaced. 1 other thing, is you have a ick up inside the distributor. Since you repalced the dist. then this should already have been replaced. When replacing the ignition module, make sure you get the grease for it.

Thunderbird Starts Fine and after say 25 min drive on the highway. pull into lets say walmart run in back out and the car struggles to start bucking and such and usually stalls and wont start.. after it...

Sounds as if you are experiencing early stages of fuel pump failure. The pump motor is getting "hot" during the 25 minute drive. After you shut the car off and try to restart it,the pump is weak and not getting the fuel pressure up enough to allow for a quick start and smooth running. I would check the bleed down time on the fuel system and the pressure to see what it is before and after the 25 minute drive time.

What I have is 1997 Ford Thunderbird, a code comes up p0174? Can you help figure this issue out.

garyq1970 ythose are called DRIVE-ABILITY ISSUES,

As far as the code P0174 goes 1st check for vacuum leaks, use a can of carb spray to do this test, if the engine RPM changes (increases) while spraying then there is a vacuum leak and this will cause the code, while u are at it clean the Mass Airflow Sensor, the spray cleaned is available at any good parts store it is made by CRC chemicals.
My knowledge base? 20 years as a Ford tech and 10 as a Ford factory certified Master Electronics Technician.
