Question about 1994 Ford Thunderbird
You need to run a quick test on the engine control computer. You may also just have a defective electric fuel pump inside the fuel tank.
This will reveal any fault codes that might be present. Follow the instructions at the link EEC IV Self Test Ford Fuel Injection and EEC IV Electronic Engine Control...

Check the ignition module (located in distributor, under cap). These modules not only control ignition firing but also send a signal to pcm to control fuel injectors. They can become heat sensitive and fail intermittently. Most auto parts stores can check these modules if you remove and take them in.

Best do a fuel pressure test. Should have chg. fuel filter from the get go. The only other filter is on the end of the fuel pump in tank. Bad gas and dirty gas will plug up fuel filter, hense burn pump up.

95-97 Maximas had a problem where condensation from the A/C would accumulate in the a/c evaporator case from the drain becoming restricted or blocked, When this would occur, condensation would drip onto the ECM and a problem would develop with misfire and/or starting. I would look at the ECM where the harness connects to it for corrosion problems. If you find it, there is a chemical spray which can be used to clean the terminals and/or you can clean them, although it is time consuming and difficult to due because of how small the terminals are. After things are cleaned up, lightly coat the connections with a dielectric grease. This will prevent electrolysis.I believe you can buy these at Radio shack and possibly at an automotive parts supplier.
Also a drop in voltage during the cranking phase will cause a weak spark. Your ignition is what pulses the injectors. It takes a minimum of 9.6 volts, but ideally you want at least 10.5 or more during the cranking phase if you want to get a spark worth anything. Check the voltage on the primary side of the coil while cranking the engine.
I'll watch to see if things work out for you, let me know. ....mybunkey

SOURCE: I have a 1991 Dodge Stealth ES that will not start or run unless I spray brake cleaner into the throttle body. It has no injector pulse, good fuel pressure, and has spark. Have had the computer rebu
