Your throttle is "fly-by-wire" which means that it is completely controlled by the computer. There are several switch and sensor inputs and an output circuit to the throttle actuator motor.

Both your gauges and you Idle Validation Switch are protected by fuse #19 (10 Amp) in the Central Junction Box, which is located at the lower left-hand side of the instrument panel. There are a lot of things also protected by this fuse including the Generic Electronic Module (GEM). There will be a lot of things malfunctioning if this fuse is blown. This fuse gets its power from the ignition switch.

I would start by checking this fuse to (A) see if it is blown and (B) Make sure that this fuse is receiving power from the ignition switch. If it is blown, it will do no good to replace it until you can locate and repair the reason that it blew. If it has no power, you may have a bad ignition switch and/or a burned connector at the ignition switch.

Please also review these articles: Where's The Fuse? What Else Could Be Wrong?

If this does not turn up any problems (i.e. the fuse is OK and is getting power from the ignition switch) I would scan both the GEM and the Powertrain Control Module (PCM) for fault codes before even trying to perform any further diagnosis or attempt any repairs. There will most likely be fault codes present and/or the GEM may refuse to communicate with the scanner, either of which will help to determine the game plan for getting this problem resolved. Since the engine starts and runs, The PCM is not likely to have non-communications problems, but it can also report engine management system faults or communications problems with other modules. If the GEM is working, it may tell you if there is something wrong with the PCM. So, it is imperative to scan both for a complete diagnosis.

Pull the pre O2 sensors( it will be loud). If it stays running longer, replace the catalytic converters.

1995 ford 4.9 stright 6 runs for a couple min then dies


The parts you replaced don't typically fail due to heat/cold cycles.You need to see if it might be the ignition coil.Make the coil easily accessable(take of the engine cover).Have a 12v test light and some sort of spark tester handy.Start the engine,let it run until it quits.See if you have spark at the coil.If not, unplug the low voltage connector on the coil,and put the test light across the connector,and crank the engine.The light should flash on and off.If it does,replace the ignition coil. If it doesn't flash,you may have a bad crank sensor,but this usually won't make it shut off,instead,it will cause it not to restart after heat soaking for a couple minutes.(I'm betting on the igniton coil).

Try getting your transmission solenoid replaced. After I got mine replaced it ran fine after that. That's the exact same thing my Lumina was doing.

Engine shuts down


The only way to know for sure is to hook a gauge to the rail and check the fuel pressure when it won't start.
Sitting for a few minutes and restarting is normally a sign of a relay or coil cooling off.
There should be a EEC relay that powers the dist module and ECM.
I know you said you have spark, but it could be something else
related.
Also, if you have spark at the right time and no fuel pressure, you should be able to use starting fluid to substitute.
I don't suppose you have dual tanks and the switching valve is the problem ?

Car runs great until it get about 180 degrees andthen shuts off let it cool off a lil bit its starts back up until it shuts off again why


I am thinking that perhaps the temperature sensor is reading wrong and therefore sending a message to the computer that the car is running too hot. This can happen, my VW presently reads 20 hotter on the guage than a heat gun records at the temp sensor location on the head. If you have access to a heat gun it might be a good idea to check out the actual temperature, but it probably won't hurt to change the sensor.

The other problem that occurs to me is the oil sending sensor. While a temperature sensor won't shut an engine down, the oil sender can. If it is reading a large drop in oil pressure it will shut the engine off. Since oil gets thinner as it gets hot, perhaps a defective sending unit is reading it as too low. Once the oil cools off, it would restart until the temperature gets too high again. I would think that upgrading to a heavier oil might cure the problem. I don't know what you are currently usung but certainly you could go to 10W30 or 10W40 without too much trouble, at least for a test. Hope this helps.
