Engine is stalling out while driving

Usually the problem isn't a bad PCM, but rather a bad connection within the wiring harness where it plugs into the PCM. I may have already asked this, but have you check the connection where the wiring harness plugs in to the PCM? I have seen corrosion, bent pins, or loose connections cause problems.

Let me know.

Ok lets see what we can do some things are harder to do long distance then others so you may need to be patient ok. I need to know when it dies is it spark or fuel that is missing? As for the guages we will get to that later ok. THe ground wire that you replaced what did it go to? Do you have a digital multi meter you may need to do some tests. Get back to me with what you know and we will go from there. Thanks and have a great day.

Ok that was a ground strap for the body to hood thats all nothing more so that should not have had anything to do with it. Now what I need you to do is pull a spark plug wire off and put a screw driver in the end of it just (a philips works best) and put it near metal and turn the engine over and see if there is spark or not ok. Get back to me with what you find. Thanks

Ok what you need to do it disconnect the connector to the coil and I need you to use a digital multi meter and check for voltage at the B poss term at the connector the wire to that on the connector will be Dk blue and Tan. Here is a pic of the connector ok. Then I need you to check resistance between term 3 and the B poss term the first should be battery voltage the second should be 2 ohms of resistance or more. Let me know what you find ok. Here is a pic of the connector.

If this checks out ok then we will test the Auto Shutdown Relay ok. Thanks and let me know what you find.

Ignition switch, Idle speed motor, engine computer, crankshaft position sensor, electrical connectors, automatic shutdown relay, MAP sensor, EGR valve, throttle position sensor, air conditioning over-charged, etc.

WAY too many things to guess at without more information, but a fuel pump and tune-up are two of the least likely causes. When does it stall? Driving? Idling? Coasting? When coming to a stop? Does anything else stop working? Was the battery disconnected recently? Does the "Check Engine" light come on while driving? Will it stay running if you hold your foot on the gas pedal?

Fuel pumps USUALLY cause a no-start. Tune-up issues will cause a surge or sputter.

MAP sensor reports engine load. It can be incorrect without being out-of-range. That will result in the wrong amount of fuel being delivered. Crankshaft position sensor can be intermittent, but they usually have to cool down before they will work again. Burned contacts or connector pins in the ignition switch will also cause the radio display to go blank. Idle speed motor can let the engine die when coming to a stop if the computer doesn't know minimum throttle. That information will be lost from memory if the battery was dead or disconnected, but it will not cause stalling while your foot is on the gas pedal. If the heater control lights are flashing, battery power was lost. That computer will need to be recalibrated, and minimum throttle must be relearned. Minimum throttle just involves driving it under a specific set of conditions. This doesn't sound like your problem.

Holler back with more details.

Has the Check Engine light come on while driving? A good suspect is the crankshaft position sensor but it would be nice to have a diagnostic fault code pointing to that circuit rather than just throwing random parts at it.

1st check for codes
check fuel pressure '
check for vacuum leaks
