I have replaced both O2 units, fuel filter and can get the engine to start and run after a squirt of starting fluid. Will not start on it's on. We were driving it and it killed and has not started on it's on since.
Do you

Hi jay reed. Welcome to the forum. Will the engine start and run if you hold the gas pedal down about 1/4"? If so, was the battery recently disconnected or run dead? That will require the Engine Computer to relearn "minimum throttle" before it will control idle speed. Until them, idle speed will be too low and the engine will typically stall when pulling up to a stop sign.

Yes I did remove the battery cable to try to reset the security system to see if that was the problem. How long will it take to relearn the idle speed?

The relearn procedure is real complicated but I think you can handle it. Drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the brake or gas pedals. That's it.

The signal for the computer to do the relearn procedure is high manifold vacuum for seven seconds. The only way that can occur for that long is by coasting. That also tells the computer that your foot is off the gas pedal and the throttle position sensor is reading the lowest it ever will. The computer memorizes the voltage from the sensor at that point. From then on, whenever it sees that same voltage, it will know it must be in control of idle speed.

Sorry for the delay in replying. My Verizon e-mail system keeps going down, often for a day at a time. Without e-mail, I can't get the automated messages that direct me to your last reply.

Thank you very much for the information. I got it running and it seems to be doing fine. My wife drives 2.5 hours one way to work in Fort Worth Texas and then sits in traffic. It has done well so far this morning. Thanks again!
