The following are the general instructions on the start of diagnosing any electronically controlled engine or transmission problem.

The engine and the automatic transmission (transmission control is only for automatics, engine is still computer controlled no matter the transmission type) in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. There are exception to this, such as the Mass Airflow Meter and fuel pressure problems. What must be done is to have all the basic testing done such as a scan of the system for fault codes as well as a check with a live data scanner tool for engine functions that are not within range of normal, a trained technician is required to know what is correct and what isn't, then based on careful diagnostics done from a factory repair manual the correct part is replaced or the wiring repaired or the computer replaced (known as the PCM or ECM,ECU), which is very rarely the problem. Other basic checks must be done as well such as mechanical problems with the engine as well as engine state of tune and mileage on the engine. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. Also engine mechanical problems can and do cause many drive-ability related problem such as rough idle and other symptoms.

SOURCE: won't start unless you push

it sounds like fuel pump is going. pressure should be around 40 psi.
Or it could be flooding. Holding gas pedal to floor during cranking of the engine, shuts off fuel flow through the injectors to clear a flooded engine. After engine is running again, it lets fuel flow.

If you have a Mass Air Flow Sensor in the iar intake tube, clean it with spray carb cleaner several times.

Also, try disconnecting the oxygen sensor to see if it helps. It will turn your check engine light on, but you can cycle key from off to "on" 40 times to turn it off.

SOURCE: 1999 ford explorer starts, but will not stay

SOUNDS LIKE THE IDLE IS TOO LOW! YOU MAY NEED TO IDLE IT UP JUST A LITTLE! YOU CAN EASILY DO THIS AT THE THROTTLE PLATE UNDER THE HOOD! THERE IS A SMALL BOLT, OR SCREW LOCATED ON THE BACK SIDE OF THAT PLATE! TURN IT CLOCKWISE, AND IT WILL RAISE THE IDLE!

My 2005 Ford Focus won't stay running unless my foot is on the gas. It starts just fine & the check engine light is NOT on. What could be causing this?


It is likely that the engine management system has lost its base line calibration. If the battery is weak and during the crank to start the voltage dipped low enough the Engine Control Module lost its calibration. If the pedal is depressed during the crank the TPS (Throttle position sensor) will lose the idle position for the throttle. The hunting and surging and resultant stalling is the ECM seeking out the limits and re-establishing the throttle idle plate location.

If battery is OK than running the car allowing the calibration of the vehicle to reestablish itself will correct the problem. My experience is that this happens if the gas pedal is depressed during crank with a very very low battery voltage. Always the best way is to not touch the pedal during any cranking starting procedure. Or after a battery replacement.

To accelerate the calibration process attempt to run the car ingear tring not to allow the car to stall. After afew munites the car will have reestablished its normal running calibration and you will be allset.

My 2001 ford crown victoria won't stay running unless i hold my foot on the gas


A few different things could be going on here. Some things to check: possible vacuum leak, TPS (throttle position sensor), IAC (idle air control valve). I would check these first. Is the ck engine light on? If it is, take it to your local O'Rielly's or Auto Zone, they will scan it for free. Hope this helps, TJ

Wont hold idle will start with foot depressing gas pedal will run with foot on gas but stalls when foot removed


Check and clean Idle air control valve. Make sure its responding to signal as well. Also make sure ther are no vacuum hoses disconnected. This may not be a "cure" but it's a good place to start.
