Holding the gas pedal to the floor puts the computer in "clear flood" mode - that is the computer "thinks" that the engine is flooded, and shuts off the fuel! No fuel, no start!

Try this: do nothing more than turning the ignition switch. First, turn the switch to the "ON" position. Listen for the fuel pump. When the pump stops, turn the switch OFF. Then turn the key to the ON position, and after a second or two, turn it to the START position. Do NOT touch the pedal! Turn the key ONLY!

If this does not improve the starting, you need to check for spark and fuel pressure. But first, try it out as I have instructed. Post me with results. I will then try to instruct you further in diagnosis.

It still will not start, it has fuel pressure and fire, all plugs and wires are good. Fuel pump is coming on and working properly also. It still will not turn on

Start by checking under the distributor cap. See that the rotor is in good shape, and has no carbon tracks on it. If there is any doubt, replace the cap and rotor. Check to see that the rotor is actually turning when the engine is cranked.

Keep in mind that the engine needs THREE things to run:

1) Compression
2) Spark - and at the right time and place.
3) Fuel and air mixture.

One of the three is not as it should be. There are many possibilities. I'll try to work you through the most common ones to begin with.

Does the engine sound normally when you are cranking it? If not, then a compression test is in order. A timing chain could have gotten loose enough to affect your valve timing. A compression test will show this.

Is the distributor rotor turning evenly? I have seen the gear on the distributor "apple core" and not fully engage the drive gear. This will cause the ignition timing to be wrong, and will cause the engine not to start.

Check throttle position sensor voltage. The sensor is located on the throttle body opposite the throttle cable connection. Without unplugging the connector, probe the GRAY wire with a YELLOW stripe. You can do this by inserting a straight pin into the connector alongside the wire. Check voltage to engine ground with a digital meter. With the ignition on and engine not running, and throttle closed, the voltage should be from.75 to 1.0 volts. Any higher indicates a bad sensor, and is turning off the injectors while you are trying to start.

This should get you started. Once again, post back with results, and if necessary, we can continue.

I took it to the shop today when it left me stranded in the middle of dropping the kids at school. The mechanic said its some temperature sensor thats bad and is making the car flood or something to that sort, I dont know but I hope he is right cause as the single mom of four I dont have the money for him to be wrong

I put a new inegrated relay control on the car but still will not start. When you turn the key on the integrated relay makes a humming noise the old made the same noise The car turn over but will not start.

Hi var508, Welcome to 2carpros and TY for the donation

You probably have short circuit somewhere affecting fuel or spark-do below and let me know

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, Do you hear the fuel pump come On when you turn key on? If not check fuel pump fuse and fuel pump relay if so, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, cap and rotor, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it and keep testing

GOTTA START SOMEWHERE

OTHERS MAY JUMP IN AN HELP

ANY RECENT HISTORY....NOISES....CHECK ENGINE LIGHT....OTHER?

WILL IT TURN OVER GOOD?

DO YOU HEAR THE FUEL PUMP "H.UM" FOR A SECOND OR TWO WHEN THE KEY IS TURNED ON?

DO YOU HAVE FUEL?....STUPID QUESTION....SOMETIMES OVERLOOKED

SEE IF THIS HELPS

THIS TIME LETS HEAR EXACTLY WHAT MODEL TAURUS YOU HAVE AND ENGINE SIZE

NEXT THINGS WE NEED TO KNOW IS, WAS YOUR CHECK ENGINE LIGHT ON?

THEN THE NEXT IS....DO YOU HAVE SPARK?

I TRY TO MAKE THINGS EZ ON MYSELF (I'M USUALLY THE ONE TO GET NAILED BY VOLTAGE, EVEN IF I'M THE ONE STANDING THE FURTHEREST AWAY!!!

I HAVE ACCUMULATED FIVE OF THESE OVER THE YEARS, I KEEP TWO IN EACH JEEP (LIKE MY NAVIGATION COMPASS, I HAVE A "BACKUP" JUST TO LET ME KNOW THE OTHER IS FUNCTIONAL, PEACE OF MIND....IMPRESS OTHERS!)THEY WORK VERY WELL, ARE REALLY INEXPENSIVE, COMPACT, QUICK TO INSTALL AND GET RESULTS----IF IT'S REALLY SUNNY, "ARTIFICIAL SHADE" HELPS TO SEE IT BETTER. OR YOU CAN DO THIS THE OLD FASHION WAY, SHOVE A NAIL OR SIMILAR INTO THE PLUG BOOT AGAINST THE METAL INSIDE, HAVE SOMEONE "CRANK" WHILE YOU HOLD THE WIRE W/ NAIL ABOUT A 1/4 INCH FROM THE MEAL OF THE ENGINE.

EVEN THOUGH YOU MAY HAVE NOT HAD AN INDICATION OF A CODE, DO YOU KNOW SOMEONE WHO MIGHT COME TO YOU AND CODE IT? FAMILY, ACQUAINTANCE, ETC?....I HAVE TALKED AUTO SALVAGE YARD GUYS AND AUTO PARTS STORE FELLERS INTO STOPPING BY, AFTER THEY GOT OFF WORK IN THE PAST (TIPPED THEM WELL), PRIOR TO ME OBTAINING A SCANNER OF MY OWN.

I'M DOWN HERE IN S.C.--IF YOU MIGHT HAPPEN TO BE CLOSE TO ME, I'LL SCAN IT!....JUST GETTING YOU PREPARED, IF NEED BE

ANYWAY--GOT YOUR MISSION RIGHT NOW...SEND RESULTS

LETS ALSO POP THE HOOD AND POUR IT OVER WELL, LOOKING FOR LOOSE STUFF, BURNT STUFF, CHECK THE FUSES

USING A VOLTMETER WHAT IS YOUR BATTERY VOLTAGE?

IF NOTHING ELSE, DO THE HEADLIGHTS SEEM TO WORK WELL FOR A FEW MINUTES?

Replaced ignition modual- wont start. Fuel pump not getting any power. Cannot connect to computer for trouble codes. Couldn't find any apparent wiring problems. Not sure where to look next without replacing parts. Other than above issues everything works fine.

You need an ohmmeter-the relay has a coil and a switch side -the coil side should read between 40-80 ohms and the switch should read infinitive-try swapping it with a like one

I have replaced the head gasket and plugs and wires and once back together it will not start. Compression is good, sparkplugs fire and it still wont start
but I did break 2 fuel injectors and was wondering if that would cause the car not to start at all I mean it doesnt even try. Thanks for any help
