Have 2005 accent no power to the fuel pump. fuel pump works fine when supplied with power, even with fuel pump running engine cranks but will not start. Fuel pump receives no power from ign. at any time.

NO ENGINE TOLD AT ALL.
it does not work like you think
is engine dead, that it, no symptoms told at all zero ,

rreirr>>?????? (repair?) first off does starter crank the engine?
the ECU only runs the pump cranking, (on dead engines)
this prevents crash and burn by law,.
most cars cut injection and pump power if the PCM sees
spark detected dead, or its precursors CMP/CKP
or RPM dead. by laws, and is for safey of you and other.s
fuel must not be pumped ever at dangerous times even SRS air bags errors or deployments.
to do your trick at pump pins.
1: fuses all good
2: person 1 cranks while person 2 checks pump voltage if 0volts
that means the PCM is not happy (or relay fuel bad sure)
ok this fails, a legit test. we do what.
enter now the SCAN tool OBD2,.. connected,
3: then we crank for 5 seconds while cranking and see OMG errors
that cut fuel dead, on all EFI cars from 1990 to now, 32 years, sames story, same laws same safety features.

the key on , engine not running the pump is dead.
by law and not anything bad, but by pure DESIGN.

OR OMG EASY
SCAN TOOL CONNECTED, AND SCANNED KEY ON NOT EVEN RUNNING AND YOU GET DTC ERRORS p03XX FOR CMP
THE CAM BELT BROKE OR SLIPPED, AND CAR DID NOT CATCH FIRE. ,,,,,,,AMAZING.
BUT GEE NO ENGINE TOLD OR VIN TOLD SO i CAN TELL YOU.

OR WATCH SCOTTY kILMER, so cools is he, love him.

If you invested all the money you've spent on parts, you could have paid for a qualified technician to troubleshoot and repair your problem, and have only paid for parts you needed. Now you want someone who may have no qualifications, and no opportunity to even see the vehicle, to troubleshoot your unresolved problem. LOL

older post no engine told.
IT does crank and does start and then fails but pedal pump keeps it going (well vast causes ) here is short list./
that is bad ISC. ,stuck closed , causing no idle air supply.
or EGR stuck open.
sPARK PLUGS BAD.
SPARK COP COILS BOOTS BAD, RUBBER. AND CARBON FAILED.
BAD FUEL
INJECTORS WEAK OR LEAKING (WE DO FUEL PRESSURE BALANCE TEST TO FIND THAT)
BAD ENGINE? (a large list for that) even bent head valves.

how well the pump pedal works we can not guess and MATTERS HUGE>?

You need to scan the ECM to see if there are any stored DTCs. Just guessing, it sounds like a bad cam or crank sensor. They can be temperamental when they get warmed up, if they are bad.

You need to be very quiet for this test, but try turning the ignition key until dash warning lights are on, but without cranking the engine. Listen for whirring noise from fuel pump in the gas tank. You may even lift out the rear seat base, to pick up any sound as best you can. If you can't hear anything from several attempts then it's likely you have a failed fuel pump. The fuel pump can sometimes suffer damage when running out of fuel.

Have you checked the timing belt, it is most likely has stripped out teeth and not turning the camshaft(s). Pull the belt cover off the front of the engine and see if the camshaft pulleys rotate when cranking the engine over.

Take one of your spark plugs out and look at it. If it is wet then you have a spark issue....

If it is light gray and dry then it is a fuel supply issue....

Check that out and let me know what you find.

built in the black bulb pump is a non return valve.That is not working so enables the fuel to run back.They are quite easy to get from your local auto spares shop.

Have somebody cycle the key on and off and see if you have power not cranking the engine just from the off to on or run position. If no power, check your fuse for the f/p and the coresponding relay. bet way to check fuses is with a test light. Most times a power window, a/c or heater relay will be the same and you can switch it out to see if it solves the problem. mike
