Being 94' im sure it has high miles, cam and crank sensor common to fail over time do to wear and heat exposure. check the basic, make sure you getting fuel and sparks. fuel pump only work as long the engine is turning over due to the crank sensor sense the flywheel turning. crank sensor may be faulty. no sparks, check coil make sure is good and putting out 12v, auto zone can test it for free. good coil, than check cam sensor, cam sensor senses the cam turning and tell the ecu to tell the coil to disperse the sparks to the plugs. cam and crank sensors, there no way of testing it but replacing the unit unless you have the special equipment to test it; both is fairly cheap to replace, check ebay.

Why wont my car start after replacing the fuel pump


Do you hear the fuelpump running? Check the Inertia switch under the right front passengers kickpanel. There is a button to press and it will reset.

This is a safety switch for impacts and when the fuelpump was disconnected, it can sometimes trip.

Also, when you diagnosed a bad fuelpump, there are Relays and fuses which supply the power. Your original problem could have been a bad relay.

Truck starts runs for a second shuts off .


The fuelpump is primed by the oil pressure switch.When the fuel pressure reaches normal PSI the computer shuts that pressure switch off and turns thepoweron to the fuelpump relay.You have a bad fuel pump relay

TRY REPLACING THE FUEL PUMP RELAY. THIS SHOULD SEND POWER TO THE PUMP. IF NOT, THEN CHECK THE WIRING HARNESS NEAR THE FUEL TANK. I HOPE THIS HELPS. P.S.: IF I REMEMBER CORRECTLY, THE PCM IS RESPONSIBLE FOR THE FUEL PUMP OPERATION. THANKS FOR USING FIX-YA. PLEASE KEEP ME POSTED. GOOD LUCK

1996 mazda mx6 ls cranks but won't start


you may need to run a wire from a keyed ignition source that has power while cranking and running to the fuel pump relay and bypass the pcm to test wether it will run, if it runs put a more permanent wire in place.Not too sure what tests youve done but it seems that fuel is what your focusing on so a quick test is too spray engine start up the intake tube to see if the engine trys to run if it does it eliminates a lot of other potential reasons for a no start condition.Also try squeezing the fuel return line to see if the added pressure will try to make engine run.Could be time to replace fuel pump etc anyway let me know how it goes good luck with it
