Wont pump fuel /has new pump works sensor fuel and every thing you need has my sparky stumped and its a common problem what is it

Remove mass air flow sensor Clean and re-set connector to it. See if that helps. Worked on my 94 4.0.

could be a number of things this one....immobiliser problem, fuel pump etc etc. I`d try basic stuff first like checking the sparkies are doing their job and take it from there. has main starter relay gone perhaps?

Some cars have a safety shut down fuel pump relay,Have you hit a big bump or had a fender bender? Oil pressure sender will stop the pump,is the fuel filter plugged,Have you cheked the fuse, is there power to the pump? Is the tank empty? Is there power to the injectors? Engine computer?

Did you check your fuel pump relay? Also make sure you connected all the plugs on the sending unit properly

Go back to basics---3 things needed to make an engine run---fire/spark---gas/fuel----air---remove anyone of these and the engine will not run---have you checked for spark when cold----you've tried fuel from what you've said---is there any type of damper that opens and closes when cold---possibly operating a switch/sensor when closed/cold in conjunction with something else---another idea is possible that when cold something (electrical connection attached to metal housing) is contracting loosing contact---corrosion issues with connections---this all has to do with spark that may change with temperature---find out what you don't have (spark-fuel-air) and go from there GL

PROBLEM COULD BE THE WIRING, CHECK WIRING HOOK UP.MAKE SURE WIRING CONNECTIONS IN PLACE GOOD AND TIGHT MAKE SURE FUEL PUMP GETTING GROUND.IF WIRING OKAY.EITHER CAR HAS PCM PROBLEMS.

Power loss can result from dirty air filter, plugged fuel filter, and excessive spark plug gap. Check these things and if stilll stumped get back to me.

make sure the points in the distributer are lined up and check the condition of the cam sensor and crank sensor

I'm assuming the engine is cranking over while turning the key and wont start. from this assumsion it possible the cam sensor on the timing chain is broken. or no fuel pressure. to test for fuel pressure, turn the igntion key on, locate the fuel line & port on the fuel line, remove the cap & depress the small screader valve by using a small pocket screwdriver, fuel should shoot out with a lot of pressure. no fuel shooting out most likey the fuel pump is bad. if this has good pressure the cam sensor is most likey the cause. to replace the sensor, you need to replace the timing chain.

It could do that with a bad switch if it was making poor contact before it disconnects, but that really sounds a lot like the fuel pump is going bad...they overheat and start to bind up, then stop...once cooled down they work just fine till it again gets hot enough to do the same thing all over again. I really hate doing this online because in real life, I'd be doing tons of testing instead of making "educated guesses"
