Will a bad crankshaft position sensor cause the fuel pump not to get power to it ?


Crank sensor is for spark, cam is for fuel timing. Fuel pump is bad fuse/relay or pump. Year make and model?

2000 Kia Sadona...Stops from time to time. Usually when coming to a stop or taking off. Replaced fuel pump. Sometimes difficult for engine to turn over. New battery. Once I moved electrical connector...


Sounds like a possible crankshaft position sensor. It is located behind the harmonic balancer, inside the timing cover. It sets by the timing belt, so if you have a loose timing belt it could hit the crank sensor or throw up pieces of itself onto the crank sensor. A bad crank sensor can mimic a fuel pump issue. 721c6cee-d9f3-4086-a166-f472fa0318af.gif

1989 ford escort turns over but wont start


if all you did was this...and and put a new battery in and still wont start...if you have went thru your plugs..wires..distributor..ignition coil...made sure your getting spark..if not..check your relays and fuses..preferebly one that deals with spark and timing for injectors..if everything is fine to that point...then try a crankshaft position sensor...it tells the pcm timing for fuel injectors and fire to the ignition coil...hopefully this helps.

replace fuel filter.listen for fuel pump operation with ignition switch on position for 3 seconds should hear fuel pump running should have humming or churling noise if so fuel pump working if hear no noise fuel pump faulty or could have blowed fuel pump fuse or bad relay.if fuel system okay problem could be ignition timing off due to worn broken timing belt.could have faulty ignition module.bad crankshaft sensor or camshaft sensor best to have vechicle code scan first before buying alot of new parts.could have bad ECM. many things will cause no start problems i.dont know model type vechicle.could have bad spark plugs wires. distributor cap and rotor could be bad.ignition coil could be bad.

Engine will crank but will not start and run.


Change the fuel filter first! It is located on most models passenger side center to rear center of van & tucked up near frame rail. Good luck!
