i would check wires at plug and the plug itself when you unplug and plug it back you might be connicting the wires back and then over time thay come back apart
The problem is in spark, or fuel. Rarely the Crank angle sensor. ECU could be going bad too.
the crank sensor "tells" the computer what piston is at the "power stroke" and what coil to fire also the next cylinder that is going to need fuel.
when my camshaft sensor was going bad, the vehicle refused to crank after being driven and parked for a few minutes. If you wait a little while it may crank. I heard of people pouring water on the sensor casing to crank them also.
The camshaft sensor is behind the water pump pulley and the crank sensor is mounted just above the crank pulley(dynamic balancer). If the crank sensor is bad . The car will simply DIE. If the cam sensor is bad it will simply not have sequential injector firing and driveability and MPG will be affected.BOBAnswerwhen the water pump pulley is removed you can see a sensor with 3 wires going to it at the top side of the crank shaft pulley. you might be able to see it with a flashlight and a mirror without removing anything. hope that's the right sensor.
Sounds like a timing belt. Crank sensor has nothing to do with the engine turning over.
there is no fire going to my fuel pump why is this I changed the main fuel pump relay
on the front of the motor under the front crank it has a plug going to the crank.
could be a bad crank sensor but that is very rare to go bad
i will presume that the engine will crank all the time, but not start all the time. check the power in and out of the distributor. if it has a system that uses a crank sensor then that would be the next in the line to check. hope it helps. duboff.
it sounds like the crank sensor is going bad try replacing it they are $16 at any part store
Looking at the engine on the right ride. Its going to be the round object where the timing cover stops on front of the engine.
under vechile near rear of engine going in from engine side toward transmission there is a 2 wire sensor with 1 bolt holding it in.
