1998 Audi A4 1.8T fuel pump does not turn on

I need help troubleshooting and locatingthe crankshaft sensor. I know that the fuel pump will not turn on if the ECM does not sense the crank rotation. I have tested the fuel pump relay and supporting connections. If i jump the relay i get 60 psi to the fuel rail. I have an open signal from the ECM with the LED test light.
I need to know where the crank sensor is and looks like and how to test it in the auto trans.

If you have diagnostic equipment you will be able to see the signal through serial data(if you believe it)the cranksensor is located near the rear of the engine pointing towards the radiator i think it goes to a grey plug....

Audi A6 2001 does nothing when I turn key. But all electrical is working.


Well something has to be wrong since the car "does nothing."

Battery good? Starter? Fuel pump? Ignition coil? crankshaft sensor? Compression?

I have a 1998 Jeep cherokee sport. Was driving today and it died. Now there is no spark and no power to fuel pump. Changed fuel pump today and it won't run. Recently replaced oxygen sensors too


U need to check the crankshaft position sensor. The fuel pump will only have power for 2 seconds I till it sees a crank signal. It' controls the asd relay which turns on your spark and fuel

I need located the Fuel pump relay I just installed new fuel pump but the car is not having the right fuel pressure its 1998 Audi A4


The relay just turns it on and off - if the pump comes on the relay is fine. You may have a bad fuel pressure regulator. If you want to change or troubleshoot the relay you need to remove the lower dash panel below the steering column. The relay is marked with "372".

Starter went out replaced it, then truck would turn over but upon releasing the key it just dies as if no fuel. Has fuel, pump coming on, has spark, I have replaced the intake( which is made of plasti),...


Check the Camshaft Position Sensor or the Crankshaft Position Sensor. Those are the modern day Distributor Caps of the 21st Century, if neither of them are working the ECM (Computer) does not know what position the Crankshaft is in so it will not be able to start your motor.,

My 1998 Buick Regal GS will not start. The battery is only one year old and the starter is turning. The wiring for the spark plugs was replaced 2 years ago. Is this a fuel pump problem? If so I would like...


If the motor is turning over, then the battery is good. You are either not getting spark or fuel.
If not spark, the crankshaft position sensor is usually faulty.
If no fuel, either fuel pump or fuel pump relay is bad, or clogged fuel filter, or fuel pressure regulator is faulty. You have a fuel rail that has your injectors attached to it. It should have a test port on it that looks like a tire valve. You can put a rag on top of it,, press it in and there should be lots of fuel pressure, If not, either filter is clogged or pump is not running either due to bad fuse or relay or pump is bad.
For spark, there is a crankshaft position sensor that screws in engine block next to the crank. Then from here the wires go to ignition module and coil packs, then to plugs and wires. You can test any relay or sensor with an ohmmeter in the ohm position. You can test any power in an electrical unit with a voltmeter

My engine turns over but won't start


If it will turn over but not start, it could be a fuel delivery problem ( fuel pump), clogged fuel filter, bad spark plug or wire, or it could even be something like a crankshaft position sensor. Try the cheaper fixes first. Hope this helps. Good luck

Crank sensor location


Look around the bottom of cylinder block. Or near where the flywheel is to, because the crank angle sensor works from missing teeth or magnets on the flywheel or a cog/wheel fixed to the crankshaft.Hope this helps
