what sensor controls the fuel relay
It is under the driver's seat.
Check the fuel pump fuse & relay.
If you're looking for the fuel pump relay on that 94 S10 with the 4.3 L engine, it would be found on the convenience center located to the left of the steering column at the lower edge of the dash. I don't know of any "fuel relay sensor".
there is no fire going to my fuel pump why is this I changed the main fuel pump relay
if you mean the fuel cut off switch, its in the trunk.
No-it has nothing to do with it- Yes, if the computer is not getting a signal from the crank sensor it will not activated the fuel pump. How you figure this-Please explain-The crankshaft position sensor jobs is to identify the position of the piston so that it will tell the computer to fire the coil/s. The Camshaft sensor synchronizes the fuel injector. The fuel pump relay/circuit opening relay and oil pressure/inertia switch are used to control the fuel pump- On a Chrysler vehicle there is no oil pressure or inertia switch. If the PCM does not have a valid crank sensor reading it shuts down the ASD relay, which powers the entire fuel system. I Didn't know, I was dealing with a Chrysler product here or a Dodge/Plymouth-Yes I'm aware of what the Auto Shutdown Relay does with the ignition coils/fuel injectors on these vehicles-On some of these vehicles the ASD relay powers the fuel pump relay to activate the fuel pump as far as I know-Anyway I'm not a Chrysler expert thanks for sharing the knowledge of the CPS
The crankshaft position sensor has nothing to do with the fuel pump but a defective fuel pump relay and fuel pump fuse will and also a missing ground circuit will cause it not to run
testfor badcam or crank sensor. scan car for codes
Your relay sensor is likely faulty
no fuel sensor on the 91 liac only a fuel pump relay and the filter and the fuel pump is in the tank and the filter is on right side under the car below back door and the fuel pump relay is in your fuses boxs in side the car not under the hood.#3 up from bottom right side of fuses boxs.
Fuel Pump is located inside the fuel tank. Both the sensor and pump are combined.
