Demolition Posted March 23, 2012 Share Posted March 23, 2012 I finally have some time to work on my rig today. The number one thing to do is check my fuel pump. I got the three bolts off and disconnected it all. Now how exactly do I inspect the Pump to see if its ok or not?? Mine is a little caked in mud... Thanks In Advance Quote Link to comment Share on other sites More sharing options...
desertsubaru Posted March 23, 2012 Share Posted March 23, 2012 Did the car run before you took the pump off? Quote Link to comment Share on other sites More sharing options...
Demolition Posted March 23, 2012 Author Share Posted March 23, 2012 No it did not. I would try and start it but it wouldn't start, I thought it was my timing belts but it was not, Thats why im thinking fuel pump.. Quote Link to comment Share on other sites More sharing options...
Subruise Posted March 23, 2012 Share Posted March 23, 2012 im assuming you did not hear the pump prime when you turn the key to the ''on'' position? is the coil plugged in? spark plug wires in correctly? usually th fp gates noisy waaaay before it stops functioning.

man on the moon Posted March 23, 2012 Share Posted March 23, 2012 The easiest way to tell is to pull the air boot off the intake and see if the injector is squirting gas. It looks like a hose, there is no mistaking if the injector is firing. If you are alone, roll up a piece of newspaper and stick it down into the throttle body. Crank for a few seconds, and check to see if the paper is wet/smells like gas. And keep in mind that even if it ISN'T firing, that doesn't mean the pump is bad (though it may be). A bad coolant temp sensor (the one at the thermostat, not the radiator one), a broken timing belt (which you said it wasn't), and a bad crank angle sensor (in the distributor) will all keep the injector from firing and/or the pump from turning on. If you can see or pull the ECU from where it sits under the steering column, set the key to 'on' and note the code/codes it blinks at you, if any. Six short codes is all clear. If you unplug the battery for a few seconds it will clear the codes, then try to start the car again and see what pops up. Quote Link to comment Share on other sites More sharing options...
987687 Posted March 24, 2012 Share Posted March 24, 2012 Just pull the supply hose (the one that goes through the fuel filter under the hood) and stick it in a bottle. It should squirt out a little bit of fuel when you put the key in RUN. And it should also run continuously when the engine cranks. Next thing I'd check is if you're getting power at the pump.
