more help needed. I disconnected the fuel line from the front of the pump going to the fuel filter reservoir and disconnected the leads going to the pump. I hooked the pump to the battery and hear it turning however I am not getting fuel from the tank. I ran it for about 45 seconds. should i have run it longer? is there a filter inside the tank and can that be plugged? can the pump be vapor locked if or is the pump bad? I picked up a volt meter today I still don't know if there is power going to the pump. What should the meter read when I turn the key on to the pump I just bought the meter today.
Fuel should be coming out of the pump sooner than that... So, it sounds like either the pump isn't "pumping" because it's bad OR it's either sucking air in the tank or the supply line because the level in the tank is too low, the screens are plugged, or the line is broken somewhere.
Sounds like it might be time to pull the pump for further testing. You could run it with the suction side in fuel to see how it pumps maybe,,,, If you had a vacuum source you could also see if you can draw from the supply line.
Is the tank up over 1/2 full? Could the gauge be bad and giving a false reading?
You should find battery voltage at the pump when you first roll-on the key (at least for a few seconds) The PCM provides a path to ground to energize the relays coil and close the contacts of the relay to supply power to that pump.
The other thing to consider is,,, if it's the original pump and 10yrs old, you're doing all this outside in the cold, maybe just throw-in a new one and see if it pumps (what are you really losing even if it Isn't the pump? How much longer would it have gone...
