Fuel Pump Running all the time and Starter Issues

[CutlassSL91]

I have been having two major problems lately:

 

1. sometimes even after my car is completely shut off, my fuel pump continues to run, and last night it completely drained my battery.

 

2. yesterday and today, when i started my car, it made a horrible buzzing noise instead of cranking. After a few tries the car finally started.

 

ANY IDEAS APPRECIATED!

Stuck relay? Wire short?

 

Have you done anything to the car recently?

 

Killer bees stuck in the engine?

When the fuel pump continues to run, try unplugging the oil pressure sensor. If that stops it, replace the sensor. If that doesn't help, try removing the fuel pump relay.

 

I have no ideas on your 2nd problem. Could be a poor connection between battery and starter, or something wrong with the starter solenoid.

ok, it wouldn't start today, and the digital dash was doing some weird stuff. I think it is the fuel pump that keeps running. So the oil pressure sensor or the relay would be the problem?

I have the same problem and replacing the relay did not help. I am 99% sure it's my oil pressure sensor/sending unit.

 

I'd replace your relay just in case it's that, but mostly like its the oil pressure unit.

Our Caravan does that occasionally, or at least it has been lately. It'll just buzz and not try to turn the flywheel. If I let off and try again it usually starts fine the second time around. I seem to remember it doing that about a year ago.. I think the starter got replaced and it stopped doing it til a few weeks ago. Don't know what actually causes it though.. kinda weird.

got a new fuel pump relay and it did not solve the problem, so an oil pressure sensor you think?

[CutlassSL91]

i need a part number please....

[gp90se]

before throwing parts and $ at it, unplug the OPS first and see if the issues go away.

[CutlassSL91]

will the car run normally without the oil pressure sensor? Also, is the oil pressure sending unit the same thing as what gives the reading on the guage?

[gp90se]

the sensor is for the light/gauge/fuel pump/ecu reading.

 

some cars beep without oil pressue, dont remember if w-bodys do or not.

[CutlassSL91]

so removing the sender will cause the fuel pump not to run, right? So how much is a new sender? and what is the part number?

Don't remove the sender, unplug the harness from it. That will 'disconnect' it's signal, shutting down power to the fuel pump if it is in fact sticking.

 

Not sure on part number or price.

 

Try jacking the car up and either have a friend start it or get a remote starter switch. See if you can get it to buzz again, and if you do, see what isn't happening.
