eVIL_NTT Posted September 28, 2010 Share Posted September 28, 2010 I was coming back from a gorcery run and the car (EA81 '82 GL wagon) died on me much like running out of gas with less sputter. I tried to restart it a few times, but it would stay running only a few seconds then die. I had a friend listen while I tried to start it and he said he couldn't hear any fuel pump sounds. Is there another way to check if it is operational? Any advice or things to look for when installing the new pump? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 28, 2010 Share Posted September 28, 2010 (edited) Check all your fuses to start with. Actually put your hand on the pump while someone cranks the engine over. It should be pretty obvious if it's running or not. First thing is to check for voltage at the pump connector while cranking. If that's good and the pump doesn't run then you have found an issue. If you have no voltage then start checking the fuel pump control unit located above the hood release handle bracket at your left knee. It needs ignition switched voltage, tach signal, ground, and then feeds power to the pump and some of them also run the choke.

GeneralDisorder Posted September 28, 2010 Share Posted September 28, 2010 No problem - get back to us on what you find. EA81's are very simple so this shouldn't be hard to figure out. GD Quote Link to comment Share on other sites More sharing options...
eVIL_NTT Posted September 28, 2010 Author Share Posted September 28, 2010 The basic fuel pump stuff, nice to know where the control unit is though. I love working on the car actually, it has taught me most of what I know about vehicle repair. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 28, 2010 Share Posted September 28, 2010 One of the last great "learner's" cars IMO. In many ways it's actually simpler than my '69 GMC Truck. Frankly I consider myself very lucky to have owned an EA81 as one of my first cars (that wasn't borrowed from the parents). I learned a lot out of neccesity and though I wasn't as accutely aware of it at the time as I am now - the EA81 saved me a lot of headache's through being a very simple and forgiving machine.

eVIL_NTT Posted September 30, 2010 Author Share Posted September 30, 2010 After a bit of inspection of the fuel pump and some "magic" (read: wiggled connecters) it started right up. I cleaned the connecters and I hope that will be the end of any fuel problems. I am wondering though, if the control unit is going out, will I have an on-again off-again fuel issue as it continues to fail? Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 30, 2010 Share Posted September 30, 2010 I have never seen a FPCU fail. I doubt that's your issue. Sounds like the corrosion was the culprit. GD Quote Link to comment Share on other sites More sharing options...
eVIL_NTT Posted September 30, 2010 Author Share Posted September 30, 2010 That's what I was hoping to hear. Thanks again! Quote Link to comment Share on other sites More sharing options...
