Caboobaroo Posted January 11, 2009 Share Posted January 11, 2009 Maybe rust in your tank, tap the fuel filter on the ground and look for rust. Those "jumper wires" are the fuses, they are called fusible links. I'd crimp off the line that goes from the fuel tank to the pump under the car with some vise grips, remove the line from the pump and release the vise grips. Drain it into a coffee can with some sort of paint strainer on it and look for rust or anything else that could be getting clogged in the lines or the tank. If yo do find something, either replace the tank from any fuel injected EA82 car (2wd, 4wd, manual, auto, it doesn't matter) or have it professionally cleaned out.

areez Posted January 11, 2009 Author Share Posted January 11, 2009 I will check the tank too. But today i found the real problem. The connection on the fuelpump is loose. And i have to hold it tight together to get the pump going. Tomorrow i'm doing a new connection and hopes for better function. Was no rust in the fuelfilter when i checked it today. Hopefully i can drive the car tomorrow My Grandpa will be really happy now. He bought this car from the Factory 1987 and sold it to my cousins who drove rally with it Or they thought they where It went from mint condition to crappy in 2 years But i think i can get it back up again.

Thanks for the update. The pump you have sounds like a pump for fuel injection? I did not look it up to see. I mean to say, it's not the volume so much as it is the pressure it delivers the fuel at. The factory pump when operating properly is very well suited for the engine in stock form. Link to comment Share on other sites More sharing options...
areez Posted January 14, 2009 Author Share Posted January 14, 2009 So you dont think i should use the Walbro pump instead ? Because here in sweden its almost impossible to find a used pump to this car. And a new one costs 3 times more than a Walbro. The thing with my pump is when its out in the cold its just working when i hit it. But inside it works all the time. And its not the connections that is the problems because i have changed them now.

Sir, if it is indeed meant for fuel injection systems yes use it (see below) Your old pump may have had a fuel damper connected directly in line with it. Some people leave it some don't. The thing with my pump is when its out in the cold its justworking when i hit it. But inside it works all the time. And its not the connections that is the problems because i have changed them now. Well this is an entirely different situation. My previous statement was based on the fact that you said "But today i found the real problem. The connection on the fuelpump is loose. And i have to hold it tight together to get the pump going." Link to comment Share on other sites More sharing options...
