Hi, I have an 81 DL240 and it recently just decided to quit running. Here's the symptoms: It randomly will start or won't. However, I've found if it won't start, I can loosen the gas cap, tighten it back, then it will start. It will run fine for about 2 minutes and then it will start cutting out. If I try repeating the process just mentioned it does do any good.
Any suggestions?
Thanks,

Sounds like a fuel tank venting problem. See if it will run for longer that 2 minutes with the cap off.
Make sure the fuel pump relay is working correctly. Listen at the fuel filler when someone is cranking to hear if there is any fuel splashing when the tank is below half full. This indicates that there is a leak in the fuel feed line from the prepump to the main pump. Make sure the main fuel pump runs whenever you are cranking the motor. Usually your symptoms are those of a failing main pump.
