74 1.8 with L-Jet. Starts and runs perfect for a while.
After driving or running for anywhere between 5-20 minutes, the engine loses all power, but still sounds like it is running for about 20 seconds, then dies completely. While it still sounds like it is running, I can put the pedal to the floor and it makes no difference. If I try to start it right away, it will not start. Every time so far, after I wait a couple of minutes it will restart and run like nothing happened for a few more minutes, then die again. I have replaced the dual relay with a known good. I think the next suspect is the fuel pump. I see a T fitting in the driver side fuel rail that is plugged by a bolt. Is that where I would connect a fuel pressure test gauge? Is that the best next step to check? |

You can also hook up a test light to the fuel pump circuit to see if the pump is getting power or not. If I am remembering the L-jet system correctly, with the key on but engine off, pushing the flap open in the AFM should make the fuel pump run. You can check for power and pressure in a single test.

excellent advice, the only other thing is if the flap is sticking it would die then the flap would unstick and one could just drive off, especially if it sort of runs like it is running out of gas, it would be sort of flooding out
