Runs for a Second and Dies, 1.8fi Starts, Runs for a Second, then Dies. Options

Any advice on a forum article I should go to, or advice on how to troubleshoot this would be appreciated.

I have replaced the fuel filter and fuel pump, as I originally thought it was a fuel issue. Now I am not sure.

Thank you!

I gather you are looking to be directed to a troubleshooting thread? The search function on 914World is not the most efficient. Best to use Google. Type in "914World" and then your question/search terms. That will usually get you where you need to be on this site.

If you are looking for direct advice, there are so many questions.....Give more information if you want help.

1) What made you think it was a fuel problem? Did you check fuel pressure/flow first? Just replacing the fuel pump and filter is not a guaranteed fix for a fuel problem. There are many other components to the system. Given that it runs for a second and then shuts off it could be that the double relay is initially firing the fuel pump but then the fuel pump is not being given power after the ignition is turned to the run position. Check your repair manual for how to test the system. Very briefly, push open the air flap at the AFM and see if the fuel pump starts to run. That's only one quick example of part of the diagnostic procedure for the fuel system on an L-Jet car.

2) What's the background on the car? Was it a good running driver before this happened? Has it sat for years?

3) Did you do any work on the car and now it won't start?

4) What have to do so far to diagnose the problem?

You'll get lots of advice here. People are very willing to help and the hive mind has a lot of collective knowledge. Can't argue with starting with a smoke test as the L-Jet system relies on vacuum.

Good luck!!! I'm sure you'll get this fixed.

Thank you, I have a lot of testing in front of me. I just did not know where to start. I thought since it starts and dies, I went immediately to fuel in my mind, that may have been shortsighted. I figured I would knock out some of the easier things that I thought I would be replacing anyway not knowing age or true condition. And then rather than reinventing the wheel, ask the jockeys that have been here before me and better at it.
