Hard Start
« on: March 27, 2016, 02:58:23 PM »

Greetings people who know a lot more than I do. I think I know the answer to my own question, but I will ask anyways. First off, I did a site search to no avail but... I had the fuel pump out of my 2005 SEEG to do a tank repair and repaint. I reconnected the fuel lines and re-clamped with worm gear clamps. Now when starting cold it spins over for a good 20-30 seconds before firing, warm is about 10 . Once running it has a slight "sneeze" and  stumble/miss through the throttle body. Last year, hot start was just a touch of the button. Am i tearing this thing apart again? Only saving grace is we still have snow on the ground. Thanks for your input.  :jalapeno:

There's a good chance the internal fuel line(s) have developed a leak.  It was a pretty common problem actually, and many of us changed the lines out along with the fuel filter during regular maintenance.  Both the intake line and outlet line are subject to rubbing on parts in the tank and developing leaks, as well as just failing from age.  The intake side will cause a problem anytime the fuel level is below the leak in the line, letting the pump suck air.  The pressure side would cause a problem all the time.  Low fuel pressure directly affects how much fuel is injected, so you would wind up with a very lean mixture that not only affects starting but overall running as well.  If your lines have never been changed since 2005, they are past due IMHO.

When you turn the ignition on, listen for the fuel pump and see how long it runs before it builds up pressure and shuts off.  If it runs more than a few seconds, or never shuts off at all, that would be a tipoff that you have a pressure problem.  It can be verified with a pressure gauge of course, but most folks don't have the setup to "T" a gauge into the fuel line.

Thanks Jerry for your words of wisdom. The fuel pump does indeed run for a couple of seconds and shuts off. It looks like I'm diving back in there to change the inlet line. Probably a good idea to change the filter while I'm at it.  Eventually I will learn, if it's not really broke, don't fix it.

Jerry, you were right on the money. Fuel line it was. Used a Napa submersible line, gold plated that it was, but cured the issue.
