Hello everyone. This is my first 914 world post and ask for help.
I am trying to get fuel into the L jetronic system on this 1975 1.8. I have power to the fuel pump- put in a new fuel injected type fuel pump, new fuel filter. When I put power on I can hear the pump gasping. It is loud and sounds like it is not getting enough fuel, however the fuel from the tank flows in just fine (I've checked- and rechecked). So I think it is not building pressure in the system. So I've followed the lines around the engine to what I think is the pressure regulator. In the manual I have the pressure regulator has an adjustment on it. The one in this car doesn't. I can't find anywhere where there might be an adjustment. Please someone guide me. The car appears to have new fuel lines and I'm told it ran once before until the fuel pump quit. It should have been plug and play. A few more facts: Its got fresh gas. I don't think it has run in about 8 years. Stored inside- I was told. Clean car really. The owner died and his widow has asked for a hand. I put a fresh battery in to. Thanks in advance.

(IMG:style_emoticons/default/beerchug.gif) Glad to hear it, and a pleasure to assist you thru this. I imagine that your fuel pump noise went away, since the engine lawn mower noise drowns it out?
Your high idle may be due to several vacuum leaks. I would get this fixed right away, as it may cause a back fire and ruin your functional AFM. Thanks Mike and Ed, for your kind words earlier in this thread. I'm always ecstatic saving a Ljet from a possible carb retrofit.

QUOTE(timothy_nd28 @ Oct 23 2012, 10:23 PM)  I'm not so lucky. I followed all the directions inn this post and have everything wired correctly. I have done the Air Flow Sensor test and it checked out fine on resistance and voltage change. Fuel pump was wired to run continuously withg ignition "on", I think through the ignition switch which I know is bad, but I didn't wire it. Now that everything is wired right, the pump runs with the ignition in the off position! My realy has two numbers on it FI Side says 0332 514 129 and Ignition side (which I think is bad) says 071 906 059. Should I just order the 0332 514 120 relay that is discussed in the thread, if it's still available? Or are there additional tests I can conduct to really be sure that my ignition side of the relay is bad. Any help will be greatly appreciated. |
