I Am Still Having Problems With The Gsl-se. Orriginally I Thought It Was The Fuel Pump Wich I Just Replaced And Now It Is Doing The Same Thing.
Idles Fine (somewhat) Step On The Accellerator And It Dies Like It Is Choking Out. Some Times It Does Run Fine But You Rev It Up To 3000 And Hold Your Foot Steady And It Cuts Out Within 8-10 Second Of Running Fine. I Thought It May Be Out Of Gas So I Put A Couple Of Gallons In And It Ran Fine For A Few Minutes Then I Drove It Around The Block Shifting At 4000 Without Cutting Out And Half Way Home It Died Out Again. My Meter Says 1/8 Tank But I Dont Think It Works. I Know It Has At Least 5 Gallons In It. Could This Be Electrical Or Maybe Something To Do With The A/f Ratio Or What?

 

Try filling the tank... mine does the same thing and its the pickup tube. I think it has a hole or something in it. If my tank isn't completely full it will start chugging at about half tank. As soon as it started chugging I put about 7 gallons in and it was fine. Now I have to fill up every 2 days I did try changing out the fuel filter but did not help.

 

I would attach a fuel pressure gauge and follow the test procedures outlined in the factory or Haynes service manual. My focus would be to make sure/confirm the pump is supplying enough pressure and the fuel pressure regulator is functioning. If that checks out, that only really leaves a problem with the injectors if your issue is fuel starvation. Save pulling the injectors as your last resort, not the kind of work to do just to have a look.

 

When I Got The Car A Few Months Ago There Was No Acceleration It Took A Minute Just To Get Up To 45. So I Pulled The Injectors Wich Were Very Dirty And Cleaned Them. I Also Replaced The O Rings And Intake Gasket, Set Timing And T.p.s. This Was Fine For A While Til 1 Day I Went Up A Hill And This Was Happening. Also When It Does It If I Turn The Car Off And On Again It Is Fine For A Little Bit. I Dont Know. It Has A New Fuel Pump Clean Gas And New Fuel Filter.

 

Oh And My Fuel Level Sender Dosnt Work It Stayes At About 1/8 Tank And I Have About 5 Gallons In It

It sounds like its starving for fuel. Try pulling one of the vaccuum lines near the front of the intake and spray some throttle barrel cleaner down it for a few seconds, go back and turn the car over and see if it runs up more than it normally does. If it does, something may be wrong with either the injectors or the fuel rail assembly.

EDIT - make sure you reattach the vaccuum line before you start it

FWIW... you are experiencing the exact same symptoms mine has when I run the tank below half and the pickup line starts pulling in air bubbles through its hole / crack and not enough gas. It's a real easy thing to check if the fuel pickup line is hosed by just filling the tank with 5 more gallons or filling it full.

 

I pulled your original thread regarding your problem, appears you have replaced almost every fuel delivery related part, maybe start looking back at the ignition. I noticed you went through the wires and plugs but was thinking of the ignitors. Some say they either work or they don't, not exactly. I have had the leading ignitor on my GSL give me hell by going in and out once the car got up to full operating temp., causing a severe loss in power. Lost a few on my SE and GSL in the trailing position, killing the car at random but was able to start it back up and continue driving, eventually going completely out and disabling the car. Didn't see you mentioning this so just use the ignitors off the GS on the SE.

Just caught the video after posting, going to watch it a few more times. Sounds like fuel starvation or a bad leading ignitor.

 

Ah I didn't even think about that... I've seen other threads of folks complaining about similiar symptoms when it turned out to be igniter related. Definitely worth investigating.

 

Ive Tried Switching Them Also And It Dosnt Seem To Be Any Different. I Thought Maybe The Trailing Was Bad, Switched It, Then The Leading. Same Thing. Fuel Rail Is Fine With A New Pulsation Damper Should I Be Able To Feel It Pulsing?

 

Are you able to get it to turn over at all? If everything with the ignition is fine you should be able to pump some starting fluid into the vaccuum lines / intake and get it to at least turn over a few times. If that isn't happening... something besides fuel is wrong.

 

Hey,
I am just starting a restoration on an 84 SE. My first task was removing the tank, filter and pump to replace them. FYI, the fuel line that connects to the fuel pump itself, (the feed line from the tank) has a little cone shaped filter inside the line. It is a fine mesh screen shaped like a long pointy cone. When I took mine out, there was so much rusty sediment collected in it, there was no way fuel could have ever easily passed through the system.

It would not take you too long to check yours. I have not seen this mentioned yet on the board, but I am very new here. I'm just glad I saw this and cleaned it out before going through a bunch of other more difficult fuel starvation tests. Best of luck.

 

YEP I WAS SURE TO CLEAN THAT OUT VERY WELL WHEN I REPLACED THE PUMP.
