    1987 Buick Grand National 35k miles

    Don't get me wrong, the GN is very cool and I still do like getting the head turns, thumbs up, "Hey nice car", horn blows, waves and questions about my GN, and it is fast but when I want to go faster, stop faster and turn better the Mustang feeds the need. The GN gets more attention from those...

    1987 Buick Grand National 35k miles

    Man, I bet that's quite a car. My 12k mile Mustang puts just over 700 hp to the wheels. The GN will just be for nice day family cruises here and there until it's sold.

    1987 Buick Grand National 35k miles

    Well, I bought this car to turn it into an 11 second street/strip car but after much thought I didn't think such a low mileage car is such good shape should be modified so heavily. I probably should've bought a higher mileage GN that already had some modifications. It is about 95% original...

    Fuel pump prime

    Earl, I checked the signal from the ECM using a test light at the dark green/white strip wire, turned the key forward and got the light for 3 seconds. Then I jumped the relay connector, turned the key and got the pump running. I'm far from an electronic expert but with the signal coming...

    Fuel pump prime

    To me everything was showing relay problem. I took a chance and went and got another new one, plugged it in and now the pump is priming. Thanks for all the help.

    Fuel pump prime

    OK, first I had my wife turn the key two clicks, I felt the relay click and then click again after 3 seconds, then I jumped the connector, turned the key forward and the pump ran. Then, I stuck a test light in the connector at the dark green wire coming from the ECU and the light came on for...

    Fuel pump prime

    We did a brand new fuel filter when we put the Walboro in it. That's what so weird to me, when I bought it the pump had no prime but ran fine after starting, the seller said the pump was bad and gave me the walboro with it. I put the walboro in it along with a new fuel filter and bam, it would...

    Hmmm, I never thought of that but I could feel the FP relay click with my fingers while my son turned the key.

    Fuel pump prime

    I tried a new relay this morning and the same thing happened, I could hear it click once and then click again in about 2-3 seconds but the car just cranked for about 10 seconds when I tried to start it. I turned the key off and then back forward again and it fired up after about 5 more seconds...

    What are these connectors for?

    I was reading up on how to test the fuel pump by jumping a wire from the positive terminal on the back of the alternator with a black connector behind the A/C pump and I think I found the black connector. But there was also a green connector that has some black paint on it real close to the...

    Fuel pump prime

    It runs and I do drive it but I still want it to work properly. It should start right up and not crank for 10 seconds before starting.

    Fuel pump prime

    No fuel pressure gauge. When the key is turned forward two clicks I can hear the relay click on and then off after 3 seconds or so but I cannot hear (or feel the pump with my hand on the tank). The car just cranks until the oil pressure builds enough pressure for the pump to kick on and then it...
