    Wont crank from ign switch

    Ok ok...before you all get too carried away. The car fired the fuel pump, injectors and ignition with an ecm for an automatic tranny. Mine is 5 spd manual. The ecm is looking for the neutral safety switch, which my car doesn’t have. It has a clutch switch. I’ve tried two other ecm. They did...

    Duramax stalled and no start

    Fixed! I pumped the button on the filter about 20 times, opened the bleed screw slowly and got bubbles then diesel. Pumped 20 more times. Turned the starter over and it started.

    Duramax stalled and no start

    I sprayed starting fluid into it and it started then died. Twice. Does this truck have a lift pump in tank or just the cp3?

    Duramax stalled and no start

    Yeah, cranked it with the bolt loose. No pressure. Then tightened and pumped up the fuel filter bulb. Then loosened bleed screw again. Got bubbles. But still no start

    Duramax stalled and no start

    Question. Shouldn’t the fuel line into the filter be pressurized? I loosened the banjo bolt and nothing. No pressure

    Duramax stalled and no start

    Ok. Yes. With how fast these batteries spin the engine, there should be some rpms. Ill go back and check that pump to see what was put in tank. Ill also check out the rag thing. Thanks guys. Ill post back when I get to it.

    Duramax stalled and no start

But it did after a couple tries. I drove about 20 ft and it stalled. It just cranked but no start...

    No crank no start

    Hey guys n gals. Sorry for the long absence. I changed the computer and ignition. I noticed the fuel pump primed, so I jumped the starter from the relay box. It started, and it ran. But won’t start from the ignition start switch. I get nothing. So I know everything is operating to run the car...

    No reverse

    2010 Pontiac g3 manual 5 spd. Transmission does not shift into reverse. When I put stick into reverse gear, it’s another forward gear. No reverse. Cannot find reverse in any other area of shifts. Just checking if there is something I can check or adjust before I change the tranny. Thank you...

    Carb full throttle at start

    Thanks guys. I found the leak. The bottom gasket had washers on each stud. I just removed the washers and bolted the carb back on and it ran perfect. But the engine is a performance engine. 4 bolt main, Aluminum intake, heads, roller rockers, all kinds of goodies....and it came with a carter afb...

    Carb full throttle at start

    Yeah...the large port in the back is not connected to anything. And the previous owner of this engine said this carb worked well for him. Guess ill find a line and run it to the power brake. Thank you.
