    Default General Help, Still Startup Issues, Log File

    Still trying to sort out my my starting issues. It will crank and fire, stumble, then stall. Then restarting it will just crank n crank tell I hit the peddle. I have been told this puts the ecm into "flooded" mode and kills fuel. So with that I added 1gps to B4343 as speed demonded suggested a few weeks ago to me. I also removed fuel from my idle areas on the main ve table. I have no fuel added upon restart.

    I then logged startup, some idling, revving, a kill then restart(around 17:55). If you guys can, see what might be giving me fits here. If I need another pid, let me know as I'm going to log it on my way to work tomorrow.

    Some things I see wrong is my TPS is at .7v, when it should be .50-.55. Will work on that soon as I post this. My speed sensor is still not working. Could use some help on getting that fixed. My idle should have went down to 675rpms, but I never saw it get below 700. Rest I'm not really sure where it should be as I'm still a newb.

    I know when I put my new TB on...the TPS was at 0.4.
    The truck either ran like crap or wouldn't run.
    Now...I thought I'd need to wind the stop srew back to get it to 0 but it actually needed to wind forward. Once set to 0....no more problems.
    That's where I'd start.

    YOU ONLY NEED TWO TOOLS IN LIFE - WD-40 AND DUCT TAPE. IF IT DOESN'T
    MOVE AND SHOULD, USE THE WD-40. IF IT SHOULDN'T MOVE AND DOES, USE THE
    DUCT TAPE.
    IF YOU CAN'T FIX IT WITH A HAMMER, YOU'VE GOT AN ELECTRICAL PROBLEM.

    For some reason the scan tool didnt want to connect this morning.

    I think it was harder to start, and ran worse. But this was also after sitting all night and being colder.
