    Sulfur smell when letting off the gas

    Thanks for the advice. While it drives well, it does have the feeling of retarded timing....even though it’s set to 0. Over this long weekend, I’ll mess with timing and see what results. You’re a Buffington, too? So cool!

    Sulfur smell when letting off the gas

    Hi Gang! Just had true-dual exhaust added to my 1990 burb, with high-flow cats and flow master mufflers. Truck runs amazing. However, when I let off the gas, I get a sulfur smell in the truck if I have the back window down. I know, simple solution to this is to drive with the window up! But I’d...

    TBI fuel pump unresponsive

    Another follow up: I wired 12v directly to the fuel pump at the rear of the truck...no whir, no response at all. Looks its been a shot fuel pump the entire time.

    TBI fuel pump unresponsive

    Next update: green wire at relay 12v when switched on, so that checks. rechecked power at back to pump; pink wire is 8.5v, white/grey is 12v for about three seconds, then off.... so...i think I was not probing the connectors by the pump correctly before, as I had my wife cycle the truck on...

    TBI fuel pump unresponsive

    Update: 12v on orange wire, check! Ground solid: check! Green wire....zero. Should it only read 12v at initial key on/cranking? I was alone and could get to the engine bay fast enough to tell.... checked wiring to oil pressure switch and all looks good; nothing corroded/broken/disconnected...

    TBI fuel pump unresponsive

    Thanks buddy; I’ll get into this today and let you know what I find. Has to be some little break or something, as it happened all of a sudden. Oh, and you know what? When I first got under the hood to check out why the truck wouldn’t start, I noticed the fuel pump relay ‘dangling’ and not in its...

    TBI fuel pump unresponsive

    Update! I found the fuel pump ground disconnected. Reattached to frame rail, and still nothing. Measured 6.25 v on power line to fuel pump (measured at connector near fuel tank). Replayed fuel pump relay, no difference. It’s raining and dark out now, but tomorrow, I plan to attack this again...

    TBI fuel pump unresponsive

    Hello! Okay, found the fuel pump ground disconnected!!! However, for the life of me, I cannot figure out where it was connected....and I'd rather not drill another hole in the frame. There must be a logical place for this to go. Any ideas?

    TBI fuel pump unresponsive

    Hi gang, Been chasing down a crank-no-fire situation on my 1990 burb (350 stock TBI). After running around 50 miles or so around town one day (running perfectly, as far as I can tell), she would not start when I came out of the supermarket...just cranks away, but no firing! I can get the...

    Secondary battery and isolator install complete!

    Great to catch up on this thread. My secondary battery and isolator are working as planned. Just added a gang buss 8 distribution box and controller on the inside of the truck. I even found a new ‘portal’ through the firewall that I never saw reported anywhere on the internets! Just below the...

    brake pedal rattle

    Hi folks! My brake pedal rattles back and forth in the cab when I'm not pressing on it. Seems like a bushing is eroded/gone, but I can't for the life of me find anything about this. Does anyone have suggestions on what I can look for, or what the cure for the problem is? Thanks in advance!

    TBI pods are leaking!

    thanks everyone for the comments. Your support really lifts my spirits! I tried ATF to lube the o-rings prior to install. That seemed to be the go-to solution. I think perhaps the petroleum jelly is next up to try. And something else: when I first reinstalled new o-rings, the truck ran...

    TBI pods are leaking!

    Got more o-rings on their way, arriving Mon. i think I'll order a set of injectors, too, that I can return if it turns out mine are okay.
