    Crank-No Start 99 Tahoe 4x4 5.7

    Passlock will usually let it start and run for a second before it kills the injectors. Your video doesn’t really fit that.

    98 Tahoe locks problem

    I’ve read where some had a bad door lock relay cause that as well. The relay and the remote control module are somewhere under the dash…

    1998 Yukon low operating temperature

    Here is the diagnostic from the 98 manual. Do you have any exhaust leaks on the passenger exhaust? If you have a scanner, graph the up and downstream O2 sensor voltages together. The upstream will oscillate (lean to rich) while the downstream should be relatively stable. If it mimics the...

    taillight issues

    I’d start with the reverse since it’s simpler and odds are that if you fix it you’ll fix the others. Look for connector C409 (two possible locations below) and check for voltage at the light green wire’s pin when in reverse. The engine doesn’t have to be started for the reverse lights to...

    Bolt In Roller Pins -- Cunningham Machine

    Finally got around to doing mine as well. It took longer to get the old one out than to put the new one in. Should’ve done the door pins as well (they’re original) but couldn’t get motivated.

    4l60e PWM delete

    Thanks for chiming in guys. I’m going to drive it for a bit more and see what I think - will probably swing back by the shop and have them ride along.

    4l60e PWM delete

    Thanks, I think I was expecting the soft engagement like a gear shift rather than the firmer action.

    4l60e PWM delete

    Thanks, Nick, I appreciate the input. I think it’s definitely a case of me just being used to it driving a certain way and not being familiar with the alternative setup. So during lockup under heavier throttle, it’s normal for it to have two quick skips or “bump-bump” to it? It’s hard to...

    4l60e PWM delete

    I had the transmission rebuilt on a 1998 Chevrolet K1500 (broken sun shell) and they deleted the PWM and installed a reman torque converter (1611-1654 stall). I don’t know what they used for the delete. At TCC lockup, how are these PWM deletes supposed to feel compared to the stock...

    98 Yukon, The engine restore starts.

    If you’re having a shop do the install, pay attention to the warranty labor rate if it has to be yanked out and shipped back. Some remans will only reimburse a percentage (say $50-$70/hr) for labor on warranty claims. It surely varies across the country, but most shops are probably in the...

    96 tahoe electrical issues

    If it has a trailer harness, see how that looks. We had a 98 with some questionable “homemade” connections that caused blown fuses, loss of brake lights, interior lights and either the headlights or the running lights (I forget which).

    4 Wheel Drive Issue

    Was the idler arm bracket also replaced? Despite the new parts (or in case you got a bad one) it’d be worthwhile to jack it up and check for play in the steering linkage.

    A/C pump on and off

    Try post #111 in that link. It looks like another member posted another 1999 copy onto a Google drive.

    Here’s the diagram from 1999. The full manuals can be downloaded at the link below (see post #77): https://www.gmt400.com/threads/88-98-service-manuals.43575/page-8#post-1234512
