    Hard start 96 Suburban

    I cycle the key several times before trying to start (after it has set over night) and it will fire for a second and that's all, cycle some more, another quick fire, it does this for at least 6 tries. Once started it runs great. It has set for quite awhile and the problem has just gotten worse...

    Hard start 96 Suburban

    No codes, I haven't been able to test anything yet. It runs strong after it starts, so I'm ruling out the filter

    Hard start 96 Suburban

    5.7 acts fuel starved, really hard to start cold. After it's been running, it fires right up. Any ideas?

    4 wheel drive problem

    Talked to a local shop about scanning it and he said they never use aftermarket switches. Dealer wants $135 for one, holy cow, if it works I guess it's worth it

    4 wheel drive problem

    The guy at NAPA called the company tech line and they said the module can send too much voltage to the switch and burn it out, both new switches only lasted a week or so and I only used the switches long enough to see if they worked. I guess I need to call NAPA again. I'll try holding a button...

    4 wheel drive problem

    I appreciate the help, I'm a former mechanic with health issues and can't get around like I used to. I'll try to check the ground first, then check the voltage at the switch. Thanks

    4 wheel drive problem

    The new switch lasted two weeks, put in another new one, it lasted two weeks. Napa called the companies tech line and they said the control module is probably feeding back to the switch and burning it out? Anybody ever hear of such a thing?

    4 wheel drive problem

    The motor was replaced a couple years ago, I might take chance and get a new switch. I don't know which TC it is. I'd rather be driving my 96 Suburban

    4 wheel drive problem

    05 yukon does not go into 4wheel drive, lights on the switch are all usually off, yesterday on the hyway, the 4low light came on, a scanner shows the computer is getting a signal from the switch, but that's all it says, any ideas?
