    Crank no start no rpm 96 5.7

    Update. I can make the coil fire if I take the sensor out and take a screwdriver and pass it across the sensor the coil fires every time I do that. When I install the sensor it doesn't fire. Since the original sensor was damaged, how likely is the gear butchered bad enough not to work? I am...

    Crank no start no rpm 96 5.7

    Sorry to hijack the thread, but maybe we will all figure this out together. I replaced the crank sensor, and hooked up a scanner and am getting rpm, and spark, and it coughs a bit now. I am waiting for the snow to melt because it's outside and it snows in March and April and May sometimes June...

    Anyone ever change out a crank position sensor?

    My 96 yukon left me stranded on the side of the hwy. The cps looks like this. I have no spark, but have fuel pressure at the test port.

    GMT 400 Hydroboost swap

    I bought a 2004 Sierra 2500 to use the 6L as a ls swap into my Yukon. The hydro boost seems to have another part under the drivers seat bolted to the side rail. Looks like that may be the ABS unit. Anybody know for sure?

    Crank no start no rpm 96 5.7

    I am in the same boat with my Yukon. It died while on the freeway. Just like it shut off. I suspected the distributor because it is new Chineseium. I have 50 ish pounds of fuel pressure, new fuel pump. Replaced dist. no difference. New module, new coil. new plugs. No RPM on tach while...

    O2 sensor low voltage

    I don't know if I have room to reach the port and get the hose in the crack of the hood, then drive down the road at a hundred. I did just change the fuel pump with the finest Chinese delphi one, and it seems to be fine that way. Also, the tail pipe is pretty black.

    97 stumbles when cruising

    I had this almost exact thing happening to my Yukon. Do you still have the stock plastic distributor? I replaced mine with a Summit Racing one and the stumble at cruising is gone. The gear on the original one was sharp and pointy like a knife edge, not square like new. I went under the hood...

    O2 sensor low voltage

    When I flog the old girl around a hundred miles an hour, foot to the floor, I am getting two codes for O2 sensors under voltage. No codes ever if I drive normal.

    Flowmaster Cat outlet flange size

    I finally got that figured out. Cost me 50 bucks to have a flange cut with a water jet. Thanks for the help.

    Flowmaster Cat outlet flange size

    The pipe size is wrong, but the flange would probably work, just have to cut the flange off and open it up. the bolt dimensions should work fine. Thanks.

    Flowmaster Cat outlet flange size

    Hey everybody! I was hoping someone on here has some experience with the stock exhaust system on these trucks. My c1500 had a stock muffler that had a very large 3 inch flange on it that bolted up the the converter. I got a new Flowmaster cat that came with a huge flange, I am having a hard...
