    7.4 EGR bypassed

    I dont have to worry about issues with an inspection, not required where I live. The new tubes on ebay are aftermarket, none have name brands except for one made by Dorman. The Dorman one is about $80. I figure the used factory tubes are high since this is a discontinued factory part. I'll...

    7.4 EGR bypassed

    I just bought a 97 c2500 Suburban with 7.4l. PO removed upper intake to replace fuel regulator and twisted the EGR tube closed while trying to disconnect it. He's been running the truck that way for a couple of years. He just unplugged the pigtail on the EGR valve. Truck seems to be running...

    Good ol' Random Multiple Misfire

    Had this happen to me on my 2000 C2500 7.4 a couple of months ago. Coming back from a car show, pulling a loaded trailer, it started missing, occasionally backfiring and loss of power. I was about 125 miles from home and decided to try and nurse it on in. When I got home, could smell the gas...

    1998 K1500 5.7 starts then immediately dies

    Ok, it was the passlock acting up. Did a reset and it fired up after the first cycle. I have a parasitic battery drain issue (which led to the whole no-start problem to begin with) that I'll try and solve first, then see about replacing the resistor and hopefully that'll keep me running long...

    1998 K1500 5.7 starts then immediately dies

    Yes, got the message and not arguing it. Just trying to get a better understanding of how it all works; resistor bypass, PCM reprogramming, etc. The good thing is, the suburban is not my daily driver, use it to pull boats and my hunting vehicle in the fall. And, luckily, it died in my driveway...

    1998 K1500 5.7 starts then immediately dies

    What has me a little stumped is the bypass I did 10 years or so ago on my C2500 is still working. I bought a "kit" on ebay which was basically instructions and a resistor. The resistor, according to the info that came with it was tested to be 2,750 ohms, wattage not stated. The resistor I put in...

    Has anyone had experience with the bypass module that Newrockies offers? Supposed to completely bypass the system without having to do the PCM reprogramming.

    1998 K1500 5.7 starts then immediately dies

    OK, thanks for the info! I'm going to replace the current resistor with another one this weekend just to make sure that's my problem and then go from there. Will update progress when I do. I did this same bypass on my 2000 C2500 7.4 about 10-12 years ago and have never had an issue. May be the...

    Yes, I did mean resistor. I'll Try a new resistor and see if that fixes is it. I assume to do the PCM method, the resistor could be removed, the original wires hooked back together and then go from there. Second question; how do I find out how to do the PCM tune?

    1998 K1500 5.7 starts then immediately dies

    My Suburban starts then immediately dies. Fuel pressure is good and I can hear the pump run when ignition is turned on. I bypassed the Passlock system about 3 years ago using the capacitor spliced into the wiring in the steering column method and had no issues afterwards. The security light is...
