    Bad coolant sensor pigtail

    So I am having an issue with a p1351 code on my 96 7.4. Was visually checking for bad wires and noticed the pigtail connector that goes to one of the coolant temp sensors is all chewed up. Are replacements available or can you just splice in new wires into the factory wire down the line where it...

    P1351, misfires and hesitation

    Hi. Recently got my 96 2500 suburban with the 7.4 running and driving. However it seems to be choking out when taking off from a stop. Seems to run fine while at speed but at times acts like it wants to stall when coasting at around 5mph. Did throw a p1351 code. Replaced...

    Stereo upgrade options/opinions

    I just went with new 6.5”s in the doors a 12” pre loaded kenwood sub and 5 channel amp to power it all. Hope to get it all put in once the truck gets back from the shop.

    Stereo upgrade options/opinions

    So in your opinion fitting the 6x9s in back wouldn’t be worth the effort? What about doing a set of components up front with stock size 6.5” in the back doors and with a 10/12” woofer in back for bass.

    Stereo upgrade options/opinions

    Looking to replace the factory head unit and speakers in my 96 suburban. I have pretty much decided on a kenwood Excelon HU. As far as speakers I am thinking replace the door speakers and run a single 10” sub. Opinions on amplifying all 4 speakers and sub or nix the sub and replace the doors and...

    Fuel leakdown

    Already replaced them with the bosh 4 hole. Its possible I didnt get them seated all the way but otherwise that shouldnt be an issue anymore.

    Fuel leakdown

    Idk haven’t checked. I know you cant pinch the metal lines at the regulator or along the frame. Is there a rubber line somewhere at the fuel tank to pinch off? I have never done any of this stuff before.

    Fuel leakdown

    So after installing the new injectors, fpr and distributor I finally have my 96 with the 7.4 running but I am still showing a fuel pressure leak down when key is turned off. I cant visibly see a leak up top nor smell fuel. What are some other possible culprits that can cause this?

    97 5.7 runs on 7 cylinders but won't on 8

    I needed to see that video. Thanks for posting. Helps me get a better idea of how to adjust the distributor. Plan to put in a new one today on a 454 so I have even less room to get to it. With any luck I’ll get it on the right tooth first try

    Injector install

    Supposedly they are same flow rate as stock just Bosch design. I don’t need the higher flow rate or added power for my purposes. Just trying to eliminate the fuel leakage up top and get the car running and driving

    Injector install

    I didn’t see anywhere they claimed to be new. Just not counterfeit. Website states they are fully serviced and tested but never new. No additional caps came. They were sealed in a bag, wrapped with some foam padding inside the box. They will either work fine or they won’t. Don’t appear to be...

    Injector install

    Ok thanks. Got mine from precision injectors. Had read several post that they were a good source. Also Five-0. Just chose precision. All the reviews I saw were good. Here’s hoping.

    Injector install

    Probably a dumb ? and some of you may think I’m stupid for this but that’s ok. Changing out the injectors on my 96 454. Are the brown cap looking things supposed to come off before puttting into the engine. The spray nozzles are exposed and they won’t come off just trying to with my fingers. I’m...

    setting distributor (cam retard) on 5.7 vortec with aftermarket distributor

    This is gonna sound dumb put when y’all say turn the distributor are you just turning the top half that the cap goes to or shutting engine off and pulling distributor completely and rotating the gear? Never done it before but will be putting a new one in hopefully this weekend. I believe I have...

    7.4 distributor/cam damage

    hopefully the obd2 scanner I have available can read it. If not then I may just have to have it towed to a shop that has the right tools. Trying to do it on a budget and do some myself. Getting a bit frustrated and feeling like I made a bad purchase. Only bought it cuz all my reading prior to...

    7.4 distributor/cam damage

    It’s got 284k miles. How much do those type scanners usually run? Most likely I will just try and get the timing close enough to drive it to a shop and have the timing set. I don’t know much of anything in the way of advanced mechanical work or what a lot of the data those scanners give you on...

    7.4 distributor/cam damage

    I have ordered a cheap scope to try and inspect it. Have a new distributor on the way. Just replacing the whole thing because I have no idea if the old one is any good or if it was just the gear that’s bad. Hoping the cam is fine. Really don’t want to dive that deep into it as I am no mechanic...

    7.4 distributor/cam damage

    Hi everyone. New here. Recently purchased a 96 2500 suburban with the 7.4. It was purchased with a crank no start. Guy said it had a hot start issue then quit running one day while driving. So far I have replaced the coil, crank shaft sensor, plugs, wires, cap/rotor and icm. I am currently in...
