    No start no crank! All electric works.

    Fuses are good. I checked those right after the no start. I'll check on those wires for corrosion. Im in seattle now, but spent the last 4 years in Michigan, so that makes sense that they may be bad. I'm sure their stock too. For the voltage drop, i test it with key off and then key in on...

    No start no crank! All electric works.

    So hook the jumper cable to the connection points between battery and ground and then try to start it? If starts then I would need to replace that wire? Obviously check if the surface is good for the ground, but if that's good then i would need to replace the ground wire? Thanks for your help!

    No start no crank! All electric works.

    Hey there GMT400, I have a 1994 Chevy Blazer 5.7 tbi. Couple weeks ago I had a no start no crank issue. All lights and electrical work. It had a little bit of a rough start in the weeks leading up to this - slow cranking. But always started. I assumed starter and had a new 95-up starter...

    Intake Gasket Replacement - Advice, anything else?

    ^ This for sure! Always happens especially on high mileage engines. This was definitely the worst part of replacing my gasket. Luckily I kept it connected when I removed my intake, so when mine snapped and I had to fish out piece by piece, I wasn't dealing with the metal falling into my block...

    help! TCC error (code 38)

    Well damn....still no fix. On Monday I decided to take a look at my brake switch under my dash. Unplugged the connector, pried off the retainer clip (pain in the ass!) and slipped it off. Pretty gunked up as well as a black contact point, so i decided to change it. Brand new one in, and no fix...

    Full front LED’s with LMC Truck clear housings

    Another seafoam question

    Do you know if you have any exhaust leaks? I know this sounds dumb, but back when I had little leaks from the manifold and right before the cat and then a large muffler hole, when I would do my seafoam treatment, I barely saw any smoke. I think it just dissipated with all the leaks and seemed...
