    Oil pressure gauge issues, also need wiring info for sensor

    Awhile back I had a friend hold my wiring out of the way while I put in a new long block into my truck, we got it all bolted up, was plugging in wiring and noticed the oil pressure sensor pigtail was tucked in between the trans and engine. I snipped the wires since I didn't have time to mess...

    Slow cranking 5.7 Vortec... stumped here.

    Funny that I didn't even realize this was my post. Still having the issue. New engine, new starter, all new grounds, and battery cables. Still has the slow crank issue. Almost sounds like the battery is dead sometimes when you try to crank, it cranks so slow. I guess maybe that's just how these...

    Intake Gasket Replacement

    Under my lifter tray, it was so gunked up with black tar-like oil, I had to use a gasket scraper to scoop out the gunk, was like sand and grease mixed together, so bad lol. I'm amazed my truck runs as good as it does. Once warmed up, motor is as quiet as can be with great power. The girl I...

    Occasional slow start

    I've heard lots of mixed opinions about fuel pressure leak down speed. Mine leaks down extremely fast, probably 10 seconds, but my truck runs great.

    Slow cranking 5.7 Vortec... stumped here.

    Sounds good. I'll check out my cables and what not, Minnesota rust doesn't help things at all. And this starter is the Direct Drive unit, not Gear reduced. It was what was installed, so I could get my core exchange money back. Only 90$ after, though wishing I bought a gear reduction starter instead.

    Slow cranking 5.7 Vortec... stumped here.

    Awhile back I picked this truck up, and have dumped a ton of money into it, just to get caught back up on all the maintenance and fixing what has been neglected. Now when I first got the truck, it cranked pretty slow but had a marine battery installed. Being winter, I changed out the battery...
