I have a 01 Blazer 2dr, 2wd,5spd, 4.3l, and the original motor blew up so I put a 4.3 from an Astro Van in it. The van was running perfectly fine before someone rear-ended it, and i was able to snag the motor. The van was automatic but everything looked the same, i plugged everything in, and...

Okay here’s the deal. I’ve got a 1994 ZR2 CPI. Over the course of the past two weeks I’ve installed new distributor, fuel pump, both knock sensors, injector assembly, fuel filter, knuckle kit, egr block off plate, motor mounts, temp sensor, spark plugs, wires, upper and lower intake gaskets...

I could really use some advice from someone who has gone through this or knows what's involved. (PLEASE ONLY POST REGARDING ADVICE OR HELP!!) I got a customer with a 02 blazer ZR2 4.3L 4WD wanting to do a LS swap. Im doing this swap on clock so I want to make it as efficient as possible and...

I have a 96 s10 2.2l that had a blown engine. Pulled that engine and replaced it with 99 2.2l out of a s10. I kept the intake from the 99 and did some wiring so that all the sensors would match up (all sensors are showing up working on the scanner). Changed the crank sensor and put in fuel lines...

Hello! My truck has been throwing some mixed signals this year. At first she was giving me a P0301, so I changed all the electrical components (sparks along with the wires, distributor rotor and distributor cap). I also installed a new fuel pump and the air intake is in perfect condition (clean...

I know this sounds dumb, but I don't know how many fuel injectors to order. I have a 1992 S10 with the 2.5L 4cyl RWD 5-speed, ext. cab. I know there's not 4 because it has TBI but after trying to find how many, I can't find anything for this specific year whether it has a single injector or...

I’m planning to buy another 4.3l v6 non-vortec for my 91 s10. I’m going to put a new cam, pistons, connecting rods and a TorqMaster SuperCharger since all the bolt patterns are the same. Maybe 50 shot of NOS in the future. How do I make sure the new engine is the same as the old engine? Meaning...

first off this is my very first forum visit and account. Usually google has lead me right, not this time. 99 s10 2.2l 260k this morning ran fine came to a stop sign and upon acceleration got some sputter, powered through that. Work was 3 mins away. When i parked at worked sounded like my ac...

so I recently changed the intake manifold gasket and I changed the oil from the milky coffee to fresh oil but my oil pressure gauge doesn't move when I start the truck. It wont move at all. Could this be a gauge issue or an oil pump issue? The truck doesn't over heat anymore and seems to idle...

Hello all! I have a 2003 gmc Sonoma 2.2L with a 5 spd. It runs fine and idles correctly, most of the time. Sometimes (usually on startup) the motor will bog down to about 500-800 rpm then idle back correctly. Other times it will happen when I’m coasting or pulling into neutral. Is this a huge...

I have a 2000 s10 zr2 blazer with the 4.3L Vortec Only code is P0303 Due to low pressure issues and backfiring I picked up the engine and transmission out of a 80k mile 2000 gmc jimmy and my father and I swapped both in. We replaced all spark plugs and plug wires, new cap and rotor, complete...
