    I need to know the name / part number of the location where the fuel lines go into the intake manifold. I believe this is a CPI / spider fuel system since the fuel lines aren't directly connecting to the carb. The throttle body also appears to only have one large flap vs some I've seen with two...

    Sorry for the long post I’ve been trying to diagnose my stall/ no start problem for a while now. I need some expertise. Vehicle: 1989 s10 (2.5 tbi) 2wd w/ 5speed 80% of the time it won’t start on the first 5 attempts or not at all. 19% of the time it will start and die a few times then run if...

    I replaced the injectors today with a used injector set because the studs for the 8mm bolts broke off. When installing the new injectors 4 out of the 6 had a click feel where they need a little force to pull back out but 2 will not click into place and I pushed down as hard as I'm comfortable...

    1992 S10 Blazer 4x4, TBI 4.3L Engine cranks. I have spark. Engine acts like it wants to start, almost starts to run, and just immediately dies once key releases. I've tested fuel pump relay, ignition coil, pick up coil, control module, etc, etc. And everything else I could think of to look up...

    Please someone anyone have a solution. I’ve changed fuel pump, fuel filter, and spider injector all within three days. So now here’s the kicker it still doesn’t run. Put some gas down the throttle body and she starts up keep up the starter fluid and it keeps running stop and it dies out again. I...

    Hello, My 2002 4.3 95,000 miles runs like a champ, I've done a ton of work to it. Just came back from a trip that added 1200 miles. Issue I still have with it, I often need to crank it twice to start after its sat overnight. I can hear the fuel pump kick on and the fuel filter has been...

    Looking for some advice. Inherited a 2000 Sonoma 2.2Flex Fuel from my grandfather. Last time it started was 10 years ago. Since getting the vehicle and in my attempts to get it running I have replaced the Battery, Fuel Pump, Fuel Filter, dumped the old gas from the tank, put good new fuel in...

    1987 S10 Blazer 2.8L V6 4WD So when I first got my S10, the distributor was worn out and was off just a hair but it wasnt entirely noticable. Just last sunday (05-15-2022) I changed the distributor without a timing light and did the best I could with just the timing marks on the camshaft...

    Hey yall, I have a 1988 S10 extended cab with the 2.8L V6 fuel injected and when cleaning the engine bay I noticed some gunk that I thought was a melted gasket in the throttle body. I took a look at it and it appeared to just be some dirt and other stuff that had built up but I noticed that the...

    Hello everyone! Proud new member here. I have a 2004 S10 Crew Cab flavor. She left me stranded on the side of the road and I went ahead and checked for fuel pressure and sure thing, nothing. A guy went ahead and ripped the tank off and put in a new fuel pump assembly (spliced in new connector)...

I have a ‘90 s10 4.3l tbi, I’ve been looking into braided fuel lines that are -6an PTFE and everything but I want someone’s opinion on what they have done or know can be done. Any links would be...

I have a 1985 Chevrolet S10 Pickup V6 2.8L 4x4, and when removing the varajet 2 barrel carburetor to replace it I broke the fuel line. I have been looking everywhere for a replacement for the fuel line...

    Hello. Ive got a 1990 s10 4.3l tbi I’m slowly working on and one of the feed lines attached to the back of the carb was severed, i think someone bent it when removing the carburetor, it runs down and the rubber end slides over the other fuel line that goes into the frame. Following so far? so...

    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...
