    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...

    Hi all, I am selling an intake/throttle body for the 60* V6 engines, modified according to the suggested performance enhancements noted on this site. The core of the throttle body is from a 4.3L engine, but the throttle linakge has been swapped to be compatible with the stock 2.8L setup...

    Hi all, I just completed putting my 1989 4.3 V6 262 TBI motor back together. It is running really bad, and sounds like random misfires. It keeps running rich and fouling the plugs. It sounds like it has a radical cam but it does not. It’s acting like plug wires are crossed, but I have checked...

    Hey, A little backstory on my s-series. I purchased it around 2 years ago from a private seller who bought it to fix up to sell. Apparently, it sat for around 5 to 10 years before he bought it. I purchased it and only replaced three sensors in it being the throttle position sensor, coolant...

    Looking for some guidance. I’m currently an automotive student in north FL. I have a 1992 2.8L S10. I’ve been chasing my tail on a crank-no start issue. My battery is fully charged. The truck ran fine, but I let it sit for a couple months while I rebuilt my transmission. After I reinstalled my...

  7. 2.5L - 1st gen 4-banging
    We didn’t a 2.5 swap from a 91 S10 into the wife’s Vega, and no start. Have spark and fuel to the tbi, but nothing from the fuel injector. I’m on my way to get a new one, but wondered what sort of signal it gets to operate and how to test that signal and the injector itself?
  8. S10 / S15
    This is just a crazy idea my friend and I got to talking about, anyways I have a 350 going to go in my '91. I was wanting to keep the TBI and just switch it over, obviously, change the computer and injectors. Then, I came across a dual carb tunnel ram intake, and I know they make adapter plates...

    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...

    so I’ve got this 1990 s10, 4.3l tbi. Truck idles fine, seems strong. As soon as I put it in drive and go to leave it’ll die, not stutter or sputter but cut off and die. I can feather it and it’ll SLOWWWWWLY climb. My guess is electrical. I’ll skip a lot of the reading and show what I’ve...

    I want to do a Factory Camaro TPI injection setup on my 350. I've seen it done on many S-Trucks in books and online but I have a bunch of questions: Somebody please help me out! Will a 85 TPI setup connect and work with a 94 4.3 CPI computer? Does the year of TPI matter? Will TPI work with the...

    I’ve had hell with a ‘92 2.5L S-10. Left it parked at the ranch for a couple years. Prior to that it has been my spare truck when the big diesel work trucks go down, hadn’t failed me in over 10 years, but alas, I ignored her for too long,... Started with fuel filter, (and fuel treatment...
