1993 Bazer 4.3 fuel problem

Hi I have a 1993 S-10 blazer 4x4, I am having a problem with something to do with my fuel. Sometimes in mornings I start it , It takes 3-4 tries before it starts. But after that its seens to do fine, I drive it and sometimes when I go up hills it starts acting like its not getting enough gas and starts sputtering and popping under hood, I can turn key off and restart it and it runs great after that, that always works until maybe next hill and it does it all over again. I have replaced the following. Fuel filter, plugs,wires , dist cap and rotor button , air filter , pressure regulator . Can anyone help me I cant afford to keep guessing to whats wrong with it. any appricaition will great.

    Hi Thanks, I had a local garage do a fuel pressure test this morning and he told meto start it up, when I started it up the pressure goes to almost 60 then it drops way down to like 10, so he told me to get a new fuel pump and see if that takes care of the problem. Thanks for help I will let ya know.

    I have another question, are you supposed to hear the fuel pump all the time?

Have a '94 S-10 Blazer Tahoe 4X4 and it starts

My suspicion is a starter going bad. Sometimes when starters get old and worn they will start good when the engine is cold but not when the engine is warmed up. Did you perhaps notice that lately is seemed to drag when you tried starting, especially warm or it seemed to crank a little slower? I'd replace the starter. Hope this helps.

1993 s10 4.3 starts fine, while idling it dies. sometimes i have a hard time restarting. the blazer died a couple of times while driving.fuel pump is good, tuned up, remanuf. injectors 1 yr ago,engine lite...

only half way there if you have a tbi check the crank sensor/ cam sensor that is the first line of business on that truck if the crankshaft sensor fails the truck stops dead when you wait a few minutes the sensor re energizes and the truck will work again for a bit antiknock can cause similer problems but not while the truck is running

I would make sure the spark plugs are in good shape and also replace the fuel filter every 35000 miles.

Gas in the oil and in the exhaust

spider type fuel delivery inside upper intake known to leak , and with repeated attempts to start , fuel gets into wherever gravity will allow , be sure to drain fuel soaked oil before attempt to start after repair and because fuel is in the exhaust , it might blow the muffler and melt the catalytic converter

Transfer case motor for push button 4x4

i have a 1993 blazer 4.3 w code 4x4 with a 4L60 E . my truck wouldn;t go in 4 hi or low. so i changed the transfer case motor and it works fine now. If you turn the ignition key to on but not crank the engine and open the driver door and push 4 hi button, you should hear the transfer case motor cycle for 3 or 4 seconds every time you push button and the light will flash until it goes in 4wd If the 4 hi button light doesn't flash during cycle then it could be a bad switch. if the transfer case motor won't cycle it could be a fuse or a bad transfer case motor . Hope this answers your question.

Won't stay running

sounds like fuel delivery, sometimes check valve in fuel pump will quit working and fuel will drain back into tank, or pin hole in one of fuel lines, check fuel pressure
