MAJOR issue with my 95'. Any and all suggestions welcome! please!
Theres a very long list of things its been doing and ill try to keep it as organized and easy to read as possible.
- 95 blazer s10 4.3 4x4
- When I first turn the engine on there's a 50/50 chance of it actually turning on and not immediately dying afterwards
- When the engine doesn't want to start I have to immediately begin giving it gas. And I mean a lot of gas or it won't stay running. Basically if my rpms aren't constantly going up. It will begin dying.
- While its running an I drive under 20mph(generally just driving slowly, such as turning, red lights, ect). The engine will die.
- If I drive around 30+ mph its usually fine but sometimes(depending on how big of an ******* my truck feels like being) it wont run no matter how much gas I try to give it. It literally does nothing when I step on the accelerater. Once it sits for a little bit(doesnt matter if the engine is on or not.) It usually starts up but I have to slam down on the accelerater or it will immediately die.
- The truck also 'kicks' I guess is the word, while driving, the kick is the engine trying to shut down.
- Occasionally you'll get a huge smell of gas randomly floating around.
- Before any of this happened when I fill my tank up with gas it backfires a little bit when I give it to much gas(going up hills is the major cause, even a slight incline). But backfiring is only temporary and goes away after ive drove for awhile.
- It would randomly backfire going up steep hills even if its been days after putting gas in.(This is rare but would happen even few weeks/months then just stop.
- Sometimes it wont even start and the engine just keeps pumping like its trying to but other times it starts up no problem.
- All power stays on besides engine, brakes and power steering.
- It sits in neutral and park just fine( unless its on an angle with the front end being pointed upward, then its harder to start).
- No check engine light
- No codes to display
This all randomly just happened out of nowhere and gradually just got worse. The only thing that I did before it started happening was jiffy lube topping my oil up for me. Then it sat for a few hours and I got dropped off and it just happened.
Things I've tried.
- Checked for vaccum leaks
- Replaced fuel filter which I thought helped but it could have also just had a random moment of working which it sometimes does.
- New battery
- Cleaned egr valve
- New spark plugs and wiring
- New air filter
- It still has its catalytic converter on
That's about as detailed as I can get on it. Ill update if I think of anything else. I'm desperate. This is my only means of working. Please help guys.

Yup, check fuel pressure and leakdown first. Key on, engine off, fuel pump running, (first 2 seconds after turning the ignition on) pressure must be 55psi to 61psi. It must remain above 50psi for at least 10 minutes after the pump shuts off. Post your results.
