1995 chevy blazer stalls wont start after?

Question

I have a 1995 chevy blazer when cold it will start and run for 20-40 miles but then it will start to sputter and unless you keep it at an extremely high idle in neutral it will stall and even then it will eventually stall and you can start it back up without starting fluid for hours. the fuel pressure from the schrader valve is great. I have replaced the 02 sensor, maf sensor, tps sensor, rotor button, icm, ecm, the idle air control module. but im stummped what else could it be? any response is appreciated just need some ideas.

Answer 1

as you know it could be alot of problems and theirs alot more parts you could replace but that wont fix it get a code read out on it see if their is any codes thats why you have a dlc to communicate with computer to tell you whats going on if somethings a miss trouble codes are a great help if their is any



no codes then starts simple work up check the fuel filter check for vac leaks the problem would probably happen all the time but check i dont know how it runs i cant hear it so go from here and does it run bad does it sound like it misses or runs rough i know their is no codes but start simple i should have sad fist check ignition plug wires check connection to icm just to be sure then go on check connections on the engine and so on make sure you have good connections every where be 100 percent sure as it could cause for an intermittent issue do you know how to check the connections just looking at them wont do it

sounds like a vaccuum leak or your egr valve is stuck open.
