Hey guys im new here and i need some help. Okay my blazer will start for about 1-2 minutes then it dies and it wont start for another couple of hours. Just replaced the fuel pump and filter a week ago. Im completly stumped now. Turn the key to the on postion and i can hear the pump turn on, then pulled the fuel line off the filter on the engine side got covered in gas so its not clogged. I checked those then i got it to start at idle the passenger side injector was a little clogged but was fine once i reved the throttle a little bit. It ran for about 2 minuets then it stopped getting gas, so i loosend the fuel line to the back of the throttle body to see if there was still pressure in the line and there was. I dont know were to go from there. If anyone has any thing else to try i'll give it a shot. Thanks for the help guys.


PS: does anyone have a exploded view of the throttle body or know were to get one from. Thanks again

 

umm im not sure but i could be something having to do with the spider distributer for the fuel injectors- Take your question to s10forum.com/forum they will have answer for you right away (post it in the 262 c.i. forum)

 

It would help to know what year we are talking about here. It almost sounds like a security system problem where it can not verify the key and kills the motor. It could be something as simple as reprogramming your key to the truck (requires a dealer I believe) or it could be that the ignition is bad (place where the key goes). Both have been know to happen from time to time.

If you have verified fuel, then I doubt that it has anything to do with anything from the fuel taps at the intake back to the tank. Like I said, depending on the year, some of the newer blazers have an anti-theft system that could be malfunctioning in your case.
