Won't start. Sometimes after I turn the ignition on (but not cranking) in order to pressurize the fuel system, I can do small "bump" cranks and then it starts. Then it runs for 2-3 mins, quits and then won't restart. Very frustrating. This is especially evident on cold days.

 

Sounds crazy, but your fuel pump could be freezing. Try tossing a few squirts of that red bottle ethanol deicer in see if that helps. If it works try changing your gas station.

 

before that I would do a fuel pressure and leak down test.

 

Went out to try to start the blazer today since it was sunny & 40*. After turning the key on, no ignition, I noticed the fuel pump was not turning on. Swapped the fuel pump relay with the AC relay and voila...problem solved.

 

my old 84 s10 blazer { well known as the turd }anything below 30 deg likes too be tied to the shop via elect cord. without she might start or most likely not - be the first winter the rx toy will be together so we will see on her - but she has the nice warm shop too live in when shes not out and about......
