Re: 87 blazer wont start
I checked all those things and they were fine, i took the fuel off and had someone turn the key on and i wasnt getting any gas out of it, i have put a new pump in like two weeks ago and a new filter.

Just turning key on is not a good fuel pressure test. Just. Key on only gives the fuel pump a 2 second prime up. May not be enough time to build up proper pressure You need to check for fuel pump running and for proper pressure with engine cranking. Does it run on engine cranking and what is fuel pressure?
