okay, i own a 1998 Blazer, 4 wheel, and it has 152k miles, Yesterday I went to walmart after school then came out and my blazer started fine i left and got a red light, it turned green i pressed the gas to go and it stalled, it wouldnt start?? I left came back an hour later and it started right up?? ran fine all weekend, then today i went to leave school and it started fine i put it in drive pressed the gas and it stalled again, i sat for a few minutes then tried to start it again and it was just cranking like the battery was dead but, i just bought a new one. Help please!! I replaced the fuel pump, i just got a new factory muffler, rebuilt tranny, and the catalytic converter rattles( i think somethings in the center but im getting that fixed soon). Please reply soon!

thanks,
Duffy

 

mine did this and it was the pump.. check your wiring harness... older GM pumps were a horrible design and they came out with a new harness that has to be spliced on when you change your pump... make sure those connections are good and dry.. corrosion will make the wire brittle and break.

 

mine did same thingi replaced pump also had pressure checked and it was good...thats why im parting it out because im not putting anymore money into this thing...2 mechanics told me that my prob was the fuel plenum...hope this helps u out.
