Blazer is still not running

[Ultrashock]

My 92 is having the same exact problems as listed in this thread....

http://www.automotiveforums.com/vbul...d.php?t=761151

After replacing the fuel pump, some leaking vacuum lines, replacing the computer (it shorted out when my old fuel pump died). The blazer will now run and drive when the engine is cold. I managed to drive it 8 miles before it died. Once it warms up it will start acting like its starved for gas, surge a couple times and stall out on me. It wont start up again until it sits for awhile.

My mechanic claims to have driven it for 80 miles without a problem after replacing the parts above. I take his word for it because he used up half a tank of my gas. Now its back to the same problems again........ any ideas??

If it ran 80 miles without any problems and is now acting up.
It is Back to the old drawing board.
How is the fuel pressure doing?
Is it losing spark or fuel pressure or injector pulse when it acts up?
Any codes showing up?

After a long time the blazer is finally up and running. The problem turned out to be a faulty fuel pressure regulator, and a bad fuel pump. After replacing both the blazer seems to be running smoother and no longer stalls.

Thanks for posting back how it went.
Glad you got it going.
I hope you are not using them Airtex fuel pumps.
Good Luck
