1993 Blazer fuel problem

check your fuel pressure should be 35 to 42 with key on engine off,and about 5 to 7 more with engine running and vacuum line off the regulator,also check your fuel regulator with vacuum off it should be dry if it is wet with gas it is bad

Check the crank case sensor

have you check the distributor?, I have had symilar problem with a newer blazer and it was the distributor, good luck

You might have a defective fuel tank pressure sensor!

Timing chain. It's probably broke!

first get it to crank, replace part of the fuel line with a clear plastic one, and install a fuel guage, fuel pressure shoud stay steady and no air bubbles should be visible, if all is good have a real time scanner installed to monitor sensors and actuators, good luck

Maybe you have a short in one of the wires at the fuel pump. If the pressure was low, it would probably stay low. There should be a bleeder that looks just like a tire valve. If not, remove the line at your filter and hook the gauge in there. It don't really matter where you put it, it should read the same anywhere. I guess if you wanted to spend the xtra time, ideally you could mount the gauge in the cab(run a "t" off of your fuel line) that way when it dies, you will see the gauge and be able to tell instantly.

check fuel pump for faulty ground.i had same problem and thats what it was,ground was loose,it was some times go and some times stall then quit till i had it towed and new ground put properly on

replace the distributor oil is leaking into the electronics of the distributor and shorting out pull cap back off and look and see if oil is leaking out

have the computer checked out. may need reprogramming and have updates added. also check for loose or corroded connections at the terminals.
