I have a '95 Blazer 2-dr that I'm rather enamored with. I originally got it as a "beater with a heater" for the usual Michigan winter. Now, I kinda want to fix it up. I've already replaced the gas tank, fuel pump and float assembly, some of the fuel lines, both wheel cylinders and got new tires. The problem now? It won't start unless it gets primed. Gasoline, starter fluid or fuel system cleaner, it all works. IT starts right up and runs with no problem. However, turn it off and it won't start again unless it gets primed. I replaced the fuel filter since this problem developed as well as the cap, rotor, wires and plugs. Tomorrow, I plan to double check the timing. What else should I be looking for?

 

need to do fuel pressure leak down test may have a leaky fuel pressure regulator or leaky injectors

 

Sounds a lot like what my 96 did, and my issue was a fuel pressure issue. These trucks need very specific fuel pressure or they won't start. Check out this thread for detailed instructions on how to do the leak down test.

 

I'll probably work on testing the fuel pressure, or get it tested at my usual shop tomorrow. Today, I replaced the fuel pressure sensor, thinking that might do it. No such luck. Another symptom that I've noticed, when I get the truck started and hit the gas, it sputters and hesitates... almost to the point of stalling out. No backfire, and it actually straightens out when I get off the gas. I might be leaning more towards a timing issue. Any other ideas or advice would be greatly appreciated.
