Won't start sometimes

firecadet613 · September 20, 2005

I've got a '95 Blazer with the 4.3 V6, with the CPI Injection, VIN W. About every 10 starts or so, it won't start up. It will crank and crank just fine. I'll pull the ECM fuse for about 10-15 seconds and put it back in, and it will fire right up. Next few starts are fine until it starts just cranking again. Anyone have any idea whats causing it or how to fix it?

Thanks!

could be a faulty starter or a bad solenoid.

You might want to check your fuel pump and make sure it is putting out the correct pressure. the CPI is picky when it comes to having high enough fuel line pressure for it to start... just a little off and no starting. what happens is that when you continue to crank, it gradually builds up enough pressure until it starts. i had the same problem on my old blazer and it was the fuel pump.
