95 Chevy Astro Cranks, Won't Start	Sign In

95 Chevy Astro 4.3L V6 approx 150,000

Vehicle sat for approx 2 yrs

Replaced fuel pump. Pumps fine.

Pressure test - 60 - 65 psi in 'ON' position/ on crank

Tested injector pulse - tested normal

Sprayed started spray in intake, did not start.

Cannot figure out what to check next, maybe regulator? Any direction would be greatly appreciated.

Thanks!

Spark and compression are the 2 things you haven't tested yet.

Thanks.

I was reading compression has to be tested on warm engine, is this true?

Since I can't get it running I wasn't sure I could do compression test.

It would be more accurate but we are just looking for sufficient compression to run. You only need to do that is you find no problem with spark. One of the functions has to be missing or have some type of problem.
