My 1998 Blazer won't start every time. Fuel pressure is 65psi, I am getting strong spark from ignition system, and there are no codes from diagnostic check.

If you have fuel pressure at the rail and good spark, you need to check for an injector pulse. You will need a noid light to check that. Even though you are getting fuel pressure, if the injectors don't inject fuel, it won't start.

Whjen this happens again, see if it will start with starting fluid.

Let me know what you find.
