Default spark+gas=no start???

well in my case it does....i've got 35 psi at the rails, i have spark, but its doesn't start?? The spark appears strong, it sounds good and is yellowish in color. is that a common color, or should it be blue? could the timming have jumped? it was fine when i parked it....

Do you have a noid light? You can test the injector harness to make sure they're trying to fire.

Timing is off.

A car needs three things to run
1.)Air
2.)Fuel
3.)Spark

Is you have all three, you should be good to go. With timing out of range, then the spark and/or fuel isn't coming in when and where it's needed.

Are you having postdetonation/predetonation issues? I mean, does it try to start at all?
