Blazer wont start

96 Blazer 4.3L

Replaced radiator, started immediately and ran great for 1 1/2 days. Car sat in parking lot for 8 hours now wont start. Put key in ignition...nothing happened (all dash lights came on). Had battery checked was told it was bad and replaced it. Same thing, put key in ignition...nothing not even a little noise from starter. Could I have loosed a wire or something ?

Check the wire going to the starter.

Do you hear the fuel pump prime?

Do you have an alarm? (Aftermarket or stock) If you do, it probably has ignition kill. And if it does, that might be your simple one button pushing, fixer. get in and unlock the doors, with the remote and the power D/L switch. Then try it. No gaurantees, but it worked for me. This was however, when I was fairly new to my Blazer.

Yes fuel pump is priming.

No alarm.

I would check fuel pressure.

It shoud be 61-66psi when the key is first turned on to the on position before start.
