92 Blazer won't start

Well, I got up in the morning and went to start my truck. It cranked over but didn't start. It has the 4.3 non-vortec.
I can hear the fuel pump come on and if someone tries to start it I can see the injectors spraying fuel. It has 11psi fuel. I also checked spark and thats good to. I changed the module in the distributor and the coil so far with no luck. I check for codes and only got the 12. I don't think it's the computer?
any help would be appreciated
thanks

Remove the coil wire going to the distributor cap and look for corrosion.

got it running, its was the timing I was out 180 degrees
thanks anyway

cool, enjoy
