2002 year model 4.3lrtsee said:I have spark, 55psi fuel pressure. When you turn over it sounds like it trys to start but won't. Car sat with dead battery for 3 months... help...
the roadie said:Maybe the fuel's not getting into the cylinders. Try starting fluid (ether) into the intake to see if it catches at all. Combustion is simple. Fuel, air, spark. In the right proportions at the right time, to be sure.

I know you said you have spark. but I am willing to bet it is weak.
Inspect the cap and rotor. No matter the quality or manufacturer, I rarely get more than 13-14 months out of a set. OEM, Delco, aftermarket, zero difference.
