Beating my head against a wall here. Car sat for about a year and now wont do a thing. Can run fuel pump by jumping the relay, can crank with starter relay jumped. No spark at all, no fuel getting to engine. Fuel pressure at 60+ with pump running. Hotwired ignition switch connector and get radio, crank, and fuel pump but no start. Whole time gauges do absolutely nothing. Really want to get the car going again. Any ideas?

 

sounds like the antitheft system is engaged. look at 26 27 28 here 4th Gen LT1 F-Body Tech Aids

 

I doubt it. Disabled vats in tunercats, tdr bypassed, and has a resistor in the key line. Fuses are also all fine.

 

check your ignition switch make sure you got power goin in and out.
