won't start

What type of tranny do you have in the car - auto? If so, if the neutral safety switch is not working, or is mis-adjusted, the starter is disabled. Try putting the tranny in neutral instead of park and turn the key. Still nothing? Move the lever back and forth while holding the key in START. If it even bumps the starter once then fix the neutral safety switch/adjust it.

 

Also, the factory alarm disables the starter link. Quick "reset" method: use the ignition key to lock and unlock a door. In theory, unlocking the driver door is enough but, since that's the one that gets used the most, the alarm cancel sensor in that door tends to fail first. Try locking and unlocking the passenger door, then see if the starter engages.

 

Otherwise, you're down to tracing wires. The circuit to the starter solenoid is fairly easy:

battery + post --> IGN fusible link --> ignition switch input post --> ignition switch START post --> small wire at solenoid.

You need to trace those points, looking for +12volts on each one while holding the key in START. When you get no volts, you've found the break in the circuit.

 

A missing ground strap on the engine block will also lead to a no-start because the starter motor can't ground well enough for the huge current draw it demands. Other ground wires try to take up the load - and burn out like fuses. The throttle cable ends up being a ground and it burns up, welding the cable to the protective sheathing... destroying the cable. The engine block ground is bolted to the driver side of the block, near the alternator. On rebuilds, shops paint the blocks... if you didn't clean the paint off this point before installing the ground strap then that's the bug.
