93 chevy truck wont start

Try the best I can. I have a 93 chevy Truck that died one day I found the ground wire from the block to the body was broken. I have replaced that wire . it started but then when i turned it off wont start. have replaced pos. wire from battery to starter. a new battery, pulled the starter and jumped the bolts and the starter turns and kicks in. so this what i have when i try to start it it just clicks and everything goes dead. thats with a new battery to. oh ya one time when we worked on it we saw aspark jump from a bracket on the block. im about to pull my hair out please help. :banghead:

How about the ground from the battery to the engine block. Any corrosion anywhere. I know you have a new battery but what is the state of charge. Should be 12.6 volts. Do a voltage drop test on the ground from the battery to the block, no more than .3 volts should be seen with a voltmeter. Wouldn't hurt to do the positive from battery to the starter also. Check voltage drop while cranking the engine.

sounds like wire from ignition switch to starter solenoid is bad, bad solenoid?
