    My friend got into his truck (95 gmc k1500 z71 with 350 v8) this morning and turned the key and it just clicked. Jump started and nothing. Came back after school and jump stared it with better cables and it started right up. Let it run a while and disconnected the cable. Tried to start again. It turned over but wont start. Jump started it again and it started. Disconnected the battery to test alternator and it died. Tried to jump it again and wouldn’t even start with cables. Put a new battery in it and still cant get it to start. Poured gas into throttle body and still wouldn’t start. Checked for spark and no spark. We have power into ignition coil but not out. Replaced it and still won’t start. so we gave up for thee night. Any suggestions will be greatly appreciated. thanks.:help:

    check the icm in the distributor its what sends signal to the coil to fire and injectors to pulse. they are pretty cheap to replace
