I have a 78 280z, took the motor out with a few friends, we rebuilt her and droped the motor back in 3 months later but it wont start, it cranks over but wont start. we ran test, it has fuel, and spark but it wont start. The test show the spark is bit weak from the coil. Now also we hooked the starter up exactly the way it sapose to from pictures took before uninstall. but now the starter turns with out having foot on clutch and it sounds week. we took it up to a auto zone, ( i must mention, I hate auto zone lol), they tested it and said the starter is still good. Would a slow turning starter be a issuse, is there any thing u think i missed hooking up that would provent it from not starting, Any help would be very very much welcome. This is my first Z and I love the car and i only got to drive it for 3 weeks before we was forced to tear it down.
