I have a 1987 hard body Z24 with a manual transmission and it won't crank on it's on but if you take the breather and air filter off the TBI and spray starting fluid down in directly into it then it will fire right up but will not fire up on it's on with out the starting fluid and runs fine after it cranks up while ideling but if you mash the gas pedal to the floor fast while sitting still or wind it out before shifting gears it's starts cutting out like it's trying to run out of gas
