Car Only Runs When Starter Is Cranking
My freinds camaro stalled out when he was driving and now it will only run when the starter is cranking, once the starter stops cranking the car gets no spark. So doesn't the starter give the first spark? so then would this mean the coil is bad?
thanks
thanks

No Start
Check the distributor for 12volts (pink wire; on two wire connector) with the key on. If there's no 12v then the engine dies when you release the key from the start postion.
If it's not a wiring problem, then the ECM is missing a signal (like the (fuel pump switch; normal open, closed by oil pressure.)
There are other possiblities, need more info.

Point type distributor or electronic distributor?

OK, now we're getting somewhere. Most point type distributors have a ballast resistor that drops the coil operating voltage in order to prolong point life. This resistor is by passed during starting, providing the coil with the full 12 Volts for a hotter spark. When the symptom you describe occurs, it's usually because of a defective ballast resistor. See if you can find the resistor and check it with an ohm meter. It should read about 3 ohms.
