Cranking No Start...Ignition fuse?

If the ignition fuse 15A in glove compartment is removed, should a car start up? If not, in general, what does a successful start up without an ignition fuse
indicate? Specifically, car is a 1995 Chevy Lumina Van 3.1L, V6, 108,000 mi. Always cranks, intermittent starting. As yet, pattern is unpredictable. Troubleshooting continues. Voltage drop over time, from >14V to nearly 12V.

Had similar problem in my truck. Cause, ,bad fuel pump. Was not supplying the correct amount of pressure at all times...ESPECIALLY at start up.

Troubleshooting continues. Voltage drop over time, from >14V to nearly 12V.

The ignition module in this case was at fault. Upon replacment, car starts nice.
