I just bought this truck. Manual 5 speed with 4 cyl engine. Wont alway crank.

What is your question?

I put the key in, push the clutch to the floor, turn the key to the start and it sometimes does nothing. After several tries it may start up fine. The starter turns fine. Is this an ignition problem, clutch swith, or solenoid? Truck only has 49,000 0n it.
