I considered fuel pump / fuel filter / fuel relay, but none of those would explain why the starter does not continue to turn over until the engine starts. Use to be that I clicked the key over, let go and the starter would continue to crank until it started. Now, the moment I take my hand off the key, it stops turning over.
How does those switches work anyway? Seems to me like an electrical problem related to that switch.
Your ignition switch/starting system is different than any starting system I've ever seen. (and no, I haven't seen them all!) For manual starting systems (no key fob or auto start) the engine should only crank when the key is turned to the start position and then stop cranking when the key is released (to the "on" position) whether the engine starts or not.
If you can confirm that there are no fault codes stored, I would begin by checking for vacuum leaks under the hood in the engine bay, all the while suspecting that it could be the fuel pump or fuel pressure related. (which may require the removal of the fuel tank)
How many miles on this vehicle?
