suddenly my engine only cranks w/o starting. I can release the key, push the gas pedal once, turn the key to start and then the engine starts as usual. Is this a TPS problem or what?

Ha the check engine light come on? If not, it sounds more like a fuel pressure problem. Let me know about the light.

No check engine light. I replaced the fuel filter, which was clogged, but not stopped up completely. This made no difference in the problem. Ran a can of Seafoam through the fuel system. No difference.

I do have a fuel pressure tester. Guess I should try that to eliminate pressure problem.

If you have the tester, most likely you know how to use it. Here is a how to video if you need help.

Let me know what you find. Also, pay attention to how quickly the pressure bleeds off.

i have this same problem, and the pressure bleeds off really fast when i turn the motor off. Is this the pressure regulator? I have changed the pump and filter.

When checking the pressure, pinch off the rubber hose to determine if the loss if at the injectors or before the fuel rail.
