I need to know if a bad TPS will cause the car not to start. I have already replaced plugs because they were fouled and replaced wires because they were damaged.I have not found any other problems besides the bad TPS. It had an intermittent check engine light and rough idle before it quit running.
Do you
have the same problem?

A bad TPS will not prevent the engine from starting maybe idle/hesitation/stalling problems-Do below to determine if its fuel or spark problem.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil, distributor pick-up coil, ignition control module, cam and crank sensors-

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

I have spark and the engine is flooding. So I think the car has a timing problem so how do I check for timing problems and should I also run a compression test. The car makes a loud hollow thumping noise when trying to start.

I found the problem the timing belt tensioner was loose and caused damage to the theeth on the timing belt. The engine was recently swaped before I bought it and timing tensioner was not fully tightend.
