Can a TPS sensor cause no start?

The only way a TPS will cause a no-start is if the TPS is busted/stuck, and the TPS is telling the computer that you’ve floored the gas. The computer won’t pulse the injectors, because when you floor the gas (WideOpenThrottle) and crank the engine, the computer goes into “clear flood mode”.
