Good morning,

Does the engine crank over?

https://www.2carpros.com/articles/car-cranks-but-wont-start

Can you hear the fuel pump run?

Does the tachometer move up a little when you crank the engine? Trying to see if the crank sensor is sending a signal.

Was the check engine light on prior to this issue?

I do not see P0603 listed. Can you verify the code number?

Yes, fuel pump runs well, fuel is been sent to the injectors, but injectors won't open. No pulse from injector. Also have p0335, crankshaft sensor, I hope to change it again tomorrow and see if I can get a start. My worry is the p0603.
