HI,

I am sorry that you have not been helped yet.

When it doesnt start immediately, have you tested for spark and fuel to see which is missing? If not, you need to do this first, from there we know the area to test - fuel or secondary ignition

Expert:  cloe0626 replied 1 year ago.

ok it said you had a phone call request in it sounds like you have a dead spot in your starter i would start with testing the starter

Customer: replied 1 year ago.
i just sent a message your answers are stupid or you didnt read the problem
Customer: replied 1 year ago.
the starter works just fine i am inquiring about this problem becase me and other mechanics cant solve thats why i asked .but telling me the starter is the problem when i said it cranks over for unlimited times for 8 or ten times without starting i know better that its not the starter come on.
Expert:  Mike S. replied 1 year ago.

It sounds to me as though the engine is flooding. That should have a clear flood mode. Next time hold the gas pedal all the way to the floor when trying to start. If it starts fine like that, let me know cause that would confirm tat it is flooding and the next step would be to retrieve the computer codes and check the fuel pressure. I know you replaced the fuel pump and the regulator, but it could still be something wrong with the fuel system and/or a sensor, thus the need to retrieve the codes also.

Customer: replied 1 year ago.
there are no codes showing up. i tried gas petal to floor does not work. i know the check engine light works it comes on with key on.i never seen a situation where you can crank the engine for 15 to 40 sec. wait crank engine about 7 times then it starts. if i shut off after that start it starts right up. if i stop a couple places after that it goes right back to no start. replaced everything from fuel line to engine even gas cap fuel filter pressure sensor on gas tank fuel pump what i dont understand why i am not getting any codes from computer

Feel if that relay is loose in the socket and if not, go ahead and replace it.

Customer: replied 1 year ago.

Expert:  Mike S. replied 1 year ago.

The fuel pump relay.
