My gle740 is not getting fuel to thruttle body but getting it to feed line to bars i cleaned thruttle body but still nothing . How can i fix this

Check to see if power going to fuel injectors with a noid light. If no power bad injector relay or PCM.

Ihace power to black box on thruttle body and have fuil to rail and fuil presure reg it turbs over vut wony start i spray it and starts then dies

If you spray into throttle body and it starts you are not getting fuel through fuel injectors they are not getting power that's why I suggested checking power to injectors.

usually the ground on the injectors go out for lunch, check it there is a pulse when connecting noid light to ground(battery negative) and the other point to 1 of the injectors terminals.

Brand new brain brand new distributor brand new knock sensor brand new mass air flow Still doesn't throttle

Injectors are fine
