i checked the main relay and its still good getting voltage when hooked up to the battery. but when i turn the key to II i hear nothing getting voltage to fuel pump. jumped the wires so that the fuel pump would work and it still primes but when i turn it to 2 it doesnt do anything and cant hear relay but its working? this is causing my car not to start. and checked fuel pressure regulator and theres no pressure build up.... wth...

 

Check your fueses

 

so i look at my ecu and its not flashing the led once and no check engine light. so maybe thats it but how the hell can i check?

 

one blink means everything is ok and its on.

Check your fuses.

 

check the ground at the thermostat
