Hi all,

I have good pressure to the fuel rail but no fuel injected into the engine. I am able to measure the resistance of the injectors and they are all good. I do not have a noid light to check the signal to the injectors. I checked spark and it is good. I primed the engine and it will start until fuel is gone.

Any help or suggestions will be welcome.

Thanks

Update:

The 20A ECU fuse is blowing as soon as the vehicle turns over. Is there any place I can get an electrical schematic for the ECU circuit or at least for the 20A fuse.

Also this is a 2003 Santa Fe.

Thanks

Problem solved. The ECU fuse was blowing because of a failed O2 sensor. I disconnect the sensor and the engine started.
