Check the fuel pressure with a guage on it. Key on you should get a 2-second prime and the pressure should come up. If not check the fuel pump command with the scan tool under special functions.
There could be a blown fuse somewhere or a relay not powering things up properly. Do you have scan tool communication with all modules on the vehicle-??
Lots of basics to check first.
BTW, welcome to the forums. I hope I've helped a bit. There are lots of other good people here.....( I ain't one of 'em cause I'm CRUSTY-!! LOL) -
First Things First
Battery is fully Charged and Load Tested?
The First thing to check is fuel pressure
The ECM reads the fuel pressure and if it is in range about 40psi.
Then the ECM turns on the sparkComment
