I have good fuel pressure to my rail. Good spark. my injectors worked good before the rebuild. i put new ring on them all. I checked my fuse at the box the efi was good. i dont know about the relay plug at the box? Im going to do a noid test on them thurday to check the harness. Is their an easy way to check the ecu?

 

I know this is an old post but wondering if you ever figured it out...I'm running into the same problem on my rebuild.

 

old! lol!

try tap tap tapping on your injectors...
