A freind of mine has put a 4x4i lump into their sierra. Not sure if its the 2.8 or 2.9 or what, but its refusing to squirt any fuel in through the injectors.

I said id have a look at it this week as my ka with ERST engine kinda of had the same problem, all be it different.

Was wondering if there was any known things with them? more than liekly thou im just gonna have to play with the wiring.sounds like theres now ignition live
