LT1...no fuel??
The injectors are getting power and are pulsing on my LT1, but I'm still getting no fuel coming out of the fuel injectors. I pulled the fuel rail off (with the fuel lines and everything still hooked up) to see if we could see fuel spraying out of the injectors. No fuel was coming out of the injectors.
I hooked a test lamp to the positive battery terminal, and injector harness. Im' getting a solid power on one terminal, and I hooked the test lamp to the negative battery terminal, and I'm getting a pulsing on the other injector terminal.
I have a brand new fuel filter and a brand new fuel pump. There's plenty of pressure in the rail ( I don't have a guage, but there seems to be plenty of fuel pressure.)
There is spark, and seems to be compression. It still won't start, and I'm thinking it's because of the injectors not firing.

Well I found out that the injectors were getting power..but not enough amps. So I did some re-wiring, and voila!! The beast starts!!!
