Help please: 95 Northstar no start problem

[Frank Bongiorno]

I've installed 96 northstar engine in a fiero and just finished up
swapping the pcm plugs from the 96 harness to a  95 pcm setup (BMFY).

My problem: The engine cranks, I have spark, but the injectors pulse for
one rotation and then quit until I unhook the battery (then they pulse
again and shut down).

Some notes:
- The fuel pump turns on for 6 seconds and shuts down until I start
cranking.
- The injectors never loose power
- All connections are soldered and shrink wrapped.
- I have a ALDL interface but have been unable to find any software to
read the trouble codes.

Also, "I think" the vats is disabled in the chip I'm using. I've copied
a friend's chip who runs without a vats but his Vats Wire is showing 5.5
volts when not connected to the PCM so I applied the same voltage to
mine. I also measured the voltage coming out of my pcm with no wire
connected to it and it's 5 volts as well (The books says it should be
2.5 volts).

Any thoughts/suggestions would be greatly appreciated.

Frank
