Hello all! I’m at it again with the 0411 PCM swapped LT1,
got everything installed, got fuel, it cranks, but no fire.
a little about what has happened since I first started driving
with this PCM swap. Here in Missouri, about a month and a
half ago, we had a really bad cold snap, I was right in the
middle of getting this thing tuned and it died on me while
driving home. it back fired twice, and would not fire back up.
Once I pulled the engine out, I started finishing the assembly
of my 383 engine. I found the reluctor crank key had sheared
the corner off the key, causing the wheel to turn. I installed the
reluctor wheel with a new GM key, and re-installed the balancer
With an installation tool.
fast forward to yesterday. I got the car cranking,
have 12 volts to the coil, but no fire. Could my
ICM have gone out when the car died? I have another
I’m going to install, hopefully this will fix the no fire condition.
let me know what you guys think.
thanks!

p.s. I almost forgot... I went to Oreilly auto to get a new
oil pressure sensor, the one I got has 4 pins, and my
oil pressure gauge is pegged out high now.
does anyone know which terminal of the four I am supposed to use?
the GM dealer told me the original sender was discontinued,
so I ordered the new one and it has four pins vs three.
now what
