Mine actually needed software downloaded into it. My crank sensor was good. I downloaded what they told me to and it fired right up.

Hey guys. I've read through a lot of this post and it has a ton of great information. I have had the system running a 5.3 in a 95 chevy 1500. The one thing I am trying to find some info on as I have 70051 with the trans control is where do I find the line pressure table for the system. I have been looking in procal without luck and after watching the line pressure while going down the road the output value is clearly not right as it shows a value of 7 for final line pressure. Any one have any inf on this?

pull the fuel pump relay and replace. Maybe the relay locked up.

I ended up having to replace the ecu :.. (...on the nova, but now I havea new problem on my c10...I swapped the glass packs for flow masters and now I'm getting a code 56 and 137.....do you think the asa cam is not getting along with the restricted mufflers now and thus that is causing my o2s to get choked up.......it wierd though cause the truck seems to run fine!!!!!

Picked up a Dakota Digital dash, Tanks setup and nice looking set of Headman headers..

Engine and trans are sitting in my 73 F Body
