Ok guys i know this is pretty general to start with but i am not sure where to start with all of this. I was just driving down the road and the truck dies. I have spark, but no fuel pressure. I have a brand new fuel pump, and can hear it running but no pressure at the rail. after sitting a while i have pressure again, but still wont start. after very extended cranking at starts but lopes like a have a huge cam in it and very high compression. I unplugged the IAC to see if that was causing the issue with no change other than to just die completely and not start back up. when i had it running i attempted to frive it back home ( about 8 miles ) and the trans is in safe mode. Over drive light flashing, trans holding gears until i completely let out of the throttle, and the engine running extremely rich to where it looks like a diesel driving down the road. I may be wrong in theinking this here but i am thinking that my computer is pretty much toast, and need to replace it. I tried to pull codes, but since this happened it will not flash the check engine light for codes, and afraid to drive it any further to get a scanner on it if it will even read codes on the scanner. What are any ones thoughts?
