New Parts for Old Trucks
I recently had to swap my hydroboost unit out since it decided it was ready to throw in the towel . No big deal , easy r+r .
While it was out i decided to reroute some engine bay wires and to do that i needed to extend my tps and iac plugs .No big deal , one by one each was extended just a couple inches . Finally done looming and black taping everything , zipties here and there so it all looks good and figure lets get this pig rolling . Well no dice .:tdown:
First attempt it did start up , but was running off with slight backfire . I was like wtf ... Close inspection revealed i swapped to pass side plug wires on the dist cap , so easy fix i put them back to the correct order . Now i start it up , it starts but will not stay running for more than a few seconds , then shuts off by itself .
After looking around in tp with key on , but not running i notice wb02 data was not being seen by the ecm . It was showing on the LM-1 controller , so i knew it was just a loose wire . I traced it back to the connection under the dash and wouldnt you know right where i had to squeeze my arm up for the hydroboost bolts , i had pulled apart a single butt connector . Thinking all was well , i fixed the connection and last night went to bed .
Thinking i was in the clear , today after work i decide to take the truck out for a spin .....
Now the truck shuts off and dies everytime i pull it out of park and attempt to drive , no few seconds of running , just as quick as i hit reverse from park it dies . I tried starting it in neutral and then going to drive , but same process over and over .
I have way to many things to finish before nats and this is a monsoon on my parade ..:rant: I did a datalog while starting and idleing to show whats happening , and even tried a few different bins while logging to see if maybe the bin was bad , but each time , over and over , the truck dies when i try to drive it forward or backwards .
I saw nothing overly obvious in the log, so i am here asking for help . Here is your chance to be my new best friend and save the day .:tup: My log is below , im open to all ideas ...
