740 Turbo problem ... again.

Post by 1990_740Turbo »

The mechanic i was seeing noticed my alternator belt was on backwards and the adjustable pin was broken in it. They fixed it , and it ran great ... until i got it to my house. Now it won't crank. I did a OBD check on it, and i got a 3-1-2 in the number 2 socket, meaning Signal Missing for Knock-Related fuel enrichment which is the cause of - Wiring break between EZK terminal 4 & FI #28.

How can i work on this, and wtf does it mean.
