My 940 Turbo sedan has just developed the problem that it suddenly dies and then is hard to start. I read the codes and got the 3-1-2 on ignition and 1-4-4 on EGR. That's great but in my Chilton manual it does not give guidance what to do next. Can anybody help out. What is the EZK and what does the message about the wiring break mean. Is it simply a faulty fuel injection relay.

3-1-2 Signal missing for knock-related fuel enrichment Wiring break between EZK terminal 4 and FI #28

1-4-4 No load signal from fuel injection system Bad fuel injection relay; faulty wiring from LH to EZK; bad LH module
