Well some new info. It is a 1992 940 turbo. I posted it here on the 700 page by accident, but it has the same engine as my 740 turbo wagon. I checked the codes for it. As far as I can tell it has the Bosch Fuel inj system. When I checked the code it gave me a 3,1,1 this is a missing speedo signal. This can obviously be caused by the improperly working speedo. Then I checked the Ignition and got a code of 1,4,4. The Bosch section did not list a code for that one but the Rex/Regina did. It advised it was "No load signal from fuel injection system".
Causes from FAQ pages said Bad fuel inj relay,
Faulty wiring from LH to EZK
Gad LH module
What is a LH and EZK.

I'm not sure but am I working with two problems on with the Fuel inj from the spedo and one from the Ignition, or are they related. Could the bad spedo be causing all of this. The spedo only malfunctions in damp or wet weather.

Again Thanks for the help

Barry
