Hard to start and erratic idle....

So I just bought a 90 240 about a month ago. Ran great then one morning was really hard to start and idles really erratic. Sometimes wont really start. Has a code 1-4-4 Load signal missing to control module.... Any ideas on common problems and things to check that would cause this code to pop up with these symptoms.

check/replace fuel pump relay, and make sure connections to theECU andICU are ok.
