This is my first post here, so thank you in advance for any help. I have a an '80-242 as stated above with the CIS system 4spd manual with elec. O/D. The car will start but run and idle poorly unless it is revved up considerably. It has always started hard but does not clear up once warm like it used to. I did a little imaginative engineering to the fuel pump relay... and substituted a 40 amp headlight relay. I figured out which wires make the high pressure pump run not sure what 3 blue wires do but the engine ran similarly to above unless power was supplied to them. I replaced cap & rotor as well as plugs but did not get a chance to check the wires as I was racing the sun. I have removed the strainer from the in-tank pump and replaced the little rubber hose that connects pump to fuel outlet pipe. The car was running only off the high pressure pump for short while due to the above problem and now makes a whining noise but has operated OK for last 10K miles. I am not interested in making the car perfect as far as the initial start problems are concerned; just making it drivable.
