Dynasty 1989 3.0liter : not hear fuel pump turn on, trouble codes
Csr started to lose power while cruising highway . Turned off, would not re-
start for one hour. Then , all AOK drove 10 miles home . Let sit one week.
Just trued to start. Engine cranked, not fired up. I listened for the usual
sound of electric fuel pump when I turn to ON . Not hear electric fuel pump .
I did hear what sounded to be a relay in engine ( driver wheel engine bay
Pulled engine codes visually :
code 1 2 = ?
code 2 2 = Coolant temp sensor Hi /low
code 4 2 = Auto shut down relay ( why ?)
code 2 2 = Coolant temp sensor hi/ Lo ( again !!!)
code 3 5 = Radiator fan control relay circuit Open /shorted
code 5 5 = Done ( I believe )
More info : ASD relay passed bench test . Is fuel pump the only suspect or is there more ? Can I check the 2 leads that the ASD relay feeds to see if there is continuity in the circuit (I am guessing that the 2 leads are the power supply and the return from electric fuel pump?? Do not know for certain). My initial continuity of these 2 leads showed open circuit . I fear bad fuel pump. Can anyone confirm / deny? I read that I can do a direct feed of battery 12v to fuel pump to check for sound of pump working. Did not do that yet.
Update : car sat 6 hours, I turned key to Acc position and heard fuel pump start pumping . It started immediately when I moved key to ignition . Based upon my experience, I feel that I have a faulty connection somewhere from after the ASD Relay. I would like to put my hands on the ground connection. I am told that it is " in the rear quarter panel ". Can someone send exact details / photo. I do not have a lift. Vehicle is in the street , so I do not have the luxury of raising it and doing a thorough search . Hope it is easy access from the curb parking position.
