Re: Help with fuel system. Pump not running
Sounds like the FP relay is not being activated by the ECM,...do you see the check engine light indicator turning on? Your problem could be caused by a bad EEC relay, which is located above the ECM behind the right kick panel. Since the car has been in storage for a long period of time, it is also possible that the problem is simply a bad ECM ground cable or connection. Check the small ground cable by the (-) terminal of the battery and make sure it's clean and making a good connection. Hope this helps.
