I have checked fuel pump relay. It had trouble starting a few times, after applying gas pedal at start up that got it started, now nothing. No whirrr from fuel pump. Check engine light has been on for a few weeks before start issue, scan test showed o2 sensor or cat convertor issue. Is it the fuel pump or possibly something else?

If fuel pump is not coming on and relay is tested OK then check fuse to fuel pump as well as wiring at the pump. How many miles is on the vehicle? Most likely the catalytic converter is not at fault here nor is the oxygen sensors. Does everything else work when turning key in ignition (i.E. Radio, lights etc.)?

Here is the fuel pump relay (e14) location in the diagrams below. Check out the diagrams (Below). Please let us know what you find. We are interested to see what it is.
