Scion xA 2006, 152,000 miles.

I started throwing a code P0302, then P0300. Car was running a little rough. I replaced the ignition coils: fault still showing.

Replaced the spark plugs: fault still showing. Still riding rough.

I put an engine cleaner in the tank. Car continues to ride rough, then car lost power in second gear going up a hill.

I parked it for a week and replaced the fuel injectors: fault still showing. Having difficult starting and moving now.

Next step, I'm thinking of replacing the fuel pump. Does this seem like the next logical step? More sound near the back of the car than there normally is. Anything else I should be checking?

Thanks!

First, be sure all your vacuum hoses are connected, I left the one on the air cleaner housing off once and caused a check engine light. Then after that yeah I would say the fuel pump is going out. I beleive you take out the rear seat cushion to get at the access hatch. Be sure to disconnect battery before messing with that though. I dont know if there is a fitting for a fuel pressure gauge to test the pressure.
