If the relay doesn't pull it may be the relay, or it is the MPFI control unit. It can also be oxides on contacts or even an almost completely corroded wire. what do you mean by if it pulls ????? im haveing fuel problems also. but mine is pump on or off depending on the mood of the car not the temp ????

so I know the problem is somewhere in the engine bay, not near the gas tank. Any suggestions? Fuel filter? ( I've been told that's in the gas tank so I don't think thats the problem.) there is a fuel filter under the hood. its about the size of a small coke can with an in and out tube on the top. its on the drivers side right behind the windshield washer filler cap. it has a flip lock to hold it in place and has 2 hoses going across the top and one going in and one going out. the 2 that cross the top are part of the venting system i think, just push them out of the way and you can pull the filter after disconnecting the fuel lines. caution!!!!! the fuel system is under presser, so some fuel will likely leak out, as well as the filter is full of fuel. so be ready for it.
