Does anyone know the exact location of the fuel pump relay? I know it is in the fuse box behind the passenger seat, however, do not know which number it is.

Position T on this fuse chart.

Which fuse chart?

Sorry, I did try to attach it but keeps telling me I have already attached it.
I even re named it and get the same result.

Thanks for the help TTtodd!

I am experiencing some major lag after a very hard drive last night. It ran perfectly with my newly installed BWK. Probably the best it has ever ran. The very next morning I've noticed major lag and hesitant to reach the RPM's it would reach very easily the night before. I have a 1 year old CM30 pump so I know that is not the issue. What may this be? I am thinking coil packs or fuel pump itself. Any insight?

Forgot to mention, I just replaced my CPS due to starting issues. This fixed the problem (never cranked over before). However, I am still experiencing starting issues on a first cold start at times.

please take this FWIW. I am in no way shape or form a professional tech.
Just a dude on the internet.

Read the codes. Without reading codes its just a shot in the dark.
Just because your pump is under a year old doesn't mean it is not faulty.
There is a code for too high of intake temp. P20E1 I think it is.

If you think its fuel, measure the fuel pump pressure to verify.

Read codes, test and verify suspicions. Thats what I would do.
