After getting off the interstate run it seemed to lose pressure at the gas pedal. I had put gas in it though it was showing I had some. Still low pressure fuel getting home. In park it runs perfectly fine and quiet. I had noticed a slight scent of fuel after filling up at station.

No codes and a tight fuel cap.
What should I look at 1st, fuel pressure? Plugs? Compression? And where is the hose to T off of or to connect gauge to? And what psi should it be? Anything with MAF or other sensors to look at?
Last year a new fuel pump was put in.
Thanks
I will be reading the 02 fuel ratio and checking pressure, but where do I T in at for pressure reading and what's the procedure/PSI?

The fact that you replaced the fuel pump a year ago could be the problem, has it a name brand or OEM pump? If not, then this is where I would look first. Here is how to check the fuel pressure and what the PSI should be.

Fuel pressure. 281 to 287 kPa (2.87 to 2.93 kgf/sq. Cm, 40.8 to 41.7 psi)

You can rent a fuel pressure gauge set from the auto parts store for free in most cases. Check out the images (below). Let us know how it goes.

Thanks.I cleaned up the plugs, ran seafoam in tank and secured all air lines an cleaned up throttle a tad. Now no problem. Maybe something in the line. Fuel cap maybe, not sure. But it's running better now.
.I'll keep this for later if I need to look at fuel pressure.
