you may try adding a engine oil flush follow the instructions on the container if the lifter is blocked that may help but that engine at that model/year suffered with worn nicosyl coated liners which made the engine poor starting/noisy unless it has been reworked with cast liners

Is it the PSI specs good {30PSI?} If not u have to start w checking 4 vacuum leaks, oxygen sensors, get emissions test to get all other emissions read (HC, NOX, CO) All the readings will give the tech a path. U have to have the right amt of fuel going into the pump & regulator to get the right PSI too. Clogged exhaust? The possibilities go on. Good Luck

the electronic part of the unit ie. module is seperate from the pump unit and can be interchanged someone may have put a module from a different unit on to your pump motor unit ie, from a xkr which as a differant connector

Could at either plug(corrosion) Most wires break close to the plug, Check voltage a couple inches back. Unplug it(if you haven't already) check it. If you have voltage at the brake switch and a couple inches back(probe the wire) nothing at the Shifter solenoid. I would run a new wire to it. Way easier than removing the console and dash to find the short. If you have other problem, I would be looking at the fuse panel .

Possible bad wire in motor so it opens up and stops motor after heating.

Welcome to Fixya

The car might be stucked in Valet mode. Use the black key that you have to open the trunk, it overrides the Valet Mode. The key goes in a hole that is between the X and the K on the emblem on the rear of the car.

I strongly recommend a repair manual if you DIY. Auto parts store may cary or try filepeep.com or manualslib.com

You've done most of the steps I would have so far... Now use a meter and trace the wires backward. Sounds like a broken or chewed up wire along the route backwards. Also try a separate wire with power to see if you can deliver power to those lights. If they work, albeit temporary for the test, you grounds are good. If one works and the other does not, then THAT ONE has a ground loss. In any case, you have it narrowed down, and I would hope that by now you may have your answer. Let us know so we can share our knowledge with other readers. Thank you!

Driving Range or Distance you can go at average mileage and amount of fuel in the gas tank. One of the items that will display if you poke one of the buttons to the right of the top of the speedometer.

Un hook battery and let sit for 30 minutes with no power. This should let the capacitors bleed down and reset the code. It probably has a lost power code that is being retained memory. I’m happy to help further over the phone at https://www.6ya.com/expert/david_c087e4b7d13c0163
