Update
 

I drove the car 3 times today and it behaved like a champ. No drama, no codes, no limp home messages. My money is on it all coming back soon however.

The way you described the random errors usually means alternator problems. Is Alternator original?

Finally got the body work done from the rear end (plus some extras)
- cracked bumper swapped out for a used/re-painted one
- new trim with old sensors (they survived the hit)
- lower rear passenger door
- hood
- trailer hitch blasted and redone

When the bumper was off, we noticed the two lower outer cavities had completely rotted out. He cut out the garbage and welded in new floors. The rusted out bottoms had the heat shields loose and flopping on the exhaust. All fixed now. She's not a garage queen, but for the mileage looks, sounds (x-pipe, 4.8 mufflers) and sits nice (lowered front/rear, hard race adjustable rear arms, spacers).

Also got the tires balanced. Heads in for a full detail June 10.

I think I had it replaced, but many years ago. That would make sense as these cars seem to be so picky when it comes to electricity, or the lack thereof. I wonder too if the fact that it was sitting for over a week without the battery connected could have played a role?

On another note, the gasket on the trunklid grip is a pain in the butt. The plastic inserts that the four screws go into strip if you look at them wrong, but the grip needs to be very tight for the gasket to make a good fit and keep water, etc. out.

I'm thinking of just shooting some liquid nails into the holes and then screwing the thing in after it dries.

Replaced leaking coolant reservoir, two coolant pipes, transmission coolant thermostat and oil pressure sensor. It's the second time replacing the reservoir and sensor - always leaking after 3 or so years :(.

What did you do to / for your E53 today??
 

Replaced fuel pump, also re-worked the sensor on left tank as I've been having a problem with the fuel tank never reading below 7.8L.

Fortunately being the grand wizard of e53 fuel supply, I knew right away when the dte stayed at 39 miles for 10-15 miles that I had a stuck float or equivalent.

Sure enough, get test six active and it showed less than 1.4 right and 7 or so left tank.

The left tank didn't drop over the next few miles or change from g forces. Implication; bad contact etc that is adding some resistances.

Full sweep outside car gave me proper readings and reset with test 21 so I don't need to run several tanks of gas to know if it worked.

When I tested the gas pressure after replacing the pump, the needle flutters, implication the o-ring is failing in the FPR.

I would love to test me theory that more than likely just the o-ring failed, but at 197k miles I'll prob replace filter and FPR

PS: yes @upallnight, it's the one I got from you. My friend from Racine drove it down to Chicago and I replaced on the street.

I had a weird problem installing; the center seat belt would not come out off its shell; I ended up having to cut the belt to move the seat enough to work.

Brought 1000# of floor tile from Racine to Chicago.

Quite happy that the fuel pump decided to quit AFTER i got to Chicago. Less happy it did while the tiles were still in the car not at client.

(But I needed to move them all toward the back before I could remove them anyhow). I already removed my tools the previous day so there was room behind the seat for all the 43 boxes of tiles.

This was with tools and tiles.

1000lbs! How’d she handle?

Day in the park.

I've been 600# (10%) heavy even then it does a fine job. Hills you can tell with the 3.0 and I can't take corners without braking.

The first thing I ever transported six years ago was 1300# of lannon stone (that may be a local term): flagstone used for walk. Did that within a week of owning.

With passengers, tools on the cargo rack and 600# of CMU (What old people call cinder block but haven't been since 1920 or so), I was at 6600# gross.

I typically have 600-700# of tools in my truck so an extra 300 is like two passengers.

It was a bit annoying the timing of fuel pump failure but i much much prefer an outright failure vs. intemittent crap.

I have my skinny set of tires on right now so it was the smoothest ride is had in a while, half a ton does a fine job of smoothing out the bumps.

That’s freaking awesome!!
