1996 Mercedes S500
About to give up, help!

Hello,
New member here.
I have a 1996 S500 that has stumped everyone. Started a couple months ago, cranking but not turning over. Took to a local mechanic, a new fuel pump and filter was put in. He insisted he was not getting a reading from the pump. He had it almost 2 weeks and pretty much gave up. I had it moved to another mechanic that claimed to know more about Mercedes. They changed out the crankshaft sensor and I had it back for 2 days. Then it started with the same issue. Went back to that place and they ordered another sensor directly from Mercedes and installed it. I had it back for one day then it started turning off while driving. I sent it to the dealer to see what they thought. After being put on their computer I was given a long list of possible issues.
Fault on cam sensor bank 1, misfire cyl 1, can signal fault, fuel pressure reads 60psi and holds no rest pressure, found fouled out spark plugs. Suggested repair was to install new plugs and clean out fuel from cylinders, but did not feel confidant this would solve the problem. Anyone have any suggestions or ideas? I am not sure if I should even pursue repair? Thank you in advance for your time.

This is the real story!

Epiphany was to see if anyone had other suggestions from previous experience. I thought this was what this forum was about? No, the quote was not more than the car is worth. The issue was that the dealer did not feel like this would resolve the problem.
As for crappy shops, well both were AAA approved with high recommendations. As most people experience, shops say they can do things they can not. They take advantage when they can. Yes I spent money on parts that weren't required and yes I was without a car for almost 4 weeks. So shame on me? Thanks for your help, douche!

You just met our resident scold.

Change the spark plugs, put a fuel pressure gauge on your fuel rail, find someone on this list in your area with a diagnostic system, log all current codes, research causes of those codes, repair/replace the most likely culprits, clear all current/stored codes, drive car.

If engine light comes on or another problem occurs, read codes, research/repair/replace the next most likely problem item, clear codes, lather, rinse, repeat. Not all problems will throw a code so that adds to the fun factor.

A CAN signal fault can occur just because one of the data lines was unplugged momentarily while the battery was connected. If it is a "current" code, you need to deal with it. If it is "stored", it just tells you an error occurred sometime in the past. My '99 had not been to a dealer in over a decade and the list of stored codes was intimidating on first look.

Is there another way in the trunk if the key/lock isn't working and the battery is dead?

I didn't try to hijack anything. I asked because most threads in the W140 are dead and I thought there might be someone here with a more technical slant, but thanks for wasting everyone's time.
