Engine now won't start 1999 ML430
I Started getting an engine light P0141 O2 sensor and I was delaying the work.
Then Went to P0161 O2 sensor bank 2 sen 2+ P0141 Bank 1 sensor 2
Ordered parts and then it started running rough and I got Codes P0301 Cly 1 misfire and P0305 Cly 5 misfire and P0300 random Cly Misfire
Ordered plugs.
After receiving parts, went to drive to a Lift at a friends company garage and the truck just will not start now..turns over easy, but just won't fire.
It has 177.000 on it.
Ideas? So frustrated now that it is stuck in the driveway.
Is it worth towing to a mechanic?
Appreciate any help

O2 sensor codes will not prevent you from start the truck.
But the misfire codes, together with the age of the truck indicates that you may have a Fuel Pump issue.
With a rubber mallet strike the fuel tank a few times and have someone try and start the truck. If it almost starts or does start, you need a fuel pump.

Thanks............it has been sitting a few days and now started, But it is still running rough.
Codes today are P0301, P0161 (pending) and P0141 ( pending)
At least it started.
The P0305 and P0300 codes have dropped off............but was only running 5 minutes.
I guess I have no choice but to get it to a local shop while it is running.......temp is dropping in NJ and getting tough to do much outside......my garage is full.
I am wondering if plugs would be a good choice to start along with both O2's........but don't want to run up an outrageous bill at this time
