2004 E320 has run great since purchase with 95K miles, but now at 175K it has faltered a few times on start up and now will not run. It was trying with the start valve shooting fuel and then died but the battery was low so I replaced with an AGM, and no more low voltage!
Now there is no firing at all so Im checking for pressure at the fuel rail. The fuel pumps arent on fuses are they? And maybe some other FP issues like the filters or hoses?
I was doing some jump starting and charged my off-grid batteries when the system got low with jumper cables, and it brought the voltage right up but hopefully no damage to electronics. At one point I did have a very high draw from the Positive post..due to connecting to a dead lithium which pulled high amperage. OK off to check for fuel pressure and to listen for the fp hum in the tanks..(after checking out some video advice on you-tube)
Thanks in advance for any wise counsel.
