Loren
I sent your message to the Owner of AGCO Automotive he replied back with
this.
Have them verify fuel pressure and volume. It is NOT enough to have
pressure. It must have the correct pressure and full volume.
Hope this helps.

Re: [MBZ] OT request for help
Since it does not appear to be a compression issue, I would look at the
coil, distributor, timing chain, cam sensor or equivalent (adjustment for
wear in the timing chain?), or something already changed that was defective
or not the correct part. Perhaps put a scope on the ignition and see if it
is trying to fire properly.

Coil.

Has the fuel filter been replaced? Sounds like possibly a low fuel
