diesel injection pump issue
99 E300 TD 152000
Had leaking delivery valves, so I replaced the O-rings and crush washers. Everything worked great, but it sounded like it was clacking a little more than before. I drove it over 1000 miles - no problems.
I decided to have another look at the valves while doing in oil change, etc. just to make sure the springs were aligned good & the washers weren't stuck in the delivery valve.
Everything looked fine, but this time when I put it all back together, I had an engine miss.
I traced it down to the delivery valve closest to the front bumper. There is no fuel coming out of it.
When I loosen the delivery valve - plenty of fuel shoots out, but when I tighten it back up (35nm)....nothing comes out. I tried this several times and get the same result. I checked all other delivery valves and they all work fine. PLEASE HELP!!! Thanks - Tim
