Last night I parked my 85 300SD with no problems. When I went to start it this morning i didnt crank it long enough and she started but died shortly there after. Since then I have not been able to get her started. I primed the pump and I could feel fuel rushing through the pump. I recently replaced all of the glow plugs with bocsh. She has high cranking rpm and a charged battery. I replaced the starter two months ago with a bosch rebuild. I was having problems with this before the starter went out and after replaceing it I thought that I had fixed the problem. Acording to mercedes dealership the trap oxidizer was replaced in 97 with 100,000 less miles on it then she does today. What are symptoms of a clogged trap cat? She idles realy good and up until yesterday had power accelerating. If it wern't for the fact that she idles good, i would check the valves but I have no reason to suspect that. After the trap cat is replaced has anyone ever heard of them clogging up again? When I crank her she puffs out a thick "dry" soot. I also do alot of town driving...barley enough time for the car to warm up...but I have only put a thousand or so miles on her since I got it.
