220d hard starting

I have a '69 220d auto. It has over 330k on the od. I have little history on it but it still runs with some effort. When it's cold I have to pump the gas peddle as I crank over the engine and once it starts I have to keep the revs up for a few minutes until it goes into a rough idle. This car is far from being a nice ride but I got the car basically free. Any ideas on my problem? Thanks Courtland Also, how hard is it to convert to biodiesel and how easy is it to put a bigger diesel engine in it ? The 240d comes to mind. I also have trans. problems but I'll save that for another day.

My 300SD engine stalled yesterday and will not start

I got stranded on the road yesterday and had to have the car towed. At first I thought that I ran out of fuel because the symptoms were very similar. I added several gallons of diesel to the fuel tank to no avail. The engine barely started, then immediately after started running very rough and stalled. It would not start again. At home (after having the car towed there) I changed both fuel filters, disconnected the line at the fuel tank strainer and the fuel came gushing out, so no problem there. I used the hand primer pump to prime the system, tried to start the car - no luck.

300D fuel starvation

I'm having a fuel starvation problem on my '78 300D; it just isn't getting enough fuel when I push the accelerator pedal to the floor. I've been running it on WVO for the past 2 years. It has gotten progressively worse on power, and now it takes forever to get up to speed on flat ground and barely goes uphill at all. So far, I've replaced 3 injectors that were bad, had the valves adjusted, replaced the in tank fuel filter and cleaned the line from tank to front. I've also changed out the hand primer which was leaking air, but that didn't help either.

Will not power past 75 mph! Slight loss of power uphill.

Hello, I have a 1984 300sd with 230,000 miles. Did alot of work to it, thanks to Mercedes Source. Anyway, did valve adjustment, compression test (pressure max out close to 400). Changed injector nozzles to Bosios. Engine does not knock and is a bit smoother and responsive. Problem: pedal to the floor on highway and will not get past 75 mph?! Sometimes loss of power up hill. Have not changed the fuel lines from the tank. Is this the possible culprit? Thanks, RP.

honest diesel mechanic wanted Seattle

Hello, I am new to this forum, I have a 1993 MB diesel 350 straight six in my truck and would like contact information for a good mechanic here in the Seattle area. I want a mechanic that does not create problems, is very knowledgeable to all mercedes diesels, and does not mind working with and trouble shooting vehicles with SVO conversions. Evidently my truck is semi rare here in the states so said mechanic must be comfortable working on new things. My truck is a mid 90's G-wagen. Your referrences are appreciated. -Krashappy

Replace/Rebuild Inj Pump?

I've recently replaced the nozzles with your kit for my 300CD non turbo. The car ran great for two days, then it quit in a big way. I've replaced the filters,lift pump, bled the air out of the system and can now only get her started with the fast idle turned up. Lots of smoke, I mean LOTS of smoke and when the temp starts to come up and I turn the idle down she dies. She'll restart with the idle turned back up, and still all the smoke. I'm getting ready to pull the Injection Pump to have it gone through, or is there something that I'm missing?

Diesel starting problems - cont.

My daughter has her 1985 300D at school in upstate NY, I'm in Missouri. She can't get her car started. I changed the pre-glow relay just befor she drove to NY, for the first time, in March. The initial problem was that the glow light never went off, the relay fixed that. A couple of weeks after she got to school she mentioned that the glow light stayed on after she started the car. Ignition on, light on, light off, start car, light back on always. This is different than the original problem when the light never went off during the pre-glow phase.
