Re: [diesel_mercedes] Hand Primer Pumps

 

Yes, I agree, about sitting. But this car drove great last fall, parked it when it got cold, started it the other day when it ran for 10 seconds. I never used the pump till after it stopped, so if that's the problem it sucked air screwed in.  Car runs super good, maybe the best running car I've ever had, but I hardly even drive it. Last year I just started a new program(cant believe I did not think of this before), up here in the north country we get seasons and basically you live around the seasons. We have a short season of air conditioning. In my240 4-spd I have got the air to work pretty good but don't need it till around July tru September.  In the 240 auto no air, I tried, but its such a hassle keeping one air condition system working in these cars. So last year I starting driving the auto till I need the air. But I cant start driving it till Subaru season is over, which lasts tru March and mud season and break up. We must have about 10 seasons here. The auto is fun to drive, faster, and the trans almost shifts like a manual anyway without a clutch. Also has a sunroof. I can drive the 240's till about late October when it gets cold and then starts snowing, that's when Subie season starts. I might need chains on my 240 to get out tomorrow, hope not. Max

That's what happened to me ~ I think it was one of my NA red Diesel Coupes , it began to run poorly then roughly , I was trying everything and finally a member here told me to try replacing the (then $10) primer pump ~ I did so and the car <magically> ran perfectly again .

I have seen two of the manual pumps that leaked cause a problem.
When they leak fuel when hand pumping, they can allow air to be sucked
in when running. Both that I saw (on dally driven cars)showed up as severe loss of power on hard acceleration. Yours, after sitting may have had enough fuel in the IP to start and run until the air got to the output, then no pressure. That is a cheap and easy fix.
On a side note, I think the hardest thing these old machines is to let then sit.
Of coarse like others here I have a few of these car and can't drive them all.
