So the jumper is the solution. LnL Sounds like an improvement that does not work so well to me. I like my Diesels.

But my limited experience suggests that the pressure switch (or timer?) will turn the pump off with air still in the line. So to pump all the air out requires a lot more time than the pump cycle when the key is turned on. --Philip ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
Re: [MBZ] 1999 e320 still won't start
Finally, it's alive! What I did after finding out that I had power at the fuel pump relay and that jumpering the relay socket did not get me any fuel pressure under the hood: I bought a used e320 fuel pump on eBay. When it got here last week, I crawled under to RR it and found the old pump has screw terminals while the new pump takes a plug in connector. At least I did prove the pump bad, because I was getting 10.8V at the pump terminals during cranking but the pump wasn't running. So I ordered one with screw terminals from another eBay seller last Thursday. Monday night I got an email from Paypal saying my money was refunded on the 2nd pump. No other contact from the seller. After giving it some thought, I soldered two wires into the connector on the new pump, then filled the socket with RTV silicone. Today after the silicone was hard, I swapped pumps. Lost about an ounce of gas after clamping the hose from the tank to the pump with needle nose vise grips. (My pump is just in front of the gas tank, not by the filter) Cranked it over 4 cycles without even a sputter. Darn, I was totally sure it was the pump, especially after testing for power at the pump itself. Then I got an assistant to crank it while I held onto the pump. The pump was indeed running, and the engine sputtered a bit. Crawled out from under the car, cranked it over, and it immediately settled into a smooth idle. It just took 5 start attempts to get the system primed again. Now I've got to prime it all over again when I replace the filter (which cost me more than the used pump, BTW).

Not sure on that model, but the 60 to 87 gassers, it is near the RR axle. Take a couple of long wires to run jumper to the battery.

Re: [MBZ] 1999 e320 still won't start
I found this which seems to pertain. I have voltage at one terminal of the fuel pump relay under the back seat with ignition off and voltage at another with ignition on. I have 0.6V from ground to the relay terminal that's switched by the relay, seems like it should be 0.0V. Can't hear pump over traffic noise when I jumper across the pump relay terminals, and don't have pressure to the fuel rail after I jump the relay. I'm concluding that I've got an open circuit in the pump wiring or the pump itself, or the pump isn't getting good ground. Doesn't seem to be much more to do here in the hospital parking lot. ___ http://www.okiebenz.com For new and used parts go to www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Big Blue is sitting on my Landgrebe dolly in my driveway, with a battery charger on an extension cord. I like that dolly better than a Demco Kar Kaddy. Tows like a dream, at least at 30mph. It's nice not to have to wonder if the dolly fenders will steer into the car's fenders when you turn around in a parking lot. (Demco has steerable fenders, Landgrebe's are fixed) Will crawl under the car tomorrow to confirm my fuel pump diagnosis. Then need to get in touch with Q Jr to see if a Pierberg is really worth as much as bimby.biz says it is. I guess it could be worse, Advance Auto wants $560 for a Bosch 67968. I often get stuff at AA when I have a 40% coupon code, but I really don't want to pay 60% of AA's price. CrockAuto lists two Boschs for my car, they want twice as much for the other one as they want for the 67968.

Mitch, Sorry I didn't recognize the original post as your initials. I think that is a good choice. I bought a used fuel pump for the 380 and it turned out ok for at least 5 yrs. ...so far, so good. Good luck! I hope that solves the problem. I hope you get a break in the weather to change it. I would guess it is pretty much the same and same place as 123,124 and 126 cars. Kaleb C.

It feels good to have the car in my driveway after leaving it there overnight. First time I ever used my dolly. I never got around to putting brakes or a winch on it (or even fixing the lights, as I intended to fully rewire it when I got brakes). Fortunately I had a come-along handy, and was towing a MBZ with my dad's pickup instead of towing a MBZ with a MBZ. Absolutely have to put brakes on the dolly before using the wagon to tow anything.
