Re: [MBZ] 300D 2.5 Turbo injector nailing?
It can take some time to get the air out of the lines, and you will get injector knock (which is really late opening of the nozzle) until it's all gone, but it shouldn't take very long. There are two seals on the delivery valves -- the copper washer at the bottom and a rubber o-ring at the top that seals the fuel reservoir. That is what was leaking on yours, but to replace it you must remove the delivery valves, and hence must then replace the copper seal. It's difficult to get the copper seal exactly sealed, I've done a few and had to repeat a couple. If it leaks, there is no residual pressure in the line to the injector, and the fuel will be injected late as the nozzle will not "pop" until it's at 1500 psi or so. Very far down the power stroke and it goes "bang" instead of burning cleanly. You can check by cracking the lines at the injectors one at a time while it's idling. If the noise goes away when you crack the injector line loose, that pressure valve copper seal is leaking, and the copper seal probably needs to be replaced. They are NOT very tight, I seem to remember the tightening sequence being 25 ft/lbs, 25 ft/lbs again without loosening, then 30 ft/lbs after a few minutes settling time, again without loosening. Use a good torque wrench, going by feel will usually result in scoring the copper washer and it leaks, or distorting the fuel pressure chamber and getting a leak. -Original Message- From: Mercedes Discussion List Sent: Jun 27, 2024 11:41 AM To: Mercedes Discussion List Cc: Curt Raymond Subject: Re: [MBZ] 300D 2.5 Turbo injector nailing?

Leaking delivery valve seal. I wouldn't change those unless you have a fuel leak from a bad o-ring or injector knock at idle, they are a real pain.

Re: [MBZ] 300D 2.5 Turbo ABS light rough idle
They are easy to bench-test using a standard current-limited lab power supply. Set the current limit to less than the fuse value, and start raising the voltage. At the trip point it'll short out and the voltage will drop to zero.

Re: [MBZ] 300D 2.5 Turbo ABS light rough idle
These are a classic crowbar overvoltage protector. The voltage, if over a threshold, triggers a big-ass SCR that shorts out the power, thus blowing the fuse and protecting all the presumably-sensitive downstream circuitry. -- Jim ___ http://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] 300D 2.5 Turbo ABS light rough idle
Who knows. Odo still not working. I’m guessing 400K though. BTW, 3 weeks ago after hitting a pothole a bunch of times - same one (shit state of Massachusetts) I hear a bad noise when turning into driveway, and front wheel collapses into wheel well. Lower ball joint sheared off! Just got it back from shop today.

CHANGE your FUSES. Kidding aside, with the variety of affected systems, sounds to me like it could be a general low voltage symptom.

That sounds like the classic small air leak in the fuel system, letting it drain while sitting. It will run fine as long as it runs every day, and you will not likely see fuel dripping.

Re: [MBZ] 300D 2.5 Turbo no start
Dimitri, Dwight. FWIW. If the lever is down the rack is in the shutoff position and will not supply fuel at all. The vacuum shut-off device could be stuck, maybe? (I have a spare). The pump side plate, when removed, will let you access the rack. I have an OM602 injection pump with 90k mi. that you may have. Confused yet? Fred p.s.

Re: [MBZ] 300D 2.5 Glow Plug Relay
Ok so one is indeed the ground. How do I check to see if ground is working. Kaleb said to jumper it to another known ground but how do I do that when the connector connects everything together? Jumper every contact in the connector with every corresponding pin on the relay? That is technically challenging to do.

Re: [MBZ] 300D 2.5 Glow Plug Relay
Thank you Fred. This is very helpful. I tested all the glow plugs at the glow relay connector and they all check out. I’m not sure how to test the system leaving one or another pin disconnected since the connector connects them all together. Would I have to rig jumpers between each connector hole and its corresponding pin?

Re: [MBZ] 300D 2.5 Glow Plug Relay
Dimitri. FWIW found this. I'm not familiar with that glow relay part number but I'll assume the connectors are compatible with MB passenger car harnesses and it's an afterglow relay. Forget the wire colors and check for pin numbers either on the relay itself or on the connector. The numbers should correspond between relay and connector pins. Here's the pin list for a 90-91 300D 2.5: pin 1 = +12V when key switch in run to initiate preglow cycle (W124 = hot side of fuse 7) pin 2 = +12V when key switch in start to terminate preglow cycle (W124 = NSS) pin 3 = +12V to gauge cluster glow indicator pin 4 = ground pin 5 = blank pin 6 = signal from glow temp sensor by water pump to determine preglow and afterglow cycle times Assuming each glow plugs test between 0.7- and 1 ohm at the glow relay connector, leave pin 2 disconnected then see if you get the max preglow cycle of ~30 seconds. I don't know how the glow relay behaves when there is no temp sensor. If this gets to be too much work, a 617 pencil type glow relay should work for you since afterglow isn't much of a benefit in the tropics if you have healthy glow plugs.

The first two are Duh!, but they all need to be working correctly, or you don't get a good start. IIRC there was an ignition-on signal, a start signal, and a dash lamp signal. Ignition-on started the GP timer, start-release stopped the glow plugs, and the light was the light. Not sure exactly what your car has. Check the car schematic. -- Jim ___ http://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] 300D 2.5 Glow Plug Relay
Get a wire and connect one end to the power coming into the relay then stick the other end on each pin in succession and see if you get power/heat to that particular plug. If the plugs get power you’ll know the problem is with the relay. If the plugs don’t heat up then there is some other issue. —FT Sent from my iPad > On May 13, 2023, at 8:57 AM, Dimitri Seretakis wrote: > > How do I jumper around the relay?

Check for broken solder in the pins and wires in the connector. It’s possible the keyswitch is bad too, although unlikely. Have someone operate the key switch while you listen for the relay to close.

Re: [MBZ] 300D 2.5 Glow Plug Relay
I went to Ace hardware and got a test lamp. The relay has power. I then tested a singular glow plug and it had no power so I proceeded to inspect the harness from the relay to the plugs and found that it was chafed and had visible conductor material. If the wire to one or even some of the plugs was affected then there would still be some glowing action but there is none. The glow plug light would do some thing like not turn on and then once the car starts, turn on for so many seconds. Therefore I suspect that the ground wire is shorted. Is it worth it to try to repair the harness? Should I try to find a new harness?
