I don't have the correct adapter and gauge to accurately check the compression by removing the glow plugs (and those can be difficult to remove from a cold engine)

My method can be done using common tools. The fuel lines can be removed using a 14mm open ended wrench.

I then use a 13mm long socket and put it on the right side of the injector and move it side to side to loosen and then remove. I then clean the shafts with solvent and a lint free cloth. Clean the shafts of the injectors and place back.

Jack up right side of the car and remove the rear wheel. Using extensions and T18 socket you can turn the engine by hand.

You will need a second person to turn the engine or feel to see if the injectors push out when turning.

Relatively simple and can be done in about a half hour.

You will need new copper washers/fire seals from the dealer to reinstall. They are inexpensive.

This works for me.

If one of the cylinders lacks compression it won't start.

Good luck!

Here's my experience with no start. I did end up getting it fired up - post #67. I do have a diesel compression gauge that works on the little smart cars via the glow plugs that you're welcome to borrow if you're ever in the Edmonton area. Smart142's method is quick, and also requires minimal speciality tools. Give it a try 1st.

 

 

Good Luck!

newer injectors installed,got the glow plugs working (control box). Devised a compression tester cylinder one (270) cylinder two (0) cylinder three (90) psi thinking in going to have to go deeper and remove the head and check the valves. Any other ideas before I drop the engine?

I'm betting the valves will be the problem.

i like to put air into each cylinder while at top dead center and listen to exhaust and intake (and crankcase) to confirm diagnosis more before removal

 

if its a valve it should be very obvious

Copper washers can be rejuvenated by heating with torch if you can't get to dealership. It swells up the copper and compresses nicely as it is designed to

replaced Ebox???

 

If your referring to the ECU it needs to be matched with SAM and Odometer.

You can successfully anneal copper fire washers. Heat until red hot and quench in water.
