Hi, bleeding the air from the diesel injection pump can be very difficult on this model. The best way to handle this is to start the car using a starting spray such as WD40 or silicone. Have a helper crank the motor while you spray into the air intake. You need to run the motor on the spray until the air bleeds from the pump and runs on it's own. I usually hold the throttle open and run the motor on the spray at about 2000 rpm while bleeding the air from the system. If the car has a manual transmission you can tow start the car.
Let me know if you have any questions.
Hi Mark, I found that spray silicone works best. Go ahead and glow it and see if it attempts to fire. I would not use ether. Also make sure that you are getting voltage to all of the glow plugs. Are the bus bars between the plugs getting hot when you glow it?
I always leave the nuts loose on the injectors when using the silicone spray and then I close the nuts as soon as I see fuel oozing out.
It sounds like there may not be enough compression. You should probably do a valve adjustment and run a compression test. Are you spraying a steady spray of silicone into the intake while your helper cranks the motor?
Let me know what you find out. The diesel is all about the compression. If you have compression and glow plugs you should be able to run it on silicone spray. If it won't even fire I'd have to suspect it has lost compression. You might try removing the injectors and squirting about 6-8 squirts of oil into each hole and letting it sit overnight then try it again.
I'm not sure about the compression testers. You will just have to check the adapters and see if they will thread in. I would not try spraying the STP into the motor. The buss bars will not get hot if the glow plugs are bad.
