Done some reading on here for the past few evenings, but I want to clear up some questions I have before I proceed. I purchased one of the diesel compressor testors from Harbor Freight(mostly because it was cheap, on sale, and available when I went to Wichita today).The adaptors they have in the kit for Mercedes list models 190E 2.5L(1988-1989, E300 (1991-1999), and E320 CDI(2005). The older models have 12x1.25 thread listed by thier names, the newer one has 10x1.00 listed by it. I've never had the glowplugs out on this, although the po had just recently replaced them(they should come out easy). Do I use the adapters with the 12 x 1.25 thread? What do I unhook so as to keep the car from starting? I've read when some people are using the tester in the injector holes, they unhook the injector line(somewhere?). I think I also read where someone wired the stop button to close. I can push my stop button all the way against the stop, and the motor doesnt die. What do you suggest? I would like to do this here within the next hour or so, if you have any advice, please fill free to let it flow!
In the manual that came with this, it says to take out all the glow plugs, and install the testor in the first , FULLY depress the fuel pedal,and crank the engine for 8 revolutions. Record the reading on the tester. Release the pressure and move to next. I thought I read on here where you take two readings, one iniatially(I dont know how many engine revolutions?) then one later for maximum pressure. How does a person do that?
thanks,
Jim
