[QUOTE="Fishfiles, post: 34341, member: 782"] Yes spin the motor over with the starter , after you crank open all the ferraled tubing nuts on top of the injectors and have someone else spin it over so you can see the fuel coming out , you can hook up a starter remote switch or even use a screwdriver at the starter solinod but thats primative and can screw up the threads on the stud on the solinoid from aching , let the fuel flow for about 30 seconds out the injectors then close them it should fire up , if not do it again , I will close one at a time as it is spinning and by 3 closed it is usually running ----------the compression is easier tested thru the glow plug holes , if not adaptor is available and you have an old glow plug you can make one if you can weld a fitting to the top of an old glow plug which you cut with a saw or grinder then drive the guts out of it with a punch while in a vise , the compression should be like 450- 475 , and all within 10% of one another , I have learned to feel it with my finger pretty good and can see a problem alot of time without a gauge hooked up , as if one cyclinder wouldn't even pop your finger and others will blow it off [/QUOTE]
