Followed advice of using a jumper from battery. Seemed to help a little. So I then installed a Ford type starter solenoid from the battery to the glow plugs using two 10 gage wires, one to the front glow plug & one to the rear. At first, after a couple tries, it started right up. Warmed the engine up & turned it off & tried to start it with no success. Acting the same as always. Rebuilt IP, new glow plugs, checked injectors which seemed OK, new filters. When I first bought  the Quantum it would always start but overheated, had head redone, valves done. Then started right up but the IP leaked. I did not replace the injector washers with new ones. Have gone thru the timming sequence several times. New battery with battery kept at full charge with a battery tender. Starter turns engine over fast. Fuel seems to flow thru IP OK. Once it starts it runs fine. If I coast down a small hill, it will start.
Re timming, I bought a rather expensive dial gage that is calibrated in metric. I am wondering if I am using the gage right? I will set the flywheel at TDC, loosen the cam gear & tension pulley, lock the rear of the cam & the IP per Bentley. Then tighten  the tension pulley & then the cam gear. I will then rotate the engine contra clock wise, per Bentley. Then I will insert the dial gage in the back of the IP. Then  I will rotate the engine clockwise until the gage makes one complete circle & then lock the IP in place & I find the flywheel shows TDC. I have tried moving the IP a little bit clockwise & contra-clockwise but no change in balky starting, only a change in diesel knock as I move the IP slightly contra-clockwise.. Am I doing something wrong? I want to fix this Quantum myself. I don't know anyone locally who knows more about VW diesels than me but if one more attempt at re-timming doesn't work I will have to start looking for someone
