One final question on this hard starting issue. As I mentioned, I completely cleaned the ground strap connections, which were dirty, and suspect that will clear up the issue. My question is, the original strap is in one piece, not frayed, but does look old. Can age alone increase the resistance on an intact braided wire? If so, anyone know where I can get a new one?

Disable the ignition (pull power wire to the coil) so the engine just cranks and cranks w/o starting. Have someone crank the engine while you measure voltage from the engine case to a chassis grounding point. If you get appreciable voltage like over 0.5V, then change the strap. I replaced mine with a 4-gauge strap from my flaps. They have many lengths available. |

(IMG:style_emoticons/default/agree.gif) My car never had one as the trans was out and the car a roller. Made one from a piece of new small diameter welder cable and got a local shop to crimp the eyelets on and all sealed with heat shrink. Have a second one made up but yet to fit . |
