Duster Roars but wont start...help !

trevorcrum said

Sorry, the parts are Summit RTR 850028 Distributer, and MSD Blaster 2 - 8203 coil. I wasn't sure that I hooked it up correctly, but it has been running for the past month or two with no problems so I claimed victory. Perhaps a little early. I have left the other ignition wires in place for the most part, as I'm again going to swap out the harness shortly. The directions on the RTR were good enough to hook it up, but they didn't help much with the tear down of the old stuff....orange box, and ballast wires.

I know it sounds like I don't know what I'm doing partly because I don't but the old distributer was crap, and the new one was a relatively easy install.

"Red lead to switched 12v (coil positive)
Orange lead to coil negative
–
NOTE: You must use a coil
with a .7ohms primary or LESS.
Black lead to engine ground"

I would start by checking for voltage in both "start" and "run" positions of the key

Get to the point where the distributor red wire connects, clip your meter there. Turn the key to "run" and check voltage which should be within a couple of tenths of a volt "same as" battery voltage.

Crank the engine USING THE KEY and take a second reading while cranking. Meter should again be close to "same as battery" whatever that might be during crank, and should be at least 10V or higher
