360 Engine cranks but won't start

Yup. You have a Mopar breakerless conversion. Stuff to do

1........The orange box MUST be grounded. MUST. Remove, scrape around the bolt holes on the firewall and back of the box, and remount "tight" using star lock washers

2.......The rubber distributor connector is a very very low signal. This connector is subject to corrosion. Remove that connector and 'work' it in and out several times to "scrub" the terminals.

Remove the cap, inspect cap and rotor for dirt, water, wear, carbon tracking. Inspect the pickup coil and reluctor for damage and rust / debri. Pickup is magnetic, so it can pick up bits of rust

3....Remove ballast resistor connector and ECU connector and work them in / out several times.

4....Later when you get the chance, put on your list. Buy a .008" (inches not metric) BRASS (nonmagnetic) feeler gauge, O'Reallys used to have them in a small set. You use this to check the reluctor to pickup coil gap, which adjusts just like points used to

5...Clip your voltmeter to the coil + and turn the key to run. You should see somewhere around 5--8 volts plus or minus.

With key in run, check coil NEG. It should be very low voltage, lower the better, perhaps 1/2 a volt

6....With the meter back on coil + crank the engine using the key. Voltage should be "same as battery," and not less than 10.5 volts, absolute min. 10V Higher the better.
