A: Take your battery jumper cables and go from the ignition box (yes, grip it onto the box) to the distributor housing. If that doesn't work, then the breaker plate ground wire is broken inside the dist. Moving the dist around can make it engage and then not engage (kind of like the filiament in a light bulb when you shake it around after it "burned out" sometimes) From: Marty Bricker <mbrickerusn@xxxxxxxxx> Subject: Spirit engine problem fixed....now the %&*^$ SX/4 To: AMC List <mail@xxxxxxxxxxxx>, northtexasamc@xxxxxxxxxxxxxxx OK, latest update...it is electrical and not fuel. Checked spark from the coil and the plugs and it was weak and then non-existant. Pulled out the TSM and did some T/S w fol results: -ign coil primary circuit checks out ok -coil checks out ok -per TSM removed coil wire from distrib and disconnected 4 wire connecter from ign control unit(icu)...no spark as it said there should be... -connected ohm meter btw D1 from icu and batt neg and had 2.6 ohm reading which TSM says is bad ground (less than .002 is acceptable). -I traced the D1 wire in the wire diagram and it goes to the B1 connector from the distrib (this is the ground wire) -checked B1 to batt neg and it read 2.6 ohms indicating a bad ground of the distrib -removed the distrib and checked the area around the distrib hole and the distrib hold down and it showed good ground -With distrib out of car rechecked continuity of B1 ground and it was good! -reinstalled distrib and checked continuity numerous times and it showed good -attempted to start car and it fired right up -let car warm up to reset timing, had timing reset and dropped idle back to curb and car stalled...wouldn't restart...same indications as original -disconnected distrib connector and checked B1 and it showed 2.6 ohms again indicating a bad ground! It appears that engine heat is somehow causing the ground to fail in the distrib. Is this possible/probable? The distrib is a new/rebuilt unit that has a lifetime warranty so I can take it back. Just wondering if I'm wasting time doing this. Is there another way to ground the distrib to check out the theory? Thanks. Marty
