Re: died while driving
While engine is running grab the wire harness that leads into the distributor housing with a pair of needle nose pliers and wiggle the wires!!
if the engine stumbles or stalls that is your prob!!!
go to parts store and get a magnetic pickup assembly!!
i think they call it something else but its the same concept, just different because it's a dodge thing!!!

no spark from coil directly?
is the cam turning, is the dizzy rotor spinning. ????
check all fuses first. Ig-coil, FI and dome.
then using diagnostic jumper wire or fuse, (as approp)
crank engine look for code 41 o 42.!!!
USA cars , answers only
our cars are all EFI that year.
no engine swaps to Suzuki G16A/B sidekick or tracker engines.!
1: engine cranks
2: no spark
3: The ECu makes spark
the CMP sensor in the DIzzy , (never fails if rotor turns, does rotor turn, if not cam belt igored and now snapped.)
the cam turns. the CMP fires. the ECU takes this CMP signal
and fires the ignitor next to coil and the coil charges, and release and BAM spark.
that is it.
the ECU will tell you when the CMP dies or the Ignitor fails
why not ask it.
1: key on
2: diagnostic jumper in place (flashes 12s for ok)
3: crank engine,for 5sec, not 1 ,not 2.
3: release key not off.
4: see code 41, or 42, BINGO !@!!!!
if its got no fire and you changed your cam and crank sensor try replacing the ignition Coil then if it doesn't work replace the distributor cap and spark plugs and wires if that doesn't work then take the distributor cap off and replace the distributor Rotor if it still doesn't work replace the wires to the rotor if still i dosent work check your fuses but i assure you that should fix it.
1979 ford 400 Drove inot shop did a cam shaft change and put all back together and no spark! put new coil , distributor, eletronic brian , wires ,rotor, cap, and check wire harness for brroken wires . still no spark? ANY IDEAS??
check the wiring harness at the coil,sometimes that plug will get loose or dirty resulting in a no spark.
The only ign system parts are the crank sensor,cam sensor,dist,dist cap,rotor,spark plugs,wires,and coil,and the ecm which controls all of these,is there a check engine light on?
run a scan tool to check for stored codes or system events stored in the ecm.
