1 of 2 tries on this. either u'r not getting a proper ground and u need to make sure that u sand where the module sits at the firewall. both the wall and the module need to have bare metal touching each other.
oorrrrr, u need the reverse. make sure u have rubber grommets on u'r module and NO contact to the firewall. mopars are funny that way.

SOURCE: 1990 FORD F 150,SPARK ON THE COIL BUT NO FROM THE DISTRIBUTOR

i had the same problem. there is a group of wires that go by the distributer and branch off to the distributer and go towards the front. when i would jiggle it the van would die. it ended up being a pinched wire.

SOURCE: 1984 Ford E-150 Econoline van It has no spark

check the wiring around the distributor i don't know how simular it is to a 1990 ford crown vicktoria 5.0 engine,
but on this car, there is a little two 2 prong plug beside the distributor no wires coming from the plug it's self , it plugs into the wiring harness it works like a fuse.
if you remove it or if it has melted the car WON'T START, no fire the link can be removed to keep the car from starting for testing purposes (fule pressure ect.)
when you wouldn't want the car to start

1986 dodge with a 2001 360 dodge magnum motor 600cfm edelbrock carb, air gap edelbrock intake. new plugs (e3s) new wires new coil new ballast.. is all in time.. wont start help


Are you getting spark? You've put a 2001 engine into a 1986 body. The 2001 engine ran with an engine control module (ECM), the 1986 doesn't have that. The 1986 probably has an electronic ignition module that works with the 1986 coil and 1986 reluctor/distributor. You may want to compare the two distributors and the two coils.

Where is fuel pump harness on a 2000 escalade


DTC P1351 Ignition Coil Control Circuit High Voltage
The enhanced ignition system uses the crankshaft position (CKP) sensor in order to provide a timing input to the control module. Ignition control (IC) spark timing for each cylinder is based on this input. The control module provides the ignition timing signal to the ignition control module (ICM) to control the ignition coil. Each timing pulse detected by the ICM allows it to energize the ignition coil. A large secondary ignition voltage is induced in the secondary coil by the primary coil. This high voltage is switched to the correct spark plug by the distributor.
This diagnostic trouble code (DTC) will set if the VCM- (vehicle control module ) detects an unusually high voltage on the ignition timing signal circuit.
Diagnostic Aids
Intermittent test -- If the connections and the harness check OK, monitor a digital voltmeter connected between VCM terminal C3 pin 9 and C4 pin 18 while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change. This may help to isolate the location of the malfunction.
An intermittent may be caused by any of the following conditions:
?€¢
A poor connection

?€¢
Rubbed through wire insulation

?€¢
A broken wire inside the insulation
Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
If a repair is necessary, refer to Wiring Repairs or Connector Repairs in Wiring Systems.

Car turns over but i'm getting no spark what could cause that or how do i fix that so i get spark


Start with the ignition coil. It should have power to it with key on. Should be battery voltage on the primary circuit to the coil-that's the coil positive terminal. If the coil is good, it could be a bad ignition module-the module cuts primary current to the coil when commanded by the engine computer.
It could be several things-fouled plugs, bad plug wires, cracked distributor cap, bad rotor, crank sensor or pick up coil (inside the distributor), pcm. Test the ignition coil, or try a known good coil.

i have seen this problem on many dodge motorhomes , does the air cleaner have the electric device on it? if it does i suggest reverting the engine back to the old style distributor that does not require it as those tend to go out and cause a lot of problems,it is a fairly easy solution if you are mechanicaly inclined and you wont see many problems with the electrical system of the engine afterwards.the hardest part of this solution is finding 1 of the older style distributors

1991 dakota intermittently stalls or will not start after being run for 30 minutes or more of running.


When it does this you need to check if you have voltage ( spark ) going to the end of the spark plug wire, but it sound to me like your pick up coil is going bad, pick up coil sit under the distributor cap under the distributor rotor same size as distributor assembly ( black ) cheap$$, good luck, hope this was very helpful.

1988 Dodge Caravan ignition coil has no spark


replace the coil, cap, and rotor. if that doesn't work, replace the ignition control module (pick-up coil), but you'll need to remove the distributor to replace it.

check the 2 wire connector to the ignition module. It may come loose causing intermittent ignition shutdown. replace and tie down connector to prevent vibration.
