Pick-up coil how to replace pick-up coil

the pick-up coil is inside the distributor housing this is what your looking for

put other pick up coil back! sometimes new ones can be no good also! just cause it new don't mean it will work!

The pick up coil is located at the base of the distributor and plugs into the ignition module. The pick up coil's purpose is to sense or "pick up" the pulses of the distributor and tell the ignition module when to fire the spark plugs. The most critical part of the replacement of the pick up coil is to make certain you properly mark the orientation of the distributor to the engine block and the rotor to the distributor base. When you successfully make these markings, you will not need to check your timing when this job is finished. Keeping this in mind, here we go: You will need to purchase a replacement pickup coil and a rubber o-ring gasket that will replace the o-ring located where the distributor shaft enters the engine before you start this project.

The pick-up coil/stator is easily replaced in a dodge distributor, and once you have removed the distributor cap and the ignition rotor, then just dis-connect the wire connector from the pick-up coil/stator and lift it straight up and out of the distributor, and the distributor does not have to be removed or dis-assembled to replace the pick-up coil/stator. There are two alignment tabs on the pick-up coil/stator that will match up with the distributor cap when the pick-up coil/stator is properly installed. Here are two images to help assist you.

Check under the distributor cap and look at the connector where the ignition module connects to the pick-up coil/stator, and if it is dark or burnt looking then replace the pick-up coil/stator or the entire distributor. Here is an image of the ignition pick-up coil/stator and you will notice the white connector, and when that connector becomes dark or burnt looking then the pick-up coil/stator is faulty.

check the throttle wiring maybe worn out as the engine gets hot it loses connection

While you was replacing the distributor did you look at the pick-up coil and module inside the distributor?? If not then either one of those two things will keep an engine from starting. The crankshaft position sensor mounted on the bellhousing will also cause the problem. To check the pick-up coil in the distributor with an ohm meter;remove the dist.cap and hook up one side of ohm meter to a good ground, and the other lead to the pick-up coil terminals Flex the leads by hand to check for intermittrnt openings. The ohm metershould indicate infinitr resistance. If it does not the the pick-up coil is bad and needs to be replaced. Connect both leads from the ohm meter to both terminals of the pick-up coil and flex the leads> the ohm meater should hold a steady value between 500-1500 ohms. If not then replace it. If it does replace the module under the coil in the dist. base. Hope this will help you.

PICK-UP COIL (HEI)

1. Isolate 2 pick-up coil lead wires. Remove pick-up coil connector from module. Connect ohmmeter to either terminal and ground. See Fig. 4 . Connect pump and apply vacuum to test vacuum advance unit. Replace vacuum advance unit if inoperative. Connect ohmmeter to pickup coil terminals. Operate vacuum pump and observe ohmmeter throughout the vacuum range.

2. Attach ohmmeter to one pick-up coil terminal and distributor housing. Set ohmmeter to middle scale. Operate vacuum advance throughout vacuum range. Reading should be infinite at all times. If not, replace pick-up coil. See Meter "A" in Fig. 4 .

3. Connect ohmmeter leads to pick-up coil connector terminals. Operate vacuum pump to ensure proper operation throughout vacuum range. Flex terminal wires by hand to check for possible intermittent defects in wiring or connectors. Pick-up resistance should be 500-1500 ohms. If resistance is incorrect, replace pick-up coil. See Meter "B" in Fig. 4 .

NOTE: Activation of the vacuum advance may align trigger wheel tooth and pick-up coil pole piece causing ohmmeter pointer to deflect. This
deflection should not be diagnosed as a faulty pick-up coil.

ck for the pick up coil working.unplug pick up coil remove wire from ignition coil to dist lay coil wire still connected to coil about 1/2 inch from ground turn key on take a jumper wire and jump the wires on the engine harness side of the connector if it has a spark replace the pick up coil in the distributor

Check the pick up coil. This is the part right under the rotor. Your best bet is to buy a new distributor. because sometimes the shaft in the dist gets worn and makes the ring gear on the shaft rub against the pick up coil. you will see like a brown powdery residu under the rotor and all over the pick up coil if it is rubbing. If the pick up coil is bad you wont have spark or injector pulse.
