Question about 1987 Dodge D150

1 Answer

I have a 1987 dodge power ram 150 that will not get fire past the coil wire. I have replaced the wires, plugs, cap, rotor, distributor (single plate coil with no vaccuum advance) and battery (optima). OH and the coil, twice now. Neither of the new ones work and the old one doesn't either. If I turn the key to on and hop up in the engine I can run a wire from the neg of the coil to the ground of the engine and get a spark. If I run the coil wire to the ground and have my wife crank it, I get no spark off the ground. I get 11.66v at the coil and at the negative post. I ran jumper cables and boosted that to over 12v and still nothing. I also replaced the computer behind the front drivers fender which has two harnesses, one for 14 pins (not all wired though) and one for 10 pins. I am just at a loss right now how I can get voltage to the coil, yet not to the wire connected to it. The last thing I replaced was the computer, before that, the distributor because the coil plates were shot and there was a little chunk missing off the distributor. I figured just slap a new one in and take care of both problems. It started twice then died on me. There is a sensor that arc'd out underneath the coil with three plugs. Kinda looks like a dryer plug in your house. I believe it ran without it though when I found it it was off. The wire was bare metal but I covered it with electrical tape, and it looks still good at the connection. PLEASE HELP!!!!

    Well, it has tension and the engine does turn over. However there is no spark as the engine turns over. If the coil is not producing a spark, it doesn't get to the distributor. Will the car turn over but not get power past the coil if the ignition is bad? That doesn't sound accurate, an explanation would be more helpful please.

I have a 1987 Dodge dakota and can't get any spark?


You need to see if you have voltage at the coil with the key on.
Make sure the check engine light comes on when you turn the key on.
If not, check the ASD relay in the engine compartment.
You will need a book and a meter to test the other components.

Ignition coil isn't getting any electricity, so it wont send a signal to the distributor cap, therefore not sending elecricity to the sparkplugs..... This is on a 1992 Dodge Ram 150, 2 Wheel drive, with a...


Hi, Hope I can help you.
I do not know how you have checked for spark, but lets start from the beginning.
Lets start with an ignition systems check.
1. I want you to remove the high voltage coil wire. ( That's the wire in the center of the distributor cap.) Using a good pair of insulated pliers. I want you to hold it about 1/4 inch from a good engine ground. Now you will need a bit of help from a partner. Get them to turn the key and crank the engine. You should see a bright blue and well defined spark. Ok, If you have spark I want you to slowly move the coil wire away from the engine ground. As you do this I want you to pay attention to the coil tower. (The coil tower is where the other end of the coil wire is attached.) What your looking for is arcing and sparking at the coil tower. If this happens then you need to replace the coil with a new one. If this does not happen then your coil is working fine, and we will have to move on.
Note if you do not get spark from the coil wire replace the coil.

2. Ok if you have spark now we have find out if the spark is making it to the spark plugs. How are we going to do this? By checking the rotor, distributor cap, spark plug wires and spark plugs.First lets remove the distributor cap. This will allow use to inspected the rotor and the distributor cap. What your looking for is, cracks, carbon tracks and wear at the tip of the rotor. On the distributor ,look inside the cap for cracks, carbon tracks and wear on the terminals. If you find any of this replace the distributor cap and rotor. ( Note if you have any doubt of the condition of the rotor or the cap replace them.) Next lets check your spark plug wires. Lets pull off one of the spark plug wires from the spark plug side. Now inspect the wire connection for a white crusty powder. If you find crust replace your wires. Now you should check all of them the same way, but if even one has corrosion replace them all. You are going to have to inspect the wire its self . Going down the whole length of the wire. Holes cracks burn Marks and other damage. Once again if you find any damage replace them all.
I hope this will help you and good luck to all the read this FixYa

Have a 91 dodge ram 3500 van and have no spark. tried new coil cap and rotor plug wires can anyone help?


Sounds like a bad distributor. Make sure the distributor has not sheared the shaft. Remove the cap and rotor, and make sure there is some tension on the shaft in rotation.

If it does, using a voltmeter, check that power is reach the coil.

Also ensure you have the correct firing order on the cap and the cap is installed properly and sealed.

Won't start


take a little bit of starting fluid and spray into the air cleaner and try starting it. if it fires this way you have a bad fuel pump. and also take the cap off and spin the motor over to see if the rotor is moving because i have seen the distributor shafts in these older trucks break off so they will not spin

No spark to plugs or coil.


Do you have power to the coil with the key in the run position and when cranking? (ignition switch)

Pull the coil wire out of center of distributor cap and lay it close to where you unpluged it from distributor cap, and turn over engine if coil is good you will see the spark jump. If no spark coil bad.

My 2002 dodge ram van cranks/ won't fire


The coil is inside the distributor cap. It is a flat round plastic plate the cap pushes downn on when you put it on, with wires going to it. Disconnect the wire connector, remove the distributor cap, remove the rotor, pull up on the wires till the coil/plate pops off the distributor housing. Replace with new coil, reverse procedure to assemble it all.
Be careful to clean inside the distributor when you have the coil out, as it does not come apart often, and sand and dirt builds up under the shield/plate of the coil, especially in dusty areas, so blow it and wipe it out good. Put the new coil in. Put the rotor on, then the cap.
Replace all this stuff if you have trouble with the coil.
Also, replace spark plugs or clean them, as misfires and mis timed spark can cause one or more plugs to really carbon up fast and bad.
