SOURCE: 97 dodge ram no spark

then i would replace whats called the hall effect sensor its that black plastic plate you see when you take dist cap off. just pull rotor and lift up the sensor.dist cap is what holds it on.also under the sensor will be a stamped sheet metal piece that looks like the top of a castle wall. make sure its not loose on the shaft.if it is then new dist will be needed

SOURCE: 1999 dodge ram 1500 318 engine no spark no signal

Check the ASD relay in the fuse box. Swap it with the starting relay. If the engine fails to roll over. Thats your problem. If not, check and see if your fuel injector connectors have voltage to them if not its a bad PCM. Hope this helps.

SOURCE: on the coil how many volt is a coil should have

A standard ignition coil normally generate about 15,000 - 25,000 volt depending the requirement to spark the spark plugs. The input volt should be 12 volt but the amperage should run about 400Va.
So now what is the question?

What is the hot side of the coil so I can hot wire to see if I can get spark also to check to see if coil still is goood


The wire that goes to the distributor is the ground side of the coil. The other side is the positive side. Be careful if you plan to connect 12 volts to this terminal on the car, as most cars have a ballast resistor between the 12 volts and the positive of the coil. If you connect 12 volts directly to the coil you may burn out the coil. You are better to use a multimeter to check the coil as that will not damage it.

NO SPARK OUT OF COIL. HAVE REPLACED COIL, NO 12 VOLTS IN TO COIL EITHER. NEW DISTRIBUTER,CAP,BUG,PLUS,AND WIRES. HAVE FUEL. BYPASSED WIRES AND PUT 12 VOLTS IN TO COIL AND STILL WILL NOT START? IM STUMPED


usually those coils are pulsed at the ground wire end of the coil. So you could have 12 volts in. The question is...do you have 12v out the ground end?
If so then the coil pulseing unit may be bad.That signal,should come from the distributor....or maybe from the ECU Processor.

Will Not Start


Check the distributor for cracks and check the rotor inside the distributor, it may be worn out.

Getting 12V on the ground wire to the coil. Any


the coil has two wires. one side is hot 12 volts the other side is the side that is pulsed to ground to create the magnetic field to induce high voltage.. with the key on not running you should see voltage on both wires... disconnect the plug from coil and recheck you will have power only on one wire that is the hot wire.. hook back the plug now take your test light ground clip and clip it to the positive terminal on battery. then back probe the wire to be pulsed.. have some one crank jeep and you look at test light.. looking for kinda dimm flash... if so that tell you you should have spark if not the bad coil.. if you don't see flash then probable bad pick up/... let me know

No spark between the distributor and coil


You need a voltmeter or test light to find 12 volts on one side terminal of the coil--the other side terminal goes to the distributor. If both sides have 12 volts, then the points may be dirty. If no 12 volts on the coil, trace that wire back to a resistor block on the firewall--check both ends for 12 volts. If still no 12 volts, check the ignition switch. Have you checked for a blown fuse?
Generators are usually nearly totally enclosed and long with several terminals sticking out. Alternators are shorter and wider with lots of ventilation slots and several terminals on the back. They also have a prominent fan behind a smaller pulley. You might see if you can find a Haynes service manual for this car if you are on your own.

If you have a 12 volt test light put the point on the positive lead to
the coil and the ground lead to a good ground ( Negitive side of battery ). Then turn the key on. If the test light comes on then you have power to the coil. With power to the coil confirmed have someone crank the engine and put the test light on the negitive side of the coil. The light should flash at a rapid steady rate. If not then your pickup in the distributor may be bad. If no power to coil with key on or when cranking you may have a bad ignition switch.
Another way to test for spark is to remove the coil wire from the dist cap and hold the end close to a ground ( 1/4 inch away) and
have some one crank the engine. If you get a good spark but no
spark to the spark plugs you may have a cracked dist cap or a bad rotor. If no spark at coil wire use a wire in place of the coil wire to check for spark. You may have a bad coil wire. Good luck. Neil W.

GM 2.8 Liter Engine ECM/Coil will produce spark


does a 85 have a ECU unit ??? sounds like it could be the switching transistor thats either under the coil or inside the distributor should look like a black plastic casing with 3/4 wires running to it then to the coil look at this first as often motor runs ,stop for a quickie somewhere and jump back in and engine will not fire up ,classic symptons
