Hooked up battery backwards on 1992 explorer, not getting any spark. Traced everything back to the coil pack. Could it need a new coil pack


most likely fried the ecm. run 12 volts to coil pack positive side a see if you get it to crank. oh by the way check that battery is installed correctly and that it is putting out 12 volts

I have a 1990 f-150 with a 300 straight 6 cylinder. I am getting voltage from battery to coil but no spark coming from it. I have replaced it and distributor also and still no spark. anyone got any ideas?


Replace the coil and ensure that you get the correct coil voltage for the vehicle Coils come in to voltages Straight 12 volt coils that start and run on 12 volts and other that start on 12 volt and run on 7 volts. Check if it needs a resister with it.

1971 chevy truck will just shut of any given time. not getting spark. let it sit few minutes starts right up?


check that you have the correct voltage coil installed. IT sounds as if the coil is overheating and failing. There are 2- 12 volt coils on the market. one is a full 12 coil and the other is a duel voltage coil. The wiring allows to start opn 12 volts and as soon as the engine starts runs on 7 volts through a resistor.If you are running a12 volt use with resistor coil on straight 12 volts system you will have problems as you describe

I have a 98 vw jetta gl ABA and it wont start run.


I would check for spark on the ignition coil and the spark plug. If no spark, check the power and signal to the ignition coil. The ignition coil large wires are 12volts power and the other three is a signal to electronic firing circuit from ECM. Testing the power is easy, for testing for trigger signal, use a 12v LED test light.

I have a 1995 dodge van which wont start due to no spark I have tested right at the coils sec. I do have injector pulse but no pulse at ign coils primary there is power at primary of coil at first we...


A test light connected across the coil primary leads should flash on + off when engine cranks(coil sparks when 12v turned OFF due to collapse of magnetic field).If you get pulsed 12 volts,and no spark from the coil,the coil is bad.If you don't get the pulsed 12 volts,trace back to find out why(the PCM turns the coil ground on and off,12 volts comes from switched IGN source)

1998 Ford Explorer, 4.0 SOHC No Spark. Engine will crank but it won't start. Replaced the Crankshaft Sensor, Coil Pack, & Spark Plugs. Still no spark. What next?


You are at thhe right trail what controls spark is coil pack crank sensor sparkplugs and plug wire but the most important is power . I mean 12 volt connections and ground This includes checking fuses you need a simple volt meter doesnt have to expensive or fancy just to pick up 12 volts let start with fuses in the engine juction box (there not mark to what it belongs to) make sure none are open. especially fuse 19 and 24 , next go to the crank sensor make sure the tabs are snuggly on now to the coil pack there is a red and light green wire this comes from ignition and feeds 12 volts at the coil pack measure that voltage is it 12 volts if not correct it this is from ignition switch ( you can make a tool that feed 12 volt with a wire and a fuse in series and attatch it to battery and the primary wire this is known as hot wire) next go to the ECM wiggle the wires see if that get a connection going if not go back to the ICM here are the wire you are to measure the tan light green, this is from ECM and it is pulsed it measure 5vlts to 0 volts switched then measure the tan orange the same thing 5 volts to zero,then tan white again 5vlts to zero. any one of these 5 to zero fails you fix is the ecm

MY CAR LOST POWER, STARTED BACK UP AND ONE PERSON TOLD ME TO CHANGE THE SPARK PLUG WIRES BECAUSE ONE OF THE 4 CYL WAS NOT GETTING POWER, WE DID THAT BUT IT STILL IS SPITTING AND SPUTTERING WHAT COULD IT...


Follow the number 4 cylinder spark plug wire back to that ignition coil.
Verify that the wiring is getting voltage approx 12 volts with key on and that ground is good
Make sure that the wiring going to that coil is not corroded, broken pins or breaks in wiring

Just finished 12 volt conversion on 49 V8 flathead. Starter engages but engine won't start. Appears to be getting fuel.


You might not have spark as the 12 volts needs a ballast resistor or the points burn out preytty quick. 8 volts at the coil in run with the points open and 0 with the points clsed and battery voltage at the coil when cranking. coil wire near the intake manifold while cranking should jump at least 2 inches. Closed points should be 0 volts at the neg on the coil. pos and neg should be the same 12 volts with the points open. if not either the coil or the points are bad. The condenser can fail and no spark with all the rest right

Not getting spar to wires


check ignition fuse.if okay.remove one of coils connectors using a test light .turn ignition key to on position .terminal 1 on the connector to coil is the first to left with the locking tab up. then remove the ignition module connector terminal 4 is 12 volt supply.4 terminal to the right with lock tab up.connect test light to ground.take the pointed end touch both the terminals for 12 volts with ignition on position.if getting 12 volts.you have PCM PROBLEMS OR CRANK POSITION SENSOR..IF GETTING NO 12 VOLTS YOU GOT A BLOWN FUSE OR GROUNDING PROBLEMS.
