Easy way is to run the large out wire to a ground, one post on the coil to a ground and one to positive. Do not allow the large wire to actually touch the ground, have it just above the ground so that you can see a spark.
Warning: do not touch the large wire while the other are hot. It has a lot votage and could possibly cause you to get injured.
i dont know can u tell me
Well on a small block Chevy there will be no coil wire going from the top of the cap to a coil. What you can do to see the difference is go here.
well you first need to tell someone is it electronic ignition or dose it have points ??
Unplug ignition coils one at a time until you find the one that doesn't effect the rpm's.That's the one that's bad.
The 1992 Rangers have a distributorless electronic ignition system and if the ignition coil packs are an issue the resistance of them can be checked with an ohm meter to tell if they are OK.
bad coil pack on cylinders, find or pull ignition wires and you can tell by no loss of power.
Replace it with a new one.
ignition coil is mounted inside the distributor ,underneath the rotor. BE CAREFULL, the ignition coil to 1994 galant is expensive .study it before just yanking out screws.It has a sensor plate inside and when you undo the screws in haste it comes apart and that controls the computer make break signal to tell were #1 is. Sooooooo, you then get to spend a lot of time figuring out how it goes back together. And guess what nobody but the Japaneese factory knows and now i do.,because i did this accidently. GOOD LUCK!
If you have the 4.6 liter ( 281 cubic inch ) V8 it has spark plug wires and ( 2 ) coil packs on a 1997 Ford Expedition . It has EDIS ( Electronic Distributorless Ignition System) ----------------------------------------------------------------------------------------------------- If you have the 5.4 liter ( 330 cubic inch ) V8 it has the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils for the spark plugs
I'm not a mechanic / technician but on the 1999 Ford Expedition I believe the 4.6 liter was still using the EDIS ( Electronic Distributorless Ignition System ) which uses ( 2 ) coil packs with spark plug wires , where the 5.4 liter has always used the Coil On Plug ( C.O.P. ) ignition system with ( 8 ) individual coils
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.
P1351 keeps coming out I have replace the crank sensor ,fuel pump,cam pickup,ignition module,ignition coil. It works about an hour when I shut the truck down for about 10 minutes it will not engage unless. I clear the code,what can it be?
