What a coil pack plug looks like

The coil pack is where your spark plug wires hook up to. (Not on the spark plug but the other end) the plug will actually be on the ignition Module under the coils

No spark out off spark plugs

If your car has one wire coming out of the distributor at the bottom going to the coil, you can use a test light between thet wire and ground to see if your coil is getting a pulse. If it has a coil pack, then you might need to clean the connector on the coil pack. follow the coil wires from the plug back to find the coil pack. If your car has points in the distributor, you can connect the test whole circuit by hooking the test light across the points. if it's a coil pack, you might replace the crankshaft position sensor to see that does it. also, use the test light to check power to all fuses.

Got a new tach ,my car doesn't have one, how do I hook it up to a '90 buick 3.3 with electronic ignition? The "instructions" only show how to hook up to standard ignition.

Hello! Your vehicle is equipped with a distributor-less ignition systems; C-31...Does your engine have a "coil pack"? As in two cylinders per coil? The coil pack has a two wire connector at the top which is Ground and +12 volts...At the bottom are 2 connectors...The one on the left is a 4 wire and to its right a 2 wire...the one you are interested in is the 4 wire connector...Reading from left to right...Pin 1=Ground...Pin 2=Reference voltage...Pin 3=6X...
And Pin 4=Tachometer
...Hook the Tachometer wire (probably a green lead) to Pin 4...There is the possibility that the ignition module has a Tachometer input connection...If so use it...If not use Pin 4...

For coe pack

I'm fuessing that your refering to the coil pack. The coil pack has the plug wires coming out of it and they connect to the spark plugs. Theirs a 7 wire electrical connector hooked to it and they are key on power and a ground wire one for each cyclindrt going to the engine control module. As the computer grounds these wires the coils fires the cyclinders connected.

Coil pack problem

So I assume you never disconnected the bat. when changing the coil that is not good ....I would say buy another coil pack and start over and make sure to disconnect the bat.......Check all wires going to the coil for breaks or worn or burnt marks in wires before hooking up new coil

Need directions on how to replace ignition wires and coil pack on 95 olds 88 royale.

Set your new coil pack beside the old one under the hood. Be sure it's sitting the same way. Take the wires off one at a time, and put them on the new one. Then, remove the bolts and wire connection from the old coil pack, and hook them to the new, bolt it on. Then, simply remove the plug wires one at a time. Find a new wire that is closest to the length of the old one, and install it, and continue doing this until you have changed all six.

Not getting spark

Testing the coil packs.

1. Get an INSULATED wire and hook it to a ground on the car.
2. Get some one to help you
3. pull a spark plug wire off the coil
4. hold grounded wire close to, but not touching, the part where the spark plug wire connects
5. keep hands away from coil and have your helper turn the engine over ( start car and turn off)
6. if there was a spark between the wire and the coil pack it is good. if not, the coil pack needs replaced
7. replace the spark plug wire
8. test the rest

Number 5 coil pack has no power to it

I don´t see why it should have taken all day !

Yes, this sounds,..... if true? that the problem is in the wiring to the coil pack. ( Faulty coil packs are the most common problem ! )

The next multiplg on the loom, from the coil pack feed, should be disconnected and inspected, and checked for feed, and so on.

Might be worthwhile swapping over 2 coil packs, just to confirm there diagnosis was correct.
If they were not..... the misfire will change cylinders.

Hope this has been of help to you.

Good Luck !

A FixYa rating would be appreciated ....Thank You !
