Hi, I'm trying to help a family member with 1991 Plymouth Voyager w/3.3 engine. We have already checked compression,plugs&wires.
We thought that it was the #3&6 injectors because we could not hear them ticking. We changed them but that wasn't it. Can anyone help with this please, Thanks.
Is it cylinders 3 and 6 that are not firing? As it is quite likely that the ignition coil is common for these 2 cylinders. Although the coil is one unit I think it has 3 coils that are shared ie cylinders 1+4 2+5 and 3+6 share each coil internally.

My apologies for the delayed response. I am going back to answer - unanswered questions. I have only been on this site for the past 4-months. Questions Posted have exploded (+55%) since joining. I do not know if you still need this information, but I am answering it either way.
I do not know if you have the 2.5L (4Cyl) or the 3.3L (6Cyl); however I have included both below.
For the 2.5L (4Cyl): Firing Order: 1-3-4-2 Cylinders: (back of engine) 1-----2-----3------4 (front of engine) Distributor: .....(back) .....1...3 (+).........(+)-screws .....2...4 .....(front)
For the 3.3L: Firing Order: 1-2-3-4-5-6 Cylinders: (back of engine) 1------2------3 4------5------6 (front of engine) Ignition Coil: (back) 6---3 4---1 2---5 (front)
Again my sincerest apologies....
