Question about 1991 Plymouth Voyager

1 Answer

Two cylinders not firing.

Hey Chris,
I appreciate your quick response. I thought that it might be the coil also, but since i'm not familiar with these type of coils I figured I would ask someone who is. I just tried another coil,but there is no change. I can hear all the other injectors ticking but #3 & #6. They all have power going to the injectors, but no ticking or fire to the #3 & #6 sparkplugs. Any other idea's?
I appreciate your help, Thanks!

    Hi JD,

    Ok I am assuming you have removed the spak plugs and found you have no spark at the tip of the plug on cylinders 3 and 6 and as you have replaced the ignition coil already it looks that we have a fault with the control side of things.

    The ignition coil is controllled by PCM (Engine Control Unit). I think you may well have a 4 pin connector on the Ignition coil. I do not have any wiring diagrams so unable to tell you exactly what each wire is for, however one of the wires will be permanant 12V supply when the engine is running which is supplied from the auto shutdown relay and will very likely be the same colour as the common coloured wire to each of the injectors ( hope this makes sense).

    The other 3 are control wires for each internal coil within the coil which I suspect are switched earth circuits from the PCM.

    If you are able to obtain wiring diagrams I suggest carrying out a resistance test on the wires from the ignition coil to the PCM.

    If these wires are OK, I think you have a problem with the PCM.

    Regards Chris and good luck

Hey I have misfire problem with opel corsa(1997) 1.4gls which has v4 engine and i dont see any spark in 1st & 4th sparkplug what must be the solution for it?

these fire off of the same coil. check for power and ground at the coil if this is good then replace the coil. power should be at the coil with the key on and ground only when the computer grounds the circuit to fire the coil. if it was a crank sensor it would affect more than these cylinders and car probably not start.

Coil pack connection is physical: Coil 1 to Cylinder 1, 2->2, etc.

I am not sure if this is your question, but firing order matches spark to TDC (top dead center) on the power stroke. The design of the crankshaft determines this.

1-3-4-2 is common for most straight 4's. Cylinder 1 is closest to the crank pulley. I believe your coils are 'waste spark' which means it will fire two cylinders at the same time. When the coil fires, one cylinder is on the power stroke and is wanting this spark. The other cylinder is on the exhaust stroke at this time, and thus the spark is 'wasted' on that cylinder. But a cylinder with exhaust gas has high impedance, so most of the energy is delivered to the intended cylinder.

If your question was 'should I just connect 1->1, 2->2, 3->3, 4->4' [ yes!] vs. ' should I try to connect coils following the firing order' [no] then the answer is the first. The trigger wheel determines which coilpack fires when, you just need to hook up the wires number for number.

No i need to know on a ford v10 the firing order and witch one is coil J

The firing order is : 1-6-5-10-2-7-3-8-4-9 The 1 thru 5 cylinder are from front to back on the passenger side while 6-10 are from front to rear on the drivers side
I see in my research that the engine has a coil on each plug. However, I can't find any info on how the coils are designated. Just a thought though, if you are looking for coil J and J happens to be the 10th letter of the alphabet, maybe it's cylinder 10 ?

2007 Pt Cruiser I Changed spark plugs 2 weeks ago Bosch Platinum +4, car is non turbo 2.4 ltr engine. within 1 day engine light on cylinder 1 miss fire, read on the net changed plugs to Champion RE14MC...

remove the plug from the #1 cylinder, and install it into the #2 cylinder , and put plug from # 2 clyinder in to #1 plug hole, connect plug wires, and start up vehichle, and if computer shows misfire on # 2 cylinder , then you have a bad plug, possibly porcelin insulator could have a hair line crack in it, hope that this information has helped you.

Two cylinders not firing.

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.
