I have a 4 cyl. Chevy Corsica that needed a coil pack replaced. There are two of them, one goes with the odd number cylinders ( 1 & 3) and the other goes with the even number cylinders (2 & 4) Typically, the number 1 cylinder is the firing cyliinder and if that coil pack is gone, the car should not start. My car is a rarity that actually started and ran on the 2 & 4 cylinders.
The 4 cylinders have a coil pack on top of the motor.The 6 cylinder's coil is inside the distributor.The 4 cylinders have a coil pack on top of the motor.The 6 cylinder's coil is inside the distributor.
Then there is a no spark condition and engine will not run. If it has more than one coil pack it will miss on the cylinders controlled by the defective coil pack.
The COIL PACK TOWERS are numbered : coil---3---4 pack--2---6 plug---1---5
A coil pack assembly is a coil that controls 4 or more cylinder using separate igntion wires for each. On a Taurus it will control the 6 cylinders.
coil pack
No , it has a coil pack for the 6 engine cylinders
what is the fire order for a coil pack and cylinders for a 1998 toyota tacoma sr5
The coil pack is 3 coils and cylinders are paired ,1&5,2&6,3&4,.The 2 cylinders fire together at the same time ,one on compression on and one on exhaust. The firing order is 1,4,2,5,3,6 .
May have failed coil pack, there are 3 coil packs and 3 leads, 1 coil pack fire 2 cylinders in wasted spark. Isolate the failing cylinder and test the input voltage and signal to coil using a led test light or noid light. If signal is present- replace the coil pack If no signal possible crank/cam sensor issue or ecu
I figured this same thing out by moving the coil pack around. Leave the plugs in place and try it on different cylinders to see if you get spark. I had been fighting to solve my issue, and turns out it was a $50 fix to replace a bad coil pack that misfired on three different cylinders.
bad coil pack on cylinders, find or pull ignition wires and you can tell by no loss of power.
sounds like coil pack issue
