The even #s should face the front of the car.If your standing in front of the car facing the coilpack it goes like this:
rear of car
351
426
front of car
yup
rear of car
351
426
front of car
yup
THE above sequence is exactually how it is on my car as we speak.wlaukaitis:
Hello,
Accoring to Alldata for a 1986 Buick GN
Coil: 153
426
Engine: 6 5
4 3
2 1
the coil's top numbers being towards the firewall and the engine's bottom numbers being towards the radiator, confused yet? eek!
thank you for the above coil/pack module wiring diagram,unfortunayely my wires seem to be all connected correctly.CallMeMud:
Here is a piece I submitted to GNTTYP.ORG on the correct way to wire the coil pack/module: http://www.gnttype.org/techarea/engine/ignitionmodule.jpg
If it was running perfect before you may have a problem above or you have a couple of wires crossed. If it isn't that you may have a bad module still. Have seen them bad right out of the box!
i may have fouled a plug but should'nt have any reason too.CallMeMud:
Blue can go to any of them because they feed off one common wire if you look closely. The gap problem doesn't float here. Nothing wrong with that. You didn't foul a plug though did you? That will make it run like crap. MAF good? You didn't unplug the ECM and forget to plug it back in? What chip setup do you have? If you have a Max-Effort and plug the chip in backwards it will run like **** (don't ask how I know) and ruin the chip. eek!
