1999 forester manual
Went out to start a couple of days ago and only cranks. Good and strong.
The long and short of it is no spark from the back 2 terminals coming off the coil pack. cyclinders 3 and 4.
Front 2 jump 1/2" or more to ground.
I don't have a code reader nor a full blown schematic.
The coil pack has a 4 terminal connector.
Using an oscilloscope I found the front most terminal on the coil pack jumps from zero volts to 12 volts in time with the cranking.
I assume this drives the functioning half of the coil pack. I found no other terminal doing this.
If I knew which pins from the ECU fed the coil halfs I could at least cut my troubleshooting in half.
I read somewhere about an intermediate ignition driver module but not sure my 99 has such a thing. If it does, I did not locate it.
Can anyone recommend a good source for an official full blown shop manual?.
I used to have this info but my old laptop died and darned if I can now locate a source.
If worse comes to worse, can I order an internet copy somewhere?
