I need some help - I've got rough starting issues. This has been intermittent for the last few years but has been happening pretty steady for the last week.
Truck is a 5-speed 1985 4Runner.
Battery is good (bought a year ago, load tested last month, and on a tender all night, every night), starter is a month old, and a couple of months ago I installed a starter relay (the truck didn't come with one and I was getting intermittent starter operation).
Codes are 6 and 10:
Quote:
Code 6:
No engine revolution sensor (Ne) signal to ECU
- Ne being over 1000 RPM in spite of no Ne signal to ECU
- Defective Igniter circuit
- Defective Igniter
- Defective distributor
- Defective ECU
Code 10:
No starter switch signal for ECU w/ vehicle speed = 0 and engine RPM > 800
- Defective Vehicle Speed Sensor (VSS)
- Defecticve main relay circuit
- Defecticve igniter switch to starter circuit
- Defective ECU

It cranks ok, usually catches pretty early when cranking but then seems to run on only a couple of cylinders for a while. After a bit you can hear something that sounds like a relay click then it smooths out. When it's running rough I have to add a lot of throttle to keep it running. When cranking, if I don't catch the first firing with some throttle it'll die quickly then it's a lot harder to start (the video is of a second starting attempt).
Once all this shenanigans is done it runs really well.
Here's the video:

Any ideas?
Thanks!
