My Tacoma has an issue- where after disconnecting the battery, the ECU forgets the air/fuel adjustments that keep it running smoothly and it has to relearn- if the intake becomes dirty/too much buildup over time. I haven't ruled out this possibility?
I did check all the fuses- everything was good.
I'll have to check that wire for voltage when cranking over. After grounding the spark plug against the battery, it refused to spark when cranking over. When I did check the ignition coil signal wire, I'm pretty sure it read that it was cleanly grounded the entire time. I will have to test again and look for the +2v when cranking.
