Are chip died as well. We have removed the chip and confirmed the ECU is working properly and now the car starts, runs and idles like it should! By chance do you know how to replace the battery with a CR2032? Also by chance do you know if we replace the battery will are tune still be on there? Tim THANK YOU!I keep re-reading the first post and grabbing more info and also answering my own questions.
Tell me more about the tune. If it has a quarter horse chip with a tune the tell they are bad is key on the fan kicks on high. When my chip failed in my 95 it acted a lot like that video now that I think about it (this was around 2015 ish) so memory is only so good.
I've convinced myself at this point it's the tune lost or is a QH chip the battery has failed.
