Bad icm causes the rpm to bounce around . And of course a no start.
Was not referring to speedo bouncing.
um ok since ive been through this exact problem. fuse 15 keeps blowing due to the alternator. which lead to having to replace the fuse instantly all the time.
how can the car start if there is a blown fuse that keeps getting shot from the alt, which really powers and charges the car electricals.... hhhmmmmmm.
So you guys think it's just a coincidence that the speedo and tach bounce at the same time and the dash lights dimmed and went out and the causes for these are separate? The scenario you guys are suggesting is that fuse 15 blew and the ICM went bad simultaneously. While it's possible, it seems highly unlikely.yes, i can agree on this too. when my dizzy went bad, it did this as well.
And to JDM_SPEC_SI-R, the OP stated that the battery (and alternator fuse) are fine. IF correct, the engine will start with a good battery even if fuse 15 is blown. This is not conjecture. It's a fact.
Therefore, wouldn't it be most prudent to start by looking for single causes for all problems. That's exactly what my suggestion did.
So OP, what are the answers to these very simple questions?
Do the hazard lights or horn work?
Have you checked the battery ground wire attached to the chassis in the engine bay? Is it loose or corroded?
