that and make sure you have at least 35psi of fuel pressure. but when i had my z i had to clean the connectors every 6 months due to corrosion.

then i got smart and used dielectric grease AKA (spark plug grease). no problems after that.

Thanks for the info. Ill look into both of those but it sounds like the bcdd valve. Anone have any ideas about my tach from what it does in the vid? Im assuming its dead but not 100% sure.

 

ya time for a new tach. before you do if you have a friend with a cheap tach hook the signal wire up to it and see if it does the same thing. if so you have other issues.
