i was wondering if anybody here has the same problem...

but interesting is on a initial start up the tach works but when the car is running and im revving the engine theres no display... what could be my problem? any help would be really appreciated.. thanks...


theres an engine check light due to i removed the immobilizer..[media]http://www.youtube.com/watch?v=Pi9dlHNZprY [/media]&feature=player_profilepage << engine revving no display

but like i mentioned with the key on "ON" position the cluster starts up with the rpm display all the way at 9k rpm..

Annybody?

 

I'm guess a wire isn't connected right, but I could be totally wrong.

 

i understand that its the blue wire that feeds the tach signal... so can i test for voltage? if so i read that it should feed 0-5v when i do the voltage test when the car is on and i rev the car theres no voltage at all.. thanks..
