could anyone possibly tell me where the rev limiter is in the front electrical box,and if there is anyway to diagnosis it.My gtx will crank over,the dash seems to show all the right info,I get all the right beeps when lanyard attached,but it won't spark at the plugs,have grounded the plugs and nothing.I replaced the ignition coil.I have no fuses blowing.I am stumped,any help would be greatly apreciated.
