i completed everything and go to start her and all she does is turn over but dont start i pop the hood and find a blown F-Pump fuse so i replace it and try once more ......nada same thing thinking it may be the alarm i disconnict the alarm and try .....same thing nada ok so now i unplug the headunit and try nada same thing ..i plug the OEM radio back thinking that may be it ...nothing
did i miss something?? is there a fuel reset switch?? WHAT CAN IT BE

please help or share some ideas

thanks

ps.... great forum

 

only thing i can think of is if the factory unit has a alarm as part of it, it may have deactivated the ECU when you removed it, i know some security systems do that.
