the 626 has sat for upwards of 2 years and wont start, the check oil, battery, engine lights are all one. I have replaced the spark plugs and recharged the battery im wondering if something may have eaten some wires that are critical or where to begin to look in the ventalation system for a mouse nest or something on that order. the car turns over like a dream but doesnt seem to want to fire up....please help with whatever you can!!!

Determine if its fuel or spark do below

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil,distributor pick-up coil, ignition control module, cam and crank sensors-
