Jessy79

hi i am having a problem with my 79 5.0 mustang. the engine wont fire it cranks but wont start. i just started the car earlier today and it was running fine, but i went to replace my instrument cluster and got it all hooked up and it doesn't want to start now. whats weird is the ignition buzzer doesn't come on when the ignition does, but only when you hook up the battery. then you turn the key and the car acts like the ignition has been on for awhile. it has been doing this for a day or two after i went down a puddly road, which also reminds me that the tach stopped working after i went down the road as-well. i am in desperate need of help!!! i use the car as my daily driver! any help would be appreciated please and thanks
