Engine wont start, Please help! Ok guys today i did a big NO NO, i was installing my tachometer and i completely F***** up the installation, instead of hooking it up like i was supposed to i miss read the instructions and connected the white (dash lights) wire to the battery, i grounded the black wire, and heres were the IDIOCY comes in, i stuck the it was either red or range wire into the "Diagnostics" port in the engine bay, as far as i know those were the only 3 wires i connected, i also did some wiggling around underneath the steering wheel to look for the tachometer port. I was about done installing everything all i had to do was find were to put the tachometer wire and i still couldent find it. anyways at this point i was done trying to figuire it out, and got sick of turning my car on and off, i did that about 5 times, anyways i moved my car down to the end of the drive away, and after about 45 minutes i went back out to my car and the engine wont start, i can hear the engine rurring and stuff but it wont turn over, i checked the battery and the battery was perfect. By the way the carn turned on and off perfectly fine after i put the wire into the diagnostics, it was after i moved it down the street and about 45 minutes later that it wouldent turn on. I was told i either blew an amp switch or messed up the electrical, can anyone please help me out? I have work tomorrow and school is starting for me next week. I would appreciate any help, thank you so much..
