So, I had a 99 for a about 6 months before a woman hit me and caused a four car accident. The car was totaled but I kept it anyways. I went out and bought another 99 a few days ago. The mustang was super cheap because it only drove backwards. Once it warmed up it only went about 10 mph but it would go forward. We figured it was the transmission and bought it anyways. We took the good transmission out of my totaled mustang and put it in the new one. The only difference between the two mustangs were that one had Trac Control and ABS the other did not. Now it goes forward and backward. Good? No. Because now it does not start. We have to bypass the ignition by jumping the starter. Then it will start fine. Before messing with the tranny it always started fine. It has an alarm on it with a remote starter. Before replacing the transmission: The Remote Starter would attempt to start the car, then cut off and the alarm would only set sometimes. Now, all the car does it set off the alarm. And get this! The car thinks it's started! The lights come on and it beeps for the seat belt, but it's not on. Also, the theft light blinks constantly, even when started. But, I don't think this is a problem because my previous mustang did the same thing except it always started. Anyways, the ignition wasn't bad before, so I doubt it is now. The check engine
light is on. We've already tried unhooking the battery to reset it. It didn't work, and we've checked for blown fuses. Please help, I need a car!
Also I forgot to say, by not starting I mean it does NOTHING. it doesn't turn over it doesn't click. it does nothing but turn lights on!
