I have a 1992 Pontiac Grand Am, and when driving one day, the car just died. We had it towed to our house, and really didn't fool with it for a while. Recently, we cranked it up, and it started fine, but it ran really rough like it had jumped time. We pulled the timing cover off, and the timing marks lined up perfectly. So, then we started thinking it was a blown head gasket or a cracked head, and ran a compression test on it, and all was excellent there. The plugs have fire, although it looked a little weak. (I don't know of a safe way to test plugs, my brother was mad at me when he got shocked though). The coil pack is only a few months old, and I replaced the plugs and boots when I replaced the coil pack. The fuel filter has been replaced. Now, I have to replace the fuel pressure regulator because my brother tried to unscrew it when it wasn't meant to be unscrewed. It just popped off! Anyhow, I don't know what to do with this thing. I know I need to get it running again real soon though. Any help would be greatly appreciated! Thanks!
