My sister has a 1988 Chevy celeb wagon 4cyl that would not start one day after work. I brought it home got under the hood and found that it was dumping gas down the throttle body. I did some asking around and found that the likely problem was the fuel pressure regulator or the injector so hoping for the best i pulled the regulator and it looked really bad so i replaced it. This didn't fix the problem so i also replaced the injector, that did it. It ran for about 2 days then all the sudden would not run again. I then checked the spark that it was getting and it was a week little orange spark so i checked the coils and they had great blue spark. needless to say i replaced the plugs and wires. It still wont start.
Please if anyone could tell me what i am missing or what to try or check out i would really appreciate it.

The chances are really good that you got the wiring out of order. This would mean that the plugs are now firing right, but at the wrong time.
You have the fuel situation sorted out, you know you have fire, all it needs is for it to be at the right place at the right time....
What I don't know is if this engine has coil packs, or a distributor (neverhad to mess withthaton one of these before). If it has coil packs - the cylinder numbers should be marked by the connections. On a distributor system you have to line the engine up on top dead center, and find number one, then follow the firing order. (It doesn't just go "1, 2, 3, etc...)
I'd bet my last beer that the wires are out of order! The plus side of that is that it doesn't cost anything to fix... The downside is that you have to figure it.

found out about a day after i posted this that i had a short in the wiring for the fuel pump so sometimes it would have pressure and then as the engine would turn over and move a round it would lose power to the fuel pump. thank you for the help guess i should have pulled this thread a while ago.
