Car won't start, getting way to much fuel

My car hasn't ran right for about a month now. First it was hesitating and had a surging idle. But for the past couple weeks it won't start. Here is a list of parts I've changed: coil, cap rotor, ignition module, wires, IAC, EGR, MAT, TPS, MAF, CTS, fuel filter, injectors and fuel pressure regulator diaphram. When I crank the car it will kinda sputter for a few seconds if I give it gas but it won't really start. I can smell alot of gas. I drained the oil once and there was a ton of gas in it. The fuel pressure is real high, even when I try to adjust it and it drops of quickly. Thats why I changed the regulator diaphram but it still didn't help. Before I changed my old injectors I tried testing them and I blew my 10 amp injection fuse. I changed the fuse and since then is when the car stopped running even after the new injectors. Did I hurt my ECM or something else when I blew that fuse. Please help, I'm running out of ideas and parts to change.

There is little chance that you damamged the ECM. It's possible, but not at all likely. I'd take a close look at the injection circuits. If a wire is grounded, you'll get full fuel spray whenever the pump is running.

Anothee item you didn't mention is spark plugs. If the engine was so flooded that you got fuel in the oil, it's very likely that the plugs are fuel fouled and won't fire.

Just some info for you : My 88 GTA started running really rough
all of a sudden, very rich, with gas in the oil. After all sorts of checking this and that, it turned out to be the computer. So, if possible, you might get a junkyard computer or borrow one from someone, and replace the computer, see what happens. Just a thought. I ended up paying a mech $454 for all the testing of this and that, plus the new computer!
