1993 Chevy Corsica 4 cyl Front Wheel Drive Automatic

old faithful finally died. It was acting funny but would still run. It does not even want to start at all now. I was lookin at the car book and it has fuel filter or something injection adjuster repair. This book is like reading a foreign language. It also says something about the battery. The car is turning but will not fire up. Please help.

Do below and then get back to me.

Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself, distributor pick-up, control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

I had all of that done the fuel pump had to be replaced and the fuel filter had to be replaced. The regulator was taken off to check the fuel pump and now it will not go together the right way. It keeps leaking well shooting fuel out of the lines because the one line just "snaps" in and then you got to tighten a bolt on the line underneath and when you do that it comes loose. Do you have any suggestions? Should it take more than the "o" ring on the top line or do both require that ring?
