1994 Other Saturn Models 4 cyl Front Wheel Drive Manual 200xxx miles

I have a 94 Saturn Sc2 Twin cam 1.9L 5 speed.
Recently I was driving and noticed while taking off in first and second the car would bog down a bit I didn't think much of it, thought I need to replace the spark plugs.
Later that night I noticed the lights dimming, So I shut the car off to restart it, It wouldn't start. Like the battery died. I got a jump when I started the car it was running real bad. Probably only 2 cyls running at this time. I parked it. Towed it replaced the plugs and now it will turn over and act like its out of gas. I can feel it firing but it doesnt feel like all cylinders are firing in order or its flooding. I pulled the new plugs and they were black. Cleaned them put them back and tried it again. It seems like its out of gas or has bad plugs but thats not the case. Anyone able to help?

Do you hear the fuel pump come On for a few secs?

Check the fuel pressure with a fuel pressure gauge-could be the fuel filter or the fuel pump itself.

Do this spray some carb cleaner into the throttle body-if its fires up and die-do above and report back your findings-if not disconnect a sparkplug wire or 2 and ground it to the engine -while helper cranks it over-do you have sparky

No I don't have sparky. An I'm not sure I would even recognize the sound of the fuel-pump its always been a pretty quiet set-up. I'll do all of the above and let you know what I find. I know the fuel filter does need to be replaced though I was looking at that a few weeks back.

Okay lets try sparky-test the crankshaft position sensor's resistances and its output AC voltage-see below to include the ignition control module.

Okay we changed the fuel filter and we also used starter fluid instead of gasoline to spray into the throttle body. Yes it fired up and died but it was only momentarily. The car still won't start up. It seems like their is still pressure in the lines though we turned it over with the fuel filter unhooked the fuel didn't squirt out it kinda just globbed out. We switched it and retried it with the same outcome. There seemed to be pressure in the lines, after we hooked it up we uncapped a line and it squirted out pretty heavily. Now I'm back to square one and not on the street. Also where would the fuel filter be located on my car?

You have replaced the fuel filter and you're asking its location what's with this?

Injector/s are probably not pulsing. Check the fuel pressure

Oh man I apologize that was a mistype. I meant the location of the Fuel pump. Theres no pressure in the lines the propellars are pushing the fuel up but its not enough pressure so I think we narrowed it down and we are going to change the fuel pump. I'll leave a message here again if its not the fuel pump and thanks alot for the help. =)

The fuel pump is located inside the fuel tank

Would it be okay to leave the bad fuel pump in the tank and just add an In-line fuelpump? If so it would be alot cheaper for me to do.

I don't recommend this idea-its gonna have a hard time drawing fuel and the new pump must meet the pressure specifications.
