One inside fuel tank, and one along inside of "frame" rail near the tank, I think.

I'm not sure why you have a carborator on 89 regal, BUT if you haven't try replacing the spark plugs and wires you might want to try that if you have factory wire (the carbon composite wires it comes with are terrible). But that might help. If not maybe check and see if your fuel pump is working properly (ex. weak pump, bad fuel line, ect...)

Check ignition wires, too. They can get old and let the spark leak out.

ya could be a bad filter. or maybe your injectors are getting bad.

change the idler sensor,,,easy to do takes five minutes,,follow instructions to a tee,,,i recommend a bottle of lucas fuel additive to every other tank of gas it does wonders and keeps enjectors clean

Try disconnecting the injector you think is bad. The car should start just run a bit rough. If you're not sure which one is causing it, disconnect one at a time, and then try start it. Other option if its not too hard to change the injector, swap it with one of the others if the same problem occurs at the same cylinder the injector is not the problem. If the problem is now at the other cylinder, the injector is bad.

there is no fuel filter in the engine compartment only the one under the car near the fuel tank.

when you remove the fuse cover, the diagram and list is generally posted to the inside of the cover. If you lost the cover, you may try a junk yard and see if you can find a fuse box cover.

Sometimes depending on the how the damage was incurred

When you said checked the fuel filter, did you mean changed the filter?? And does the Battery hold 12 volts?? Check the battery to make sure it has 12 volts. If you have a second car, take the alternator off and bring it to a auto parts store like Auto Zone and they can test it free of charge and battery too. Change the fuel filter, if both are good then check all the fuses and relay, Pay attention to the fuel pump fuse and ECM fuse. If everything has is good then it's going to be a bad fuel pump, which is located in the gas tank. That requires to dropping the tank to get to the fuel pump. Good luck and hope this helps.

I have seen many time that the rug/mat may be preventing the accelerator to be completely depressed. Check that...

why do you want to take off that keeps the spokes centerd
