im assuming your car is OBD0... so is the little red led on solid when you turn the key?


the only reasons for that are bad grounds, or blown fuses... did you actually remove the fuse? have you checked it with a test light?

you could also check your main relay and fuel pump voltage...

So you're saying the CEL is on, but the fuse could be blown? So where is the power to light the red LED coming from? Think about that for a second.
