Question about 1993 Saturn SL2
You will need to do a fuel pump pressure check. You will need to borrow a gauge or purchase one ($40 to $50), attach it to the fuel injector rail test port, it will have a little black cap on it, turn the key to the run position. Your fuel pressure should be in the range of 45 to 55 lbs.
The knocking noise is a little peculiar, check the engine oil for proper level and smell the dip stick. It may smell like gas, if it does, change the oil immediately. The gasoline has diluted the oil and is to thin, causing the knock.
Let me know.
