Engine lite stays on all the time and how do i change fuel pump on my 93 dodge spirit?

Okay....this is for the fuel pump:

1. Make sure the negative battery cable is disconnected. Have a metal cup handy to collect any fuel that may spill.
   
2. Place a drain pan under the oil filter, then remove the filter with a strap wrench or equivalent.
   
3. Disconnect the fuel and vapor lines, catching fuel that spills. Dispose of any spilled fuel safely.
   
4. Plug the fuel lines to prevent leaks.
   
5. Remove the attaching bolts and remove the fuel pump.
   

1. Clean the fuel pump and engine block gasket surfaces of all old gasket material or dirt.
   
2. Position a new fuel pump gasket against the engine block, then situate the pump in position over the gasket with bolt holes lined up squarely. Install the retaining bolts and tighten them to 21 ft. lbs. (28 Nm).
   
3. Connect the fuel lines to the pump (always start fuel line connections by hand-before using a wrench to tighten) and tighten the fittings to 175 inch lbs. (20 Nm).
   
4. Clean the block surface, check the gasket, then install the oil filter, tightening it by hand only. If the gasket is damaged, replace the filter. Refer to Section 1 for the proper service procedures regarding oil filters.
   
5. Start the engine and check for leaks. Check the crankcase oil level and refill as necessary.
