1. Disconnect the negative battery cable.
   
2. Disconnect the fuel hoses from the pump. If necessary, tag the lines to assure proper installation.

Before installing the fuel pump, it may be helpful to rotate the crankshaft so that the cam lobe is on the down stroke.

Take the starter back and tell them it is a piece of junk. I just went through the same thing, 3 starters before I got a good one. Every time they tried blaming my car. Never the taiwan starter. I finally got a good one, still going. Hope this helps.

If you have any other fittings on the valve cover (pcv valve, breather tube etc) you can put a hose into the valve cover through that hole and fill it. (slowly...most have baffles inside). I have seen engines filled through the dipstick tube also (takes forever though).
Once you get oil in there, bring it to a shop and have someone show you how to get the fill cap off so it is easier next time.

The information you need is here, hope it helps.

There is a switch under the dash on the steering column that could be bad. Also, check fuses and if you have a tow package, check the connections under the rear of the vehicle for corrosion or grounding out.
