Starting Problems 1996 Jeep Grand Cherokee Limited 5.2 8cyl

I've already replaced Crankshaft Sensor. Here is sequence of events. I filled with gas and drove home 6.8 miles. Didn't dive for a few weeks. Decided the weather was cool enough to replace drivers door panel grommets because panel was falling off. Since I had door panel off I looked at non working automatic door lock and disconnected it and used electronic cleaner and re-assembled it. I didn't try to start for another couple weeks. I added oil, some dribbled down side of engine. About an hour later I tried going somewhere and would not start. It cranks but wont start. The dash gauge for Fuel and Battery don't do anything. Then low fuel light comes on. Also overhead console only shows time and temp now. Plus the steering wheel is not locking. I don't hear fuel pump power up. But maybe it is already pressurized, don't know. Crankshaft sensor is replaced with one purchased at jeep dealership. Could the contacts gotten dirty when installing it? What other things might keep it from starting. I switched relays around and checked fuses in engine compartment. Any insight would be appreciated.
