trouble starting

[cbane1]

Back in November, 2008 the heater/ac blower started making a horrible noise that sounded like the bearings going out. I started researching to find a new blower. I found one online for 1/3 the price of the local dealer. I studied where it was located and figured that I could replace it myself. All it was to install was 4 screws and one connector. When I started removing the old blower there were several different wiring harnesses keeping it from coming out. I had to unplugg one and try to work around the others. I finally removed the part, got the new one in, and re-attached all of the connectors. Since then I have had 3-4 occasions that the car would not start. Seems to be getting fire but no fuel. I got the crazy idea to look under the dash and make sure all of the connectors were connected. Everything was in order and I tried to crank the car. It cranked right up, but with the engine light on. As soon as we cut it off and cranked it back up the engine light went off. This has happened a few times and we just jiggle the wires and the car will crank. I am afraid that it will get worse. I am wondering if I may have stretched a wire too much and am losing connection to a relay or fuel pump. I do not know what the other wires in the harness go to so I am not sure where to start. A wiring diagram may help but I'm not sure. Any suggestions.
