still has problems starting

[bdavies11]

About a week ago i posted here about my 2000 camaro having troubles starting. In my previous post i mentioned that i replaced the battery and had a new crank sensor put in but still continued to have problems starting. A couple guys suggested checking the fuel pump and we did. The fuel pump checked out fine and for the past week it has started right up everytime and i was starting to feel comfortable with her again until today she wouldnt start. :-( My step dad seems to think its just a bad/loose connection somewhere and is going to bring some equipment from the shop to test it out with this weekend. If u guys have any more suggestions or help for me id really appreciate it. Thanks.

How does it run in closed loop?

closed loop? i dont know what that means.

After the car starts taking info(Bianary code i think?) from the cats to adjust A/f mix. Maybe someone can say diff.

Also, I would check all wiring up to Crank sensor, and to ground. A decent multi meter will do everything. Why was this sensor replaced? No codes?
