It is not the catalytic converter. These type of problems require a diagnosis to determine the cause, anything else is pure guessing and a waste of money. The advice I have is to learn how to diagnose a no-start problem, or take it to a shop that will perform this for you. If you do take it to a shop, make sure you can duplicate the problem for the technician.

I am having the same exact problem . it is not the fuel pump, has a new fuel filter, no boad vacuum lines, and is not throwing a code to read with a scanner. ive had it at 4 garages and no one can tell me what the problem is but its so random with its stalling out. some times mine starts ight back up sometimes it takes a few minutes. I have a new alenator, battery , and catalytic converter. I can not get the car to duplicate the problem for the technician as its so random when it does it and the wont loan me a guy to put in my back seat for up to a week. so do you or anyone have any ideas about this? its a 90 buick century sedan
