It's back

Hey guys, i had the 1997 GTP that would randomly die, and i had the O2 valve cleaned, and replaced the CPS. The car ran great for about 2 weeks and just last night it didn't want to start, and when it did it ran for like 2 seconds and died, even if i applied gas. Why is the problem back, and what else can i do to fix it?

did yo udo the job yourself or did a shop do it. The crank sensor has to be checked for air gap clearance between it and the balancer. if it's installed wrong, it will rub and eventually fail again.

I had a body shop do it. They were going to charge me $45 to do the case learn after i installed it, or for $15 more dollars they would do it all, so i just let them do it.
