Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 5 months ago.

O2 sensors won't keep it from starting. A totally plugged fuel filter can.

The problem can be a loss of spark or fuel. You can check for
spark at the plugs with a spark tester.
You can check fuel pressure with a gauge and both of these tools
should be available to you at your
local parts store for rent or purchase.
You need to check for any stored codes in the computer with a
code reader or a scan tool.
The code reader only gives the codes and definitions, where the
scan tool gives you all
the needed data to diagnose the codes.

Only code was o2 and p0442. Which neither will kill it replaces filter
Expert:  rpmdiag replied 5 months ago.

That code is an EVAP leak, it still won't stop the car from running.

Please check what i suggested earlier.

Thanks again, and please rate me 5 stars and keep this link for when you need me again later on.
