Are you experiencing a no start condition?

PO380 can be tripped by attempting to start on cold GP's which oftentimes occurs if key is turned numerous times in secession trying to start with another fault condition present. Computer eventually notes cold GP's so trips circuit A malfunction.

PO380 will clear itself after 3 successful start/run cycles (1 cycle = running up to operating temp and then cooling down) which typically takes 1-1/2 days if car is a daily driver.

If you believe this may have occurred I'd look at the other fault first.

I don't have any experience with PO120 so dont know how to advise you conerning it. The throttle is electronic, the sensor could be bad?

*edit*
e300D97's post is very plausible.....wasnt there when I began typing (phone rang). I'd follow his suggestion first.
