I disconected the fuel filter and had my brother crank it, no fuel came out. We left t alone for a few minutes then he cranked it again then fuel did came out this time. Is my fuel pump bad or will a bad crank sensor do this kind of symptoms. I would really aprecciate if I get some help.

Scan for codes and check fuel pressure first. Clean throttle plate on both sides with choke cleaner.

Those codes for the 02 sensors have been o there for a while like for a year. Will bad 02s cause this symptom. Like right now its at idle then suddenly dies. If I wait for 10 minutes sometimes less, it starts back up

I worked on tons of those cars and never had a bad o2 sensor cause those symptoms sounds like a bad crank shaft position sensor I have replaced tons of those for those symptoms. They dont always set codes when they go bad. Do you have a multimeter to do some testing?

You test it when it wont start and it should read 800-1200 ohms.
