MY L300 V6 3.0 STALLS WHILE DRIVING, THEN AFTER A FEW MINUTES STARTS BACK UP

2001 Saturn Astra • 120,000 miles

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.

Check bank one(lh) frontO2 sensor and circuit and bank tw0(rh) rear O2sensor and circuit. They may be bad heaters may not be working.

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?

Yes Sir I do. Is the crank shaft position sensor next to the oil filter?
