It will turn over but won’t start. It is getting fuel and sparking. I just had the exhaust repaired. It ran for a few minutes but when I started it up again it shut off and won’t start back.
My suggestion would be to replace the fuel filter. Maybe some sediment in the gas tank got sucked into the filter when you ran the vehicle on low fuel. This sounds like a textbook issue of a clogged fuel filter.
When you work on your car and it does not work after you are finished, you broke something in the area where you was working, the crank position sensor CKP is probably near the back side of the engine, I would guess that a wire is broken in the exhaust area where you was working, do a very good inspection.
