It was on before this started,hasn't come back on since.this has been going on and off for a week
Expert:  Jon replied 1 year ago.

Ok, can you get it to not start? If so, when it doesn't start, there's a plastic cap on the fuel rail. Can you remove that cap and depress the valve core with a small screwdriver while someone cranks the engine and tell me if fuel sprays out?

here is an update,I replaced both the fuel pump and filter. still it keeps cutting off.the fuel guage flickers from 1/4 tank to zero ,then it cuts out or off completely.
Expert:  Jon replied 1 year ago.

Is it just the fuel gauge that drops to empty or all the gauges go to zero like when the key is off?

Customer: replied 1 year ago.
just the fuel guage

then when you try to start it it says out of gas. wait thirty minutes and it cranks and does exactly the same thing.added gas didn't make any difference
Expert:  Jon replied 1 year ago.

The fuel pump itself and the sending unit have different grounds, they don't share a ground. Is it not running right now?
