I think your on the right path with the fuel pump. Can you hear it prime when you turn the key on ?

Welcome to the forum by the way. And of course you'll need to charge or replace that battery first.

Replace the burnt fuse, my car had a burnt fuse that caused all sensors to work incorrectly and make the car go into fail safe mode.

this safe mode your talking about is it like the car isnt getting enough fuel to the engine?

i replaced the burnt fuse. Replaced the fuel filter & fuel pump but the car still starts up rough & idles very odd. & as soon as i hit the gas pedal the car dies. Thank you for your help.

in safe mode the rpm only goes up to around 4k rpm. The transmission will shift early. Are there any Trouble codes?

Zacharyzb1997

the code is a very small leak an evap leak. Ive got no smoke machine to find the leak. It just seems like the motor aint getting fuel to it.
& another thing i didnt do with the fuel pump was realse all the preasure & use a compression tool.

the car doesnt idle that high goes to 1 to 2 rpm & bogs down.

Evap wont cause driveability issues. Sound like u might have a plugged up exhaust. Press the fuel pump reset button. its on the driver side left foot wall.

Make sure all sensor are connected properly.
