Sits and idle all day even when pushing gas pedal to the floor?

It sounds like the car is in limp mode, we should run the codes to see what comes up, also please check the throttle cable to make sure it is connected to the throttle body.

No codes showing. Started this morning and ran well until I shut it off then wouldn't start an hour later ran battery down so now have battery on charge. Will check fuel pressure next. Thanks

Please let us know what you find. We are interested to see what it is.

Checked everything and decided to sell it to the junkyard. Thanks, fuel pressure at specs.
