I am sorry for the long wait
can you charge the battery or replace it and get the engine to crank over physically and see if the engine will somewhat run on starting fluid or carb cleaner being sprayed down the throttle body butter fly ?
can you check and see if you have spark when cranking it over and fuel pressure ?
you need to connect a fuel pressure gauge to the test port on the fuel rail
lets see if another expert has any ideas
hang on another expert will reply back to you
Hi, My Name is***** have over 20 years experience repairing vehicles. I am a ASE Certified Master Auto Technician. I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.I also try to give all of the information you may need expecting a positive rating. If there is any reason I cannot get a positive rating please let me know.
I will try to assist. I am unsure if what a sudden stop would have done. Lets start with some basics.
I am attaching a picture of a mass air flow sensor. Can you just unplug it and see if it starts?
If it doesnt we will continue with these.
Do you know what fuel pressure was?
Do you have a solid security light on dash?
You stated you have spark. Did you have your friend check for injector pulse?
the p0443 won't keep it from starting. There is 2 crank sensors and a cam sensor that can keep it from starting. A scan tool is needed for further testing
