Hey how are you

is there a check engine light on ?

have you had a diagnostic scan and retrieved the fault codes ?

We need correct Fuel pressuer & good Spark for the engine to run correctly ?

Do you have a test light so we can check for spark ?

Do you have fuel pressure tester to check for fuel ?

are you looking at fixing this yourself or looking to know the most possible cause of this issue and taking it to repair shop for the work ?

Do you have any prior experience in electrical troubleshooting and testing with a test light for power & ground ?

Please let me know

Thank You
