Once you spray the carb cleaner and the engine starts and runs, how long does it stay running?

Turn the key to the ON position listen at the engine for the humm of the electric fuel pump. Do you hear it run?

Was any work done affecting the spark plugs? If so what? Were they put back in the original holes and orientated the same direction?

Do you have an inductive timing light? With it you can monitor the firing of the injectors. Have you had the engine computer diagnosed? Were the injectors checked for operation?

What HP is this engine?

no to all

Which engine is it?

Your engine is almost completely computer controlled. Without having the engine computer diagnosed, nor having any tools to diagnose it, there isn't much we can do. We need to check operation of the timing, injectors etc. Can you give me the engine model number?

Do you have the SystemsCheck gage? Are you getting any trouble lights? If not then the start assist circuit may have a problem. You will need to take the engine to a qualified repair shop with the diagnostic software to monitor the EMM (computer).
