Hello and welcome to JustAnswer!

It sounds as if some preliminary steps have been missed. You mention both spark and fuel but I'm unsure if both were actually tested and found to be missing. If both are truly missing then an engine controller problem is likely.

Have you both physically checked for spark and also found there is no fuel pressure using a gauge?

Customer: replied 5 months ago.
i did check both.

Does the engine light do a bulb check and go out when the key is first turned on?
