I don't know if this is anything helpful, but last week after oil change, I put some Seafoam in the intake and days later the check engine light came on. When my wife got the truck home, checked with the code reader and came up as P0300, a random or multiple misfire. I did check the spark plug wires with my little tester/pen and there were two that looked "odd" and not firing correctly. Also, yesterday, there was a whining type of noise coming from the rear of the vehicle, I am supposing the tank area. The fuel pump is back there, and it never made this noise before. With the battery light and not check engine light coming up, I feel that it may be an electrical issue with the fuel pump. No codes present on the reader, either. If anything else is new, I will let you know. Thanks again for advice.

do you have spark at the 2 your coils and if so is it blue spark or yellow if any spark at all? because blue spark is good yellow spark not good.
