I have a 2000 Honda civic LX. My check engine light came on the other day. The radiator fluid had recently been refilled and I think it was overfilled because some of it bubbled out. The car is running fine, but now the hood won't close/latch completely and the check engine light came out. Could this be a possible cause of a check engine light coming on or is it probably something else? Thanks.

I have a 1999 GMC Sierra Full Size Extended Cab, 5.3 Liter V8 Engine. My issue which just started yesterday. Vehicle started in the morning moved it around the yard for a few minutes. Came back to it later in the day. Vehicle would not start at all. I gave it a jump start and it ran for less than 1 minute before the engine began to miss and then it shut down completely. You could watch the charge on the battery move right down to nothing. So not taking a charge for some reason from the alternator. It will maintain a small charge from a battery charger just enough to turn over the vehicle to start it. Original battery in the vehicle. The green indicator light on the battery is not present and has been in the past. Is the battery just to the point that it will not take a charge or should I move to the alternator? I have looked for blown fuses with no success.
