Toyota problem with the spark

I have a Toyota Hilux 2.4 1999 The problem is the following that one when trying the spark is supposed to leave long and blue is orange, what problem can it be ????

Friend, it is clear that you have to change the spark plugs, but one of the most likely causes is that you have them fastened or faint, the first is because they simply fulfilled their useful life and the second is because you have to have some drip of some of your injectors (if your Hilux is injected) or bad regulation in the gyclers of your carburetor if it is that it is carbureated, this is causal. Here what you should do is change spark plugs and then see what happens.
I hope I have been your help and luck with your truck. greetings

What is the fault presented by the vehicle? To help you in something you have to say the fault your coil can be bad but in a vehicle with distributor you advance time and improve, that helps to diagnose the problem with the coil but seeing the color does not mean that this bad if it has no leak and the spark is long.

The problem is that it is consuming much conbustible and does not use carburetor is injected and has no leaks, they told me that it can be a coil problem, how can I fix that ???

Check the state of the air flow sensor if it were the feelings feelings in minimal running, jaloneos when making strength, explosions or something similar. Sometimes Fayan and do not give faya codes because ECU only records whether there is a signal below the acceptable minimum or more of the maximum value to certain intermediate RPM does not detect as faya if the signal varies.
