The first thing you should check is when the vehicle fails you takes out a spark plug and sees if they are wet, if this is the case the carburetor is the problem, also check the following when the fault preserves, disconnects the hose that sends the fuel to see if it pulls if the prable does not do it is in the pump.

Hello, thank you very much for your help, I'm going to prompt today after I get out of work
I let you know what you have according to the steps you gave me
thanks

I send you a cordial greeting. Regarding the fault, you have to check the electrical system that can also give you problems to the current intermittently if the system is platinum in some cases stick or the condenser is short -circuited. luck

Thank you for your help and the problem was that the Cañito of the Naphtha tank was covered by the Mugre the mechanic told me that I have to clean the conbustible tank if I do not want me to go back
good I send you a hug to Ticoman and Kikemec
