Hi:
If you don't describe how the problem began, I don't have much to say. Did you change a crankshaft sensor and do you know why it causes? Or that I carry you. What symptoms I had. Did you wash the engine?
I suggest that if you have someone a friend with scanner or a workshop nearby, check what the ECU or computer is told that must be OBD II standard.
The ECU stores the last data I lived before the fault, and the fault code.
You can check wiring, connectors or fuses battery etc but the probability of hitting is low.
You must differentiate whether it is a spark or fuel sominstro or the aranque at least.
Scanner is the solution, there is no magic, it is technology.
Luck
