So.... how do you check the fuel pressure?

The Yaris is built on a budget and how often do the fuel pumps or injectors go bad?

This is true, but definitely frustrating for a diy'r when you want to rule out fuel issues. Fuel is rarely an issue with toyota engines, typically coil packs are tje cause of misfires in high mileage engines

I saw it happen to my cousins Yaris. She had a 2SZ engined one. I'm not sure if it was a chicken or egg problem but she had coils 2 and 3 fail at the same time and i think new plugs as well at the dealer. I wondered what had gone bad first. Bad plugs damaging the coils or bad coils that fried the plugs?
