Car cranks but won't start after fuel pump replacement - Toyota Yaris Forums

Are you getting a spark? You have fuel, but what about spark and compression. This likely has something to do w/ the earlier issue regarding the fuel pump but i'm not sure

EDIT*. Just re read your first post and you have spark. Anyone know of a reset switch anywhere sort of like a crash cut off found in ol Fords? I can't see why it's not catching if you have compression, fuel and spark

No - nothing like that for the Yaris. If the plugs are firing and injectors are clicking, the car should be firing. If it is not, then it should smell mighty flooded. If it does not, then either the injectors are not really firing or the pressure is too low to push fuel through them.

I'm going to get a compression tester and check compression tomorrow just to eliminate that as a cause. Are these cars known to jump timing out of the blue? It was seriously all fine before the fuel pump gave out I'm so confused... I've checked everything so far except for compression so I'll give that a try tomrrow since that's all that's left...

With a timing chain, it is very difficult for timing to be an issue. If you try to crank it for a bit, does the exhaust smell like gas?
