2008 Sedan no spark - Toyota Yaris Forums

EBeck · 01-29-2021, 12:15 PM

Hello, My wife's 2008 Yaris sedan suddenly stopped while driving. I turns over but there is no spark. No codes stored in the ECU. Dash lights look normal. I checked all of the fuzes. Both the camshaft sensor and crankshaft sensor work (Make AC pulses when the engine is cranked). The ignition relay is also working. Grounds were checked and look good. No rpm detected on tach when cranking the engine. If the tach gets RPM from crankshaft sensor I wonder if this is telling me that its the wiring for the sensor? I am all out of ideas! Please help!

Did you check that the fuel pump turns on and makes a sound?

I will check first thing tomorrow. Thanks. I dont have spark when I crank the engine so figured that would be the first issue to deal with.

Thanks Mazsive! You made me stop and think....and I realized that when I was trying to check for spark I did not ground the spark plug....so yea I found today that I do have spark. Yep I bet its the fuel pump! Thanks for redirecting my efforts! Will report back
