Hi everyone,

I have a 2007 Toyota Mark X, and the other day i started it and it immediatly died on me.

After inspecting the cause, i figured out that I was not getting spark to none of the cylinders due to the IGF wires measuring 0.17 volts with ignition ON and 0.3 volts while cranking. (Supposed to be 5 volts)

Every fuse inside the cabin and under the hood was checked excluding the hidden high amp fuses. I don't know what else to check.

The voltage was measured directly from the ecm pins.

Any advice or suggestions would be greatly appreciated!

Thanks in advance!
