Question

New fuel pump new ultinator in 24 hrs done at nissan. Pick up car it works great. Shut it off it wont start again

Answer 1

Hi there,

If you have a code P0725 this code is for the engine speed signal in the TCM. This comes from the crank position sensor. I would check and make sure the crank sensor isn't leaving a code when it gets hot or if the car is losing this signal. Then when it cools off the sensor starts working again. This would prevent the engine from starting.
