I moved your question to the car catagory.


Have you tried checking for codes with a scanner?


Have there been any other problems?

no I did not scan it. Two weeks ago I had to replace #2 coil.

Expert:  Neal replied 5 years ago.
Sorry for the delay in responding. I would scan for codes and see what you get. In cases where the spark and fuel pump is lost it is often the powertrain computer that is failing. Sometimes scanning it will give you a code indicating that or the scanner may not be able to communicate with the computer.

I have a MT2500 snap-on scanner and it says it can not communicate to ecu.
Expert:  Neal replied 5 years ago.
Then it is most likely going ot be a bad ecu unless you can find a wiring problem.
