We replaced the cyl. coil to address the misfire. The shop is telling me that the fuel pump control unit has gone out. It has been ordered and it should arrive today or tomorrow. I am tempted to swith the low pressure fuel sensor before the more expensive control unit. Thoughts?
I would too. Because a lot of the time, you can not return a special ordered electrical component. The low pressure sensor is not that expensive. Let me know.
