Loss of power

Hi,

We need to check and see if there are any codes. There a number of things that can cause this but I attached a repair that is pretty common depending on the DTCs. If you don't have a scan tool then most parts stores can pull them free of charge.

This guide will help:

Let me know what you find and we can go from there. Thanks

I was finally able to get a scanner on it p0231 p0470 p0478 are what is coming up I replaced the ipr and back pressure sensor. Also replaced the fuse that was blown now it won't even start. Cranks over but wont start.

Hi,

I attached the info for the P0231. Check the inertia switch and make sure it is not tripped. Then run though this diagram and I am sure you will find why it is not starting.

So I replaced the relay also the back pressure exhaust sensor and the tube. I also replaced the ICP and the pigtail that goes with it and still nothing. now it wont even turn over.

You mean you did all this and now the engine won't start? If this is the case, there has to be something that you touched is either not connected or not right. Are you able to pull codes again? If you have an open circuit code for one of these then that will point us in the right direction.
