Fuel Trim's

Hey Guys

My MM is hard to start in the mornings so I hooked her up to my Laptop to see if any codes may be pending. Can you guys take a look the the stats and just kinda tell me what you guys think ??? ( See the PDF File Below)

Have you done anything to the car prior to the problem?

Have you done a load test on the battery to see if it is able to handle the cranking over okay?

If the battery checks out find out how much draw is comming from the starter as well.

Hard to start does not give a good explination of the problem.

Slow trunning over?

Take's a lot of cranking to get it started?

If your car is bone stock there have been revisions to the factory programming to remedy the cold start problem

No, it has a Reinhart tune. It will turn over fine it just seems like it is not firing for 8-12 seconds. After about that time frame she fires and cranks.

Question did this just start to happen?

Did you change anything reciently and the problem started right after it?

Sounds like a fuel issue? How old is your fuel filter?

On his PDF file he posted there are some fuel pressure readings but we need some guys on here that have detailed info about their fuel pressure readings to chime in and say if what he posted is normal or not.

I assume the fuel pressure is set to 60 to get more range out of the injectors. Mine is set to 39, which I believe is the normal setting. I don't see any reason it would affect starting, though.
