Picked it up Friday drove home Parked it put some stuff from the old one in it
Went to start it turned over but nothing happened no pop spit or anything.
Went into the house for 15 minutes came out tried again started right up but lots of
messages which finished with it going into to limp home mode.
Got up this morning hoped it would start Fired right up ran great but check engine light
was on
Got to work and called the dealer and brought it in They put it on the machine and found the
check engine light had gone out because the problem had cleared itself
They went back and found the codes that showed the problem and the way they explained it
to me was the high pressure fuel pump must have had some type of blockage that cleared itself
and that's why it wouldn't start Once it cleared out the blockage all was good
Drove around for an hour all went well
It's a gas 6.2
I had a 2018 before and this is a whole new ride Very comfortable!!!
I'll post pictures as soon as it warms up enough to stand outside
