Did you inspect the ground wire for the MAP , that is mentioned in the P0106 article Link I posted.

 

Swapped out the fuel pump relay with the same results. Ran for ~7 minutes then shutdown with no CEL. I'll follow up with inspecting the ground wire again tomorrow. Thanks!

 

Why not test the relay trigger?

 

Perhaps a fuel pump pressure test, maybe the pump is dying a slow death.

 

My 06 was doing the samething i filled my tank with 91 and added fuel injection cleaner to it and it died a few times then around 3/4 of a tank she farted then had no more issues.
Not saying this your issue but like I said had same symptoms.

 

Thanks for the tip on higher octane fuel with injector cleaner. I had quite a bit of fuel in the tank before adding 5 gallons treated with Seafoam. Been trying to get higher octane treated fuel thru the system. I still need to hit the MAF with cleaner but she's running twice as long as before: ~3 min to now ~7 min!

 

Looking back over this string, I checked into donbrew MAF comment where I replied that my car wouldn't run with the MAF disconnected. Upon further research on a different MAF blog, I read that the car should run and sometimes even better when disconnected. Does anyone have some insight on whether this is true or not. My car will not run with the MAF sensor disconnected.

 

If it does run , usually after someone puts the air filter box back in place and forgets to reconnect the MAF sensor, a code is set and the check engine light illuminates . It will run and stumble very rough, definitely not better.

Thanks Oldblue! I got 5 gallons of higher octane fuel with injector cleanser into the tank along with MAF spray for the sensor. I'll check ground wiring too this weekend. She's been a good workhorse in our fleet of panel trucks and wants to get back to work. I just love these panels for hauling/delivering beverages all around town!
