2008 e450 class c pats light blinking NO Start **SOLVED**

Let me think about this. In the "good ole days" these vehicles were much more simple, didn't have bells and whistles, had fewer speed transmissions, little or no electronics. Now, I understand Sprinter based RVs have a "limp home" mode when something malfunctions and limp apparently is an appropriate description.

The result: on a motorhome like mine they only got 9 or 10 mpg. OH! They still only get 9-10 mpg. The difference was, I suppose, shorter life and a vehicle that the average guy could work on with basic tools and knowledge. My first Class C's water heater lighted with a match and it worked flawlessly. It's water pump was....get this...made in America as was virtually everything on it.

Yes, vehicles will run up a lot of miles anymore without as much maintenance and with sometimes fewer problems. I just wonder if we haven't past the point of diminishing returns. Self driving RV anyone?

I am ***SO*** Glad! We had a case a couple years ago where an anti-theft kept a Class C from starting and it was a mess! Couldn't get off a campsite, coach was towed, shop couldn't start it, forget what all. Went on for a good while and though I forget the cause and outcome (if it was ever posted, so THANK YOU for telling us), but it went way beyond annoying.

Turns out that the fuse box under the dash was dangling and causing all of the issues

My thoughts also. Go under the hood and with the engine off unplug one at a time anything that looks like it goes into a control box. Look closely at the connectors and using a spray specifically for electronics spray each connector. That's what I would do. You say that you have had the battery disconnected, that will reset the computer also. I would also unplug the main fuse and check other fuses directly related to the computer. Double check those battery cables and ensure your ground cable to the battery and the frame is clean and tight.

I had a diesel generator once that stumped the best and it was a bad ground to the frame.

Have you used a code reader yet, my 08 Wrangler had a clock spring fail, it's the round device that controls airbag and all controls on your steering wheel, and I was getting flashing codes and

tones until I replaced it. It had an effect on my ignition switch as well.

That was with it running to show what happens

According to photo you are starting in drive. I'm probably wrong BUT why are you starting unit in drive rather than park??
