Customer Question
Hi I have a Monaco...
Hi I have a Monaco Coachman 2003 with cummins ISM 300 engine. I have been a while in a campsite in Portugal. Today I was supposed to leave but when I tried to start engine stop, warning, and check engine started to blink and I also got the same sound as when I don't have enough of air in the system. It also seems that the Jacks don't go down

Hi Wayne I,ve started it as normal two days before my problem started. I tried to start it with the door open and step out. It didnt start, then I closed the door and it started, was going in 1 minute then it stop and the problem started. Seems that I can't get any EMC code cause I don't have a diagnostic switch

Hi Wayne
My friend didnt hear the ticking sound. He was mistaken. There was a lot of noise from the road.
It was when I was laying under the motorhome I noticed that it was no ticking and then I checked if there where any power and found out there was nothing.
Customer reply replied 2 years ago
Can the ECM be stucked in a fault code wich I created when I tried to start with the door open?
Technician: Wayne, Journeyman replied 2 years ago

Hi Thank you for that

disconnect the battery for 15 minutes

Can't find any fuse who is specifiad as fuel pump in Monaco Book. Have to go out on internet and look. Have in battery compartment pump dag and ABS pump.
Technician: Wayne, Journeyman replied 2 years ago

Hi

What you can do is run a Temp hot wire to fuel pump wire

to get it going and moved to a repair area

Ask Your Own Medium and Heavy Trucks Question
Customer reply replied 2 years ago
Have been out on the internet and as I understood the fule pump gets power directly from the ECM. If I put a hot wire is there any way I can damage the system. If I start it in fault mode.
Customer reply replied 2 years ago
Are there any other way to reset the Computer
Technician: Wayne, Journeyman replied 2 years ago

Hi

That is correct, I forgot about the fault mode

So,no don not do it

need to get mobile Mechanic to hook up to the engine computer
