Rich. That is how mine works also. Now when I turn ignition on and bump the light does not come on. I believe the pump may have just failed even though I can not confirm 100% without putting a gauge on the pump. I have decide to go ahead and change out the pump. I was looking at the Fass Pump but decided after talking with and injector shop I trust to go with a Airdog FRRP. Mounts the same as stock pump but is a little larger to provide higher quanity of fuel to injector pump. I am planning on installing it in the morning so I will let you guys know how it works out. I feel better safe than sorry. Ray

I have change all filters. I have a warning light installed. When I turn on ignition but not starting engine the light should come on then cut off as it is a eletrical pump and pressure should build up with ignition swith on. As soon as I start the engine the light goes out. In my mind this tells me the lift pump is bad and that the injector pump is pulling fuel when engine started. The symtom I initally got was the mototrhome just seems low on power. I have not driven the Coach but maybe a mile or two since noticing problem so I think the injector pump is still good as it pulls fuel and no codes have shown up. I just want to be safe rather than let it go and mess up injector pump. Does that sound like I am on the right track?

Has anyone replaced the stock fuel lift pump on a 2000 Cummins ISB 5.9? I have this engine with a banks power pac and I am pretty sure the lift pump is bad. As I do not want to chance causing a injector pump failure I am thinking of replacing it with a FASS DDRP 02 pump. It is listed for a dodge appl. but the shop says it will work on the motorhome. Any sugesstions?

Thanks for the replys. I talked with Gaffeny and they were a huge help. It was the one at the rear axle even gave me the part # so I could keep the dealers here in Miami in line. I also must say as a new member I have found these to be the most informed forums I have read on any site. Thanks again. Ray

I have a 2000 Fleetwood Discovery on a Freightliner chassis. A few months back the parking brake warning light stayed on when I released the parking brake. The brakes were released and I took it to a Freightliner dealer. The tech informed me it was just the sensor and he could change it in two days. I did not have the time at that point so he said it would not hurt anything to drive. The light will stay on at times and other time go out. I now have the time to fix it and being a Diesel Mechanic for 30 years figured it would be easy. However I can not seem to get a solid answer on which switch needs to be changed. One tech said the switch is located at the rear axle, another said it is part of the push pull switch for the brakes, now another says it only a two wire pigtail on a box under the dash. Has anyone encountered this problem and could please tell me with which switch has to changed. I hate to take it back to Freightliner and pay the big bucks if it is a simple switch that needs to be replaced. Like I said the brakes always release it is just that the light will stay on intermittently.
