No Start - Water Separator

[airduds]

I removed the clear plastic bowl on the water separator and cleaned it out. Reassembled and started coach. It ran for about two minutes and then shut off. Will not restart. Is there some way to get air out of system rather than just grinding on starter?

There should be a primer pump on the motor. Pump away

Okay, found the pump (actually knew it was there but suffer from CRS). I pumped some, felt like I was just pumping against air. I stopped and opened what I'll call a bleed screw on the pump housing and got air out. Still no start but is this the procedure I should be following?

Pumping is very hard now and I don't get any air out of that bleed screw but still no start.

Finally got it started. Problem solved.

I had a similar problem so I went to a friend who works at a large trucking firm.
he had a simple jumper that connected to the battery and also fit the small pins on the electric pump plug. I set it up and in a few minutes my lines were filled and all ran great.

Very good post. This is a real life lesson on working on diesel fuel systems. Before you start working on the fuel system do some research and find where the primer pump is and where the bleeder screws are. When you get done with your work open the bleeder screw and use the primer pump till you have liquid with no air coming out of the bleeder screw. It will save your starter a lot of work and you some aggravation. I have a diesel electric fuel pump that I bought to fit between a tank and a filter. I bought it after I inadvertently ran my tractor out of fuel. It saves a lot of hand pumping.
