Starting Problem
Changed Racor filter last week and changed engine fuel filter
yesterday. Took it for a drive last night for about 15 miles and it drove better than ever. Much more power... Went to start it today to move it and it started fine. Let it run for 10 minutes or so then increased idle to help air up faster (bag leak in rear). Ran at higher idel for maybe 2 or 3 minutes then brought back to low idle and it cut off. Will not start at all now.... Checked the fuel shut off solinoid and it's working. Can hear and feel it. Checked Racor filter and it is clean. Tried hand prime pump and it appears to feel like it has pressure behind it. Could it be air in the lines or something real bad???? Thanks Chris Reed 83 FC35 SB Plant City, FL |

Starting Problem
Sometimes when going from high idle and especially under a load.
Then reducing to an idle is when the air gets sucked in. Recheck the fuel filter seals, and look for fuel leaks in the lines, filters, and around the injector pump.

Starting Problem
See if your racor filter is full, ditto for the engine filter. It
sounds like there might be an air leak. Another possibility is that a wire has come off or isn't powered to the fuel shutoff solenoid which is located at the fuel pump on the engine, a cylinder sticking up a little larger than a D battery. Check for 12v on the solenoid. If you remove this solenoid the engine should run, but you'll need to push down on the shutoff lever below it to shut down. Back to the air leak, the '83 has an electric fuel pump at the tank, the pitter-patter sound you hear toward the rear of the coach when idling. With this pump operating properly, you can open the racor slightly and fuel will run out, there should be pressure at all points up to the fuel distributor/pump on the engine at idle. If there is a leak, and it sucks air in at idle, likely your electric pump isn't working either. It is powered by an oil-pressure switch located beneath the dashboard, barely visible with the headlamp-door opened. You can start by manually priming the engine, if that doesn't seem to be it then loosen an injector line at the head and crank the engine to see if fuel sprays out as it cranks. If not you need to try priming again and possibly opening another injector line. This is BTW one way to purge air out of injector lines but the 3208 will usually purge as it runs provided the air in the lines isn't too bad.

Starting Problem
Jeff, thanks!!!
Removed injector line and cranked engine. Fuel came out like it should. Once air was bled engine tried to start. With a little cranking and some starting fluid she was up and running....smoother than ever... So I am I safe to assume that that was my starting problem? I shut down and started it up again fine. An hour later tried to start and it did take a little longer but it finally started...of course the air filter is off and the fuel filter on it's side so maybe that was part of the problem... BTW...I never did put BioBor in my fuel. When I pulled the filters it did not look like algea and when I pulled the new Racor after 40 miles it looked like new still....so I am hoping it was not an algea problem..

Starting Problem
If it took a little longer than usual to start, there's still a
possibility there is a small air/fuel leak allowing the fuel to drain back out of lines when it is not running. Try the primer pump before starting the next time and see if it fires right up. If so, that's a good indication it has a small air/fuel leak somewhere. Kerry --- In WanderlodgeForum@yahoogroups.com, Chris Reed > > Jeff, thanks!!! > Removed injector line and cranked engine.

The hardest to find leak is in the fuel tank pickup. The test to
determine if the tank holds the leak cost $1,000.00 in fuel.

Thanks Kerry, I'm going to check all my lines and connections to make sure they
are tight. I have noticed a small amount of diesel in the valley for a while. I sprayed some stuff and washed it out, vacuumed the rest and now can check for fresh leaks.
