2GM20F need to bleed injectors?

[rpeebles]

My 2GM20F ran out of fuel. I added fuel, the engine starts and idles for a bit but dies on acceleration into gear. The engine "dying" is as if it is starving for fuel, it limps then dies, not a sudden stopping. Then may restart and die again.

Do I need to bleed injectors? Or does it sound more like a clogged filter or bad fuel pump. The injector pump has recently been rebuilt.

Thanks, Roger

If you ran out of fuel, I would start by bleeding. Yanmars are usually pretty forgiving though. DO you have a Racor type filter you can see the fuel in? Did you by any chance pick up a bunch of muck off the bottom of the tank?

If the engine starts and idles, you do not have a bleed problem. If you ran the tank empty you likely pulled some sludge into the fuel pick-up tube in the tank and that may be partially obstructed and/or have fouled the fuel filter. I'd start with replacing the eliment in the fuel filter. It that doesn't solve the problem you'll need to clear the fuel pick-up tube. That can be done by "back-flushing" it to clear the blockage but the debris will remain in the tank. If that does work, you'll need a fuel polishing to get the debris out of the tank.

FWIW...

For the amount of time it takes I would run the engine then crack the injector fittings one at a time to see if there is any air in the lines and if not do what the others have mentioned.

Thanks all! Will try those things and report results back.
