My MD5A wont start...Had a leaky fuel line from the filter to the injector, and replaced it today...Also replaced the impeller and fuel filter. Bled the lines, poured a half can of diesel additive to my full tank of clean fuel, and even tried with a little ether. Nothing. Seems like she starts to kick a little with a couple ether sprays, then nothing. Any help would be appreciated! |

Was it starting and running OK before you replaced the fuel line? Sounds like you have not completely bled the lines. Keep trying until you see NO air bubbles at the injectors.
Forget the ether and try a squirt of WD-40. Is it cold there 40 or less? If so try a few squirts of engine oil in one cylinder, release the compression, crank the engine and drop the compression release on the cylinder with the oil.
Is your battery spinning the engine quickly?
Take two aspirin and call me in the morning. |

Update!
So, I found a rare and interesting problem...Yes, my engine was running, but it took quite a bit of starting fluid to start it every time, and sometimes it would die...So, I traced it to the fuel lines, and because I have a double Racor filter installed upstream, I disconnected the main line going from the Racor to the Engine...I used a suction pump to try and get fuel to the line, and nothing. I thought there was some sort of blockage, and kept looking everywhere. Then I thought it was not getting air to the fuel tank, still nothing. Everything was ok as it looked. Then, while in the engine compartment, I noticed on the bottom of the Racor filters, the labels for Inlet and Outlet fuel lines...Apparently someone before me hooked them up backwards! I couldn't believe it, especially since I was actually running the engine before. So, I connected everything the right way, and fuel of course came rushing out of the lines correctly. I then bled the lines, and am almost positive there is no more air in them. Now, I still can't start my damn engine! Thoughts??? |

If you crank the engine with your finger on the injector line, can you feel the injection moment? --> Probably no, so air is in the injection line and needs bleeding out.
Ease the union at the injector and crank over until fuel appears at the injector. Then crank until you can hear and feel injection - then try to start.
(Standard warning - make sure you don't inject high pressure fuel into your skin and bloodstream --> infection - this could happen if you remove injector and connect it up outside the engine to see if it sprays properly) |

Did you install new filters when you reversed the lines? If not you are putting bad stuff into the injector pump and injectors.If you have a safty screen on the pump that needs to be cleaned too. |
