    I have a 2006 TL140 and it has a heck of a time starting, even just after shutting it down too. Compression, glow plugs, engine timing, lift pump, fuel filter, inj pump screen, fuel line from tank, and return line to tank are all in good condition. Once it's up and running it runs great, no lack of power. Takeuchi part number I1-13260-0011 is what I'm wondering if there should be some sort of a spring loaded check valve. Mine just has a little hole through the center allowing fuel to freely run back to the tank through the return line out of the inj pump. Or my inj pump may need rebuilt. Thanks. -Kevin

    The part I'm referring to is the return line valve/fitting, number 212.

    More than likely your fuel stop solenoid is not locking in all the way when cranking .One wire will pull in ,other will be hold ,third will be ground .
    What is you email address I can email you the manual

    Thank you tool_king. I forgot to mention the solenoid. I checked it too. It is cycling fully one way when key off and fully traveling other direction with key on. Stop to stop on injection pump stops. Thanks for offering the manual. I have a copy of it on my computer which has helped me out tremendously with this machine. Just still having a (what I think) is air getting into the pump. I replaced one injector which was spraying a weak pattern. Others popped at pressure with good atomization.

    Hi Willard, What Toolking is saying to check is make sure the solenoid is staying open when you are actually cranking the motor.

    Ahhh, okay. Yes that is a good point. I guess I never did check it while cranking the engine. Might be loosing enough power or weak solenoid that it is partially closing the shut off valve. Okay I'll defiantly check that. Thanks Ronsii.

    You can have one that will work but when crankin the the magnet is weak to hold it .Also make sure you have proper voltage and grounds .because those can mess you up big time .

    Okay, I opened the cab and turned the key on. Solenoid opened fuel shutoff valve. I cranked on the engine with nothing but sputtering, normal grey/black smoke coming out of exhaust. I made sure shut off lever was in the fully open/run position and held the rod in the open/run position while cranking, with no change in engine sound. It's strange how much smoke it can produce making it sound like timing is an issue. But it's timed correct. Sometimes it will start right up with half throttle other times it will sputter and sputter with taking 15 seconds to start up and run on its own.

    I've had engines with a bad glow plug relay cause hard starting... especially with motors that need glow plugs to start.. also this can be an intermittent problem when the relay first starts to go... but after a while it burns out the contacts completely in the relay.

    Okay. While doing a compression test, I checked and 2 of the 4 glow plugs were bad so I replaced them. (Those things are expensive!) If I glow plug the engine before starting it does tend to start a little easier. It still sounds like after changing a fuel filter upon restarting. But with a direct inject engine on a 85° day, it shouldn't need glow plugged unless the engine is wore out (low compression). I'm getting a solid 11v to the plugs 3 or 4 times when i tested that circuit in the shop.

    Did you check the banjo bolt that goes thru 189 in your breakdown?? fuel inlet to the supply pump.

    Yes I did. There is a little plastic screen in there that had some gunk on it. I cleaned it off and installed new copper crush washers in place of the old rubber washers that were falling apart. Thanks for the reply.
