It is difficult to say based on the information given. I'm assuming you're dealing with a 144 John Deere.

Are you 100% sure you had no air leaks and all your fittings were tight ?

You sure you got it bled properly ?

Was your fuel ok ? IE: If water in the fuel or bad fuel was part of the equation that led to a pump rebuild(as if 40 years of time isn't enough).

All those are possibilities, but if the pump isn't timed in, all bets are off.

I hate to be an jerk, but I'd retime. If you aren't sure, find someone who has done this on 144 and get them to walk you through it.

Be sure you have the fuel lines both open, as it sounds to me that you're starving for fuel. Also see that your throttle linkage is operating as it should. gregjo1948

well i was just outside working on the crawler ... it started it up.... it seems that only the first injector on the left side of the engine is spraying fuel... it looks like the fuel is trying to be pumped out from the injector pump... is there a way to set the pump ... when u first put it in.... can i turn the pump while it is running to see if that helps with pumping the fuel to the injectors ...

Sounds like it still needs to be bled.

is there a bleeder on the pump... when we bought the crawler it did not have the original fuel stage system... it has a single new filter the filter was just changed ... the fuel flows excellent to the pump ... it says in the manual to crack the injector nuts and let the air bleed out ... is there something else i need to do ... could i call somone to resolve this over the phone ...

Crawler has to running to bleed injectors, only way. Get it running again, and crack the injector line at the injector til you get fuel coming out. You will hear the difference as it starts to hit on that cylinder when you retighten the line.

Yeah I got it to run but it only sprays out of the first injector ...not the other three like it used to ..first injector I am referring to is the one closest to the radiator

Then, all things being equal, there is air in the other 3 lines, keep bleeding til they have all the air out. You must be getting something there, or it would not run, one cylinder is not enough.

What is a 144 john deere? gregjo1948

Post by **Lavoy** » Thu Oct 03, 2013 4:24 pm

Cubic inch displacement of the engine I believe he means.
