M1009 startup then "stall out" Hard 2nd start then OK

part #

When you get that fixed.. make sure to share the part number..

I backed in my driveway.. so the nose was downhill...

Perfect start up!

But I can see seepage from the fuel filter area..

Filter was changed in 2010... I'm gonna try another filter..and replace the rubber fuel lines going to the assembly.. They look kinda crappy.

If that dont solve it.. SPIN on here I come...

My truck only does this if i do not press on the accelerator when it starts.

According or Operators manual and sign on sun shade you should press the pedal half way down when starting.

Having this same issue even after spin-on filter install

Hi all,

I installed the Wix 24770 filter base and spin-on filter, changed rubber hoses to and from filter, and the return line on the IP. I have an '86 M1009, which appears to have the updated check valve (no glass ball).

I'm replying to this thread because I had expected the spin-on install to fix this issue (just as described... starts instantly, runs for 3 seconds. Dies. Cranks for 7 seconds before reluctantly starting, then acts weird (idling unevenly, surging, etc) for another minute before finally settling down and running normally.

I have an electric pump I'm planning to install soon... maybe this will help. But in the meantime if any of y'all have any ideas.. Thanks

I also just replaced my fuel filter with a spin on and am having the same no air in return line: start.. die... hard to start... now lots of air in the return line (I swapped in a clear line)... I guess its time to check the glass ball check valve?

I posted a similar problem on my 1028. Hard starts, then would run fine.Turned out it was a 3/8ths fuel line from the fuel tank that rubbed on crossmember and wore through a tiny pinhole in the line. Cut line and spliced in rubber line. Problem gone. Check your fuel lines - ALL lines from tank to IP,rubber and rigid.

I pulled the check valve off the top of the IP off and blasted it out with some non clorinated brake cleaner... it would let the cleaner out one way, but not the other, so it seemed it was working properly.. but when I looked through it i could see a fracture in the glass ball.

I pulled one off an old IP ShadeTree pulled out of a junker... it looked good so I swapped it in. I let the truck sit about 15 hrs (until I had to drive to work this morning). I Had a hard initial start this morning, but then it fired... so the symptoms have changed some but not a lot... I can't remember if I fired it up after I swapped the check valve.. I think I did... anyways....

I'm suspecting I've got an airleak in my injectors... but to be sure I guess I'll need to check every inch of fuel line, or pressurize the fuel lines like the Haynes Tech manual suggests...
