I am having issues getting fuel to the injectors, it seems to be trying somthing at the pump. I do know there is pressure at the port on the filters and runing the competitors electric pump.

I have just a an/jic to orb at the injector and get pressure relief when I cack it loose. It is just damp at the pump side of the line just cracking after a crank. I am gettting nothing to the injectors and have tryed many methods to get it blead. I have tryed cracked at cranking, then colsed with crack after crank cycle. The slinoids work as they shoud when comanded with power, fast idle is iffy.

Past me encripted some clues in this photo of the last awakening from slumber this engine has had year ago, it sat for years before that as well. The plunger on top right was stuck at the top and took some moving around to get it to spring, do know this is what the fuel shut off controls. Now needing to get this to flow fuel again.

Just hopes and dreams, olny got me many starting sessions off the other hafe some diesel kleen in a filter to hope a magick trick would work. It only got me 4 injectors trying to get wet and seen like it was working like this. So I became desperate and grab some acetone from the paint project to half fill the front filter with, found a small bit of a green slime tho. Did get bio kleen to deal with it as well, unsure if should let the pump run for s bit to mix everthing? These past few runs on the starter have given good results now, it is ether dribling or spitting now. So might be getting close to starting this beast,

Well its trying to start today but is still putting up a fight, will keep trying. It will fire off a few times then die, if I try again right away it turns like a sewing machine but will fire again if weight 30min. She needs to appreciate what I have done for her and wake up.

Sorry about the rambling under frustration from the situation. let me try to make this thread a little more user friendly by adding a vidio of the current atempt to start. The first few days where of me trying to start this with a filter of diesel kleen and yesterday did a filter of acetone. The first try was not getting fuel to flow through the injection pump, so got desperat with the acetone. Found algae in the filter when last pulled, so also added bio kleen to the tank. Now it is flowing fuel but is not lighting off for very long.

Doesn't sound very happy for sure.

Holding the throttle fully open may help. I've always done that whenever I have to bleed air and it seems to make a difference.

Odd that it doesn't even sound like it's trying while it's turning over though.

I have mostly been doing this holding the throttle open, spring is off so will stay open. Is there a way to tell if this 7 year old fuel is bad? Soaking a peice of paper in fuel will light easily on fire.

Well things get worse, this time it just kept spinning like a sewing machine even after runing glow again. In its coruse of action it blow out a oil filter oring, so there is something up with the oil cooler. Would high oil pressure keep it from starting?

I can't answer that because I have no clue. I've heard of people using older diesel without issue though.

I don't believe there's any connection between the oil pressure and the fuel system at all, so I can't think of any way that could have anything to do with it.

The sewing machine sound is generally no compression if correct and hear it a lot on vehicles with a broken timming belt/chain. Aren't hydraulic lifters ment to maintain a bit of compression, so that makes me wounder if Im getting valve float from the high pressure. That is why Im thinking it ties together but may be over thinking this new problem on the table.

Got it to light off but pulled throttle closed to far and killed it. So need to come to a conclusion why it keep going into sewing machine mode that keeps it from starting.

Got the cooler back out and cleaned up the pressure relife, it was stuck and should had payed attention to this before reassembly.

Now a massive clean up is needed at aisle 13

Now fire in the hole and partial run

Valve float happens when the springs aren't able to return the valve to the seat fast enough at high RPM. That should not be an issue with starting. You might want to check and make sure that all your valves are properly seating though because that could cause a lack of compression.

It seems that high oil pressure can lock up lifters and also cause valve float, Im finding around 90 psi is where a filter o-ring blows out. After fixing the pressure relife, it has not been giving failed starts followed by the sewing machine sound on next crank. I have had the engine running around 10hrs off and on flushing the cooling system without any issues starting, do have to floor it to start cold. There dose seem to be some other issues, like low to mid throttle being unreponsive cold someimes and random hunting off idle. All that seems to be clearing up slowly but dose seem to have issues maintaining idle going under load, it will die cold but warm it might survive where will return to idle. I have hydroboost and this video is showing what it dose standing on the brakes, not too much issues moving the truck a short distance. Steering will do the same if I take it close to lock.
