detroit 60 starting issues 98 interntl

Well u guys were right .... the check valve was bad, i could blow through both sides... but , didnt fix my problem. So now im searching for another leak which im thinkin injector o rings??? Except they were just replaced. I was told something about a solenoid that can cause similar issue?

Im pissed with this mechanic. I had specifically asked him to run a pressure test , he never did... replaced the check valve and sent me on my way. It was still rough starting but he mentioned air in system needs to bleed out. Then it will start fine.. and here i am same issue $340 labor $110 check valve. He spent most time rechecking the stuff he did last time, fuel pump and fuel lines. If i can find these other possibilities i think i will tackle them myself with ur help gentlemen. Thnx and have a great day..

 

I dont have one of those fuel filters... tank vents? Im assuming they have some kind of floater on top of the tank with the hose sticking out??? I will check that today. Solenoid?? I might have misunderstood him when he was telling me about the injector o rings... so if a solenoid in engine doesnt ring a bell to u, i must have it wrong. Thnx alot for the info ... i will get to it today and post back what i find. I need to get back on the road today tomoro at latest. Have a great day...

 

No sir i dont have any codes thrown and SRS light... hmm im not at my truck now but when i get in there i should be able to tell u. But gauges look normal and crank speed should be good. My batteries are brand new and starter is good and consistent. I will check that valve you guys mention. There is a brass fitting that plugs ontop of the fuel filter on top. Looks like a quick disconnect fitting with nothing plugged onto it.
While truck is running i did notice small bubbles inside tanks..
Injector tips sounds like a possibility...
I will continue troubleshooting and hook up a gauge to fuel sender port and reread your responses to make sure i didnt miss anything. Thnx fellas i will report back in a few

 

Well.... pulled the exhaust manifold off with the help of a friend and turns out 3 exhaust ports are constantly wet of diesel. Stared the engine and those 3 ports shoot out. Lots of smoke. Which leads me to beleive that thos injectors are bad and are sticking open. Or im assuming that i cant rule out the head just yet?? Head was rebuilt with engine. When engine was rebuilt, i didnt push for having all injectors rebulit instead of just the 2 that were bad. I didnt even think about it. Had the mechanic brought it up i would have definately gon.e for it. We will pull off the injectors today and install some rebuilt ones and see what she does.

 

Installed six tester injectors and problem solved..

this is just a FYI... while the engine was apart being rebuilt, the mechanic had the injectors just sitting out in the open for weeks.. 2 injectors were rebuilt and 4 were reinstalled. The truck turned out to have 4 bad injectors which no brainer would be the ones sitting out to dry. I had brought that up to the mechanic when i saw them sitting in the sun and he said..... awww theyll be ok. Go figure those four turn out bad 30,000 mi later. Because of this issue that could have been prevented or atleast prolonged now i put so much stress on my starter and brand spankn new interstate batteries. I am really startn to see why so many new owner ops dont last very long. I should be up and running by tomoro a.m. thnx fellas
