M1028 fuel problems??

[uscgmatt]

I picked up a cheap 1028 the other day that hasent been started in a year or two. I've changed the fuel, bled the system to the filter, and cleaned the governor housing on the ip (it was lets just say nasty). After a bunch of cranking the ip fills with fuel but nothing to the injectors. I have even disconnected the GPs and used starting fluid and nothing. I think it is the ip but want some expert opinions before I dump alot of cash on a new one if I dont need to. Thanks for the help.

There is a wire going to the IP, check for 12v when the ignition is on. Or listen for a click when you turn on the ignition.

It has 12v on it. And when i had it open I tested the solenoid and it worked. The linkages it connects to are really loose, I dont know if it is normal or just worn out. Thanks

it sounds like your shutoff solenoid is bad, or there is a bunch of crap in the ip. depending what you paid for the truck, it may be worth it to just pull the ip and have it checked out.

If it won't even fire on ether there are other issues

Could it be the timing chain? since it connects the IP and controls the valves if it is broken then the ip won't turn and valves wont open. Is there an easy way to check?

 

[CCATLETT1984]

the camshaft in a 6.2 is gear driven off the crank, then a roller chain drives the IP. When you say it wont start off of ether, do you mean it wont fire? or that it wont stay running. The complete lack of fuel at the injectors points to an issue with the IP, you can see the chain if you look down the oil file tube on the front of the engine.

It doesnt even sputter with starting fluid. With the ip removed and turning it counter clockwise it moves kinda freely with certain points being harder than others (building pressure maybe). I will check what I can see with the chain. Thanks again

to get it to sputter off of ether, you must have the glow plugs threaded into the engine, not hooked up. otherwise its not going to build any pressure in the cylinders.
