83 6.2 ran dry need help priming
 

Hey there , Just as the title says , 83 ran dry . I found a cracked line and I must of hit it or did something and low and behold before I touched it it ran dry . Well while it is dry I changed the filter and refilled the filter with clean fuel , Now I cant get it to start . Any Ideas on how to prime this would be awesome , thank you much .. Mike

Did you bleed the air out of the fuel lines? Have somebody turn the engine over while you crack open each line and bleed the air out. It may start just bleeding the line you replaced. You have to get the air out before it will run.

Agreed with above. Also, make sure you got power to both prongs on the injection pump.

Thank you for the suggestions, I will try messing with it today and see if that works.

BTW, if it's a manual, you won't be able to pull start it. I tried it once, and all it would do is stumble, until I bleed the lines.

Hey there :-) Manual it is , but now lays another problem, I got the system bled to the injector pump , and it still wont start so I am assuming until I am able to actually crack one of those lines that there is air that is stuck in there and not letting it flow from the injector pump ? Just out of curiosity is there a good tool to crack a line or assist in this , I cant break those lines lose, maybe a bunch of wd-40 ?

Another problem I ran across is my glow plugs are not cycling . I have no clue why they are not working , the solenoid has juice , I need a test light in a bad way , had mine last week and cant find it , but what would be some causes of the glow plugs not cycling , I know I pretty much well killed the starter I need to replace that and the solenoid would that have any effect ?

Yes they both could. Yeah you need a test light in a bad way. Are you getting juice out of the solenoid. I did away with the automatic one on my 6.2. If the stater is cranking slow it probably will not start the old 6.2 you have to kick em hard to get them to start.

Another thing I would do is do away with the mechanical pump and put a electric one on it so if you have to prime the fuel system you want have to crank it for ever and ever.

83 6.2 ran dry . glow plugs not working
 

Well I am going to pick up a test light tomarrow , I know yesterday when I finished messing with the truck the glow plugs and everything was functioning fine and today when I went to mess with it , the plugs wouldnt kick on not even the interior light , Im wondering if the solenoid is garbage , but It has power going to it , I tested it and know for a fact , and I unhooked the glow plug wires to the solinoid and I was able to open and close or turn on and off the solenoid jumping it with a wire . So I am wondering if something else isnt the problem.

1) more thing , Electric pump huh ? any recommendations, and here is a stupid question, but usually I try to leave well enough alone HAHAHAH Yea if I did that I wouldnt be in this mess , But if I did install a electric pump the mechanical just stays attached as it is right? Never added anything like that before.

The starter is garbage you can hear it begging for mercy when I try to start , not to mention the solenoid is sucking up the batterys when I try to turn it over 5-10 seconds at a time .

But I dont know where to turn , Starter needs to go but has enough kick to turn the motor, just drains the batteries so I cant sit and crank it with out resting it for a bit and giving the batteries a rest .

The glow plugs , What steps should I take to examine this problem ? what am I exactly looking for ? Why they are not cycling and where to start to examine this problem?

Also SInce there is fuel at the injection pump would there and could there be air from the injection pump to the engine stopping the fuel ? WHen I was cranking it today , I can smell the diesel exhaust burning some fuel , but shes just not kicking ...

The solenoid opening and closing does not mean power is flowing through it need a test light. That has a timer in it that may not be working or at some point may work to good add keep the plugs on and thats bad. I take them of and put a older ford style solenoid and a push button on the dash. As for the electric pump I have done it different ways. A generic fuel pump should work. Just cut the fuel line and put it on the frame. I have left the mechanical pump on them and just pumped through it or put the electric one on a switch and use it for a just in case. I would remove the factory one if it was me. You heave to make a block of plate for where the old one was its been awhile since I had one off make sure there is not a fuel pump rod in it if so remove it I think its run of the cam though its been awhile and put a hose between the in and the out of the old pump. Any way seems to work fine. If you get it started and never run it out of fuel it may be like you said leave well enough alone. I don't know how often you run the truck or what it is to you i just prefer the electric one. The stater spinning slow at all could be giving you problems it's not like a 350 if it turns just a little slow it may not start. You have to get it cranking fast enough to pop the injectors and its a idi engine which puts it in a hole to begin with. Are you sure the starters bad and not the batteries? How old are they?
There most likely air on the other side of the pump. Open some off the injector lines or all
of them if you can get to them at the injectors and crank it until a good amount of fuel comes out of them. Tighten them back up and try to start it.

Diesel running dry and glow plugs
 

Hey there thank you for the response, I am going to take a look and see if I can locate this mechanical pump if that is what is on there , your idea sounds better any ways with the electric. You wouldnt happen to know a good psi I need to run , I assume what ever the mechanical is running, but if you dont know I will do some research like I have been the last couple of days.

The batteries are a year at best , and I am pretty sure its the solenoid taking everything out of the batteries they never did this until I have been cranking and seen the starter sizzling I know the starter is draining and doing it . Well Let me check everything out and try cracking these darn lines again , I just couldnt do it yesterday so I will try today and I will let you know, thank everyone very much for there help !!
