TD - it is not even firing on ether.....sounds like more of a timing or compression issue....no?

That is where I'm leaning to myself but want to rule out all possibilites that could mask what is going on, I've got to go out to the locomotive shop end of year production has been a bear this year.

EPA has mandated the new emissions requirements for Diesel locomotives come in midnite 12-31-09 any Diesel engine in my shops inventory not installed and running by then, becomes a boat anchor, I've got (3) $300 k potential boat anchors I'm worring over, pls 6 more already started that have to be finished as well, I'll check in later.

Did not mean to digress LMS I just wanted to let you know why I was ducking out on you.
 
I would try to put some fuel into the intake. I went through all that with my truck. It still runs to this date. Like i said it took me alot of fooling around and it was as simple as just dumping some fuel in. Try that and go from there.
 
Can anyone tell me where the theft deterrent device is located? I cannot find it on the schematics I have ... truck does have keyless entry, But I am not aware of any device. We did a tear down & found the woodruff key on the Cam sheared ... just the 3/16" driving the pump gear. put everything right & triple checked ... Still have a no start ... Fuel at injectors even with the optical sensor unplugged so that problem solved. Fuel solenoid straight up .. Tried a shot of fuel in the manifold & starting fluid (glow plus disabled) White smoke with ether but no black smoke. The truck has been sitting since last April ... at this point we are pretty sure the timing is right, the fuel is new & definitely there, The electrical checks out, the fuel solenoids open...... So, unless the PCM can somehow disable the pump ?????????????????????? Thanks John B

X2 it should hit on ether. With the damage to the timing keys etc. I am thinking you bent some valves. The can just eliminates the complete fuel system if fuel in the intake goes out the exhaust unburned. :eek:
 
Ok on X3 ... Both the pump & the PMD are new (PMDfrom diesel Care) The Grounds have all been re-done with new ends & checked with Ohmmeter ... IP has 2 grounds. Proper voltages to Fuel solenoid, PMD & to IP solenoid ... Harness 15 pin connector is clean as are the connections on the PCM ... The engine was never out of time however the pump definitely was. With ether it will or tries to fire on one cylinder ... & will almost stop when it gets too much on a compression stroke ... White smoke, a little black ... Could we have injectors stuck from sitting so long?
 
If it doesn't run on ether, the timing is out of whack or there is not enough compression to cause ignition....

Injectors have nothing to do with the engine not firing on ether....
 
Thats what it sounds like but there is pretty much no way to mess up installing a new key. As to the lack of Compression, You could be right but this truck never burned oil & did not exhibit any of the signs of engine wear connected with low compression when the IP quit.
Compression check next on the list though ... Thanks JB

I believe there are two ECM fuses in the under the hood fuse box, are they both good? One of these fuses burn and the ECM can't control anything.
 
I recall the 5.7L Olds diesels would shatter a cylinder liner or blow head gaskets on a regular basis when the IP got dirt in them jammed up and over advanced for just one injection cycle. So the sheared key could have mistimed the pump for a couple of cycles...

Sounds like severe internal damage with one surviving cylinder. Maybe busted the crank? Only other thing I can think of not firing on ether is a slow cranking or bad starter/wires/battery type issue.
 
Not sure what the cranking speed to light on ether, maybe less, but on fuel you need a min of 100 RPM cold to fire.

If it's cranking like are...are...are...it ain't going...

I never see in the previous where cranking speed is mentioned, maybe it was...
 
This is becoming a real mind boggler ..you guys are right, The injection system would have nothing to do with firing on ether ..... Unless I'm not using enough ether or there is internal damage in the engine .... The thing is it was running quiet & smooth when the pump quit just before I reached home ... I re-started it made it home & it idled for a couple of seconds & died ... I would have noticed a broken crank when changing the Camshaft key. I would think there would be a distinctive noise with piston or other internal damage & it would have to happen while cranking ..... just a thought here we are using ether that came from Wallmart ....no doubt from China .... a very thin thread of hope but still??
 
The Cranking speed is right at 300 rpm .....cleaned up starter & solenoid connections & rewired ..... new Interstate HD Batteries ...
A New Question here. No one around here has a Tech II OBD reader except for the Chevrolet Dealer who currently has no diesel guy & wants 300.00 just to tell me the codes if I get it there ... Is there another OBD reader that will give me any help in the cranking mode?? Thanks JB
 
X4 on no firing on ether sounds mechanical to me.

Good possibility engine sat around for awhile leads to the bores drying out somewhat. Try to start using ether repeatedly and now you may well of washed away whatever oil is left therefore naff all compression. Problem with ether is that you can create a vicious circle and exacerbate the problem. I've seem more than once an engine loose ring seat in a very short period of time due to a fair amount of ether.

First thing I'd do before you go any more crazy chasing electrical is get some oil in the bores and wet them up to counteract the ether use. Moreover as others have said compression check. Even with crappy injectors if you are getting fuel and have compression with a sniff of ether she should clack.
 
Cant answer your questions directly re location & disabling ,but you might try a google search on theft deterrent for 6.5 diesel lots of info for relearns . See also faqs at Diesel place .
 
The theft deterrant is the least of your problems...

If you spray in ether, and the engine is rotating (engaging the starter), the engine will fire up regardless of your IP, injectors, electronics, etc.

This is starting to sound like a broken record....test the compression!
