I just finished putting different head on an 84 300D and it won't start. No fuel seems to be getting into the injector lines? I have bled the fuel system a few times but fuel still does not appear to be passing out of the injection pump down the lines to the injectors at all. Am I missing something here ... ?I know I'm gettin' kinda' old and 'long of tooth' and eyesight's goin' but what the heck, over .....??

How are you confirming that no fuel is passing from the IP to the injectors?

cracked a line at top of the pump and cranked the motor ... nine spritzen or schpillin

Crank time?

Foot on floor during cranking?

Better to crack all lines at injectors, simultaneously.

Pull the vacuum line off the shut off valve, just to be sure nothing odd is happening in the ignition switch to keep vacuum on the valve.

If not too cold where the car is try prime starting it with wd 40 and it might pick itself up. If really cold there right now and car is in unheated space you might have jelled summer fuel .Especially if car has been off the road awhile to change the head. Forget the concept of jelled fuel I just looked up your address.

Cranked very long a couple of times and moderately long several more times. Was afraid of maybe fryin' the starter.

Funny but I can't remember about the foot on the floor either .... seems like I did but it'll have to wait til tomorrow when I try again.

Ok, so .... I should crack all lines down at the injectors and crank like hell, pedal to the metal and hope for some spritzing ...?? .... that what your suggesting, sir? If so I'll try it, thank you.

BTW, this block and IP had sat for a year or more in the car with the head off lines open ... but I did see couple drops of fuel at the output line junctions on IP during the assembly process ... 'twas a real Frankendiesel, was this beast. The head and injectors set on another block for a year or more, closed up though, before I took it off last week.

I confess to have given it a WD-40 shot also .... nine helpen

I will definately pull the shut-off hose off too .... good idea.

I really appreciate the suggestions too .... really ... thanks for the brainstormin' ...

You might want to drop the secondary filter to confirm that it's full of fuel.

And, if WD-40 won't light it off.........you might have larger issues. Try the WD-40 with two people.............one spraying and one cranking............

Ok .... I'll try all that stuff and try some of it more again. Would hate to have to think that I have it 180 deg. out of time or have the valve lash set too tight .... Will crank on tomorrow, weather permiting as I am outside on my slab .... thank you men very much. A humbling experience can these cars be at times ... great to have help though.

Both are possible..........but, neither will prevent fuel from being ejected from the IP. The engine might not want to start and run.........but, you'd have fuel.

You really need to follow the fuel...........where is it??

You have to crank that baby for a looooooooong time and make sure you have fuel coming out of the injector lines at the injector ends. The first time I helped a friend get one going after they had run out of fuel I was surprised at how much cranking time it took to get er going. Take your time and a long pause between starting times and the starter will be fine.

Thank you all very much again ... pretty comfortable I have the motor together right, thanks for reminding me to fucus on the fuel, Brian .... I know there is fuel up to the pump, I can see it in the lines cuz they're new, and also I checked; the spin-on filter is full. I'm hoping I simply have not cranked enough yet. I'd be OK with that

It's a wash out here in Temecula today ..... looks like not much chance of the weather co-operating this weekend .... sooooo ... time out !! .... will let everyone know what happens when I can play with it more.

Save the starter........try the WD-40 approach if you have a helper. Don't stop spraying even when you think it's running.............keep spraying for 30 seconds.

You guys have been helpful to the max and I'm hopin', with your continued help,that I will get to the bottom of this no-start issue soon .... UPDATE .. cranked and spritzed the WD like a madman earlier today ... I had first loosened all lines at the injectors, disconnected the fuel shut off vac hose. I also applied vac to the diaphram to see if I could feel anything moving .... couldn't swear if anything moved or not.

No fuel out of the injector lines at all. There was a little bit of fuel on the #5 injector but I attribute that to a seeping return plug.

I sprayed while an asssistant cranked without even a hint of a lick of a fire ....

I could understand a stuck fuel shut-off ..... but it should lite right off spraying wd directly into the turbo, right? There seems that maybe there two (or more) stoppages here .... Where should I go next ??
