If you look at the engine and follow the fuel line to the first thing it comes to. That's a filter, then a pump.
loosen the fuel line connection after the pump and kick it over (no flames, and use a small bucket to catch it) until you get only fuel. retighten fuel connection and start it up preferably by removing air filter and using "Start Ya Bastard" down the throat. Not yours tho.
Should be fine from there.

most diesels have a lift pump next to the injector pump.you unscrew the cap and pull it up and pump it up and down until it buils up pressure and it should start.

in the senter of the fuil pump you will see a littal screw undo that then pump the fuil pump un till the fuil comes out the screw it back.

then crack No 1 and 3 injector. turn the engine over and give it full gas untill the fuil come out.

then engine will try to start if the fuil starts to come out of the cracked injectors with full gas do the in jectors up then it will star.

when it dos keep it going on a fast tick over for a minit or 2 then you have bled your engine

all the best of luck hope that will help

 removing air filter and using "Start Ya Bastard" down the throat.

DO NOT USE EASY START ON YOUR ENGINE IT CAN DAMAGE IT.

Motor will run with the fuel injection pump dry, the pump needs fuel in it to lubricate itself.
I don't think the ether (whats in start ya bastard ) itself will damage the motor if its used sparingly. We used to use it on an old diesel where the motor was too flogged to start from cold as it couldn't  generate the heat to ignite the diesel. It would start fine once warm.

cant see how that would damage the pump,
like it would be full n pumping within 30 seconds after starting wouldnt it. and would have residue of diesel in thereto lube for that time.
not like it would be running for 30mins without diesel in there to lube.

Would you run your engine without oil in the sump for that long?  I understand what your saying about the residue fuel  but it only takes a small slither of metal to come off the cam or a plunger  in the injection pump to start major damage, why take the risk and run it dry for any period of time?

no, definatly not, but theres a big difference between an engine n a injector pump i think.
plus i thought we were talking about putting startyabastard down its throat after the injector pump had been primed???
but no worries.
so is that the only damage startyabastard does to a diesel engine?
stuffs the injector pump?
just thought id ask an expert, as i know nothing about diesel engines
and plan to have a few in the comming years.

LOL  I'm hardly an expert, I've worked as  drill rig fitter for a while so you could say I have played with  the insides of diesels more than most.

I've had the pleasure of  changing out a few injection pumps Presumably as a result of runniing out of fuel. Only seen it a few times so Unlikely I guess.

My interpretation of this thread was that the idea was using start ya bastard to run the engine until the fuel system primes up again so soz if I got that wrong.

fair enough,

yeah the most ive had 2 do with a diesel was to replace 1 liner ,piston n rings.
and relap all the valves in the head, new gaskets then put back together. 

ok so my question still stands
what does startyabastard do to a motor to stuff it.
any takers?

well that depends on wheather you are hitting it with a hammer at the same time ;D ;D ;D ;D ;D

 ;D ;D ;D ;D, ROFLMAO.
thanx waikatostocky i needed a good laugh,
ive seen that happen dont worry.

a mate of mine frank let his pisshead brother in law johny change the sparkplugs in his 115 hp johnson outboard, he crossthreaded 3 of them n tightened them up full. Aluminium heads.

anyway it was my mate that lost it and got a bigass sledge hammer and went beserk. the only thing salvagable was the S/S prop when he,d finished.

i recon its quite possible of dying from laughing,
far out if ever i nearly died laughing it was that day.

i also felt really sorry for frank 2. poor buga.
i would have been chasing johny trying to hit him with the hammer.
