She has fuel, she has spark and now and then she will go dududududududuudududududuBLAGHdududududududd when you try her but nothing more. Any ideas as I havent been in her for over a month now! :undecided:
-
sounds like your trying to start a turd :grin:

get the can of easy start on it :wink:

So no ideas anyone? :embarassed:

Engine turns but won't start
1)No fuel pressure;
Test the fuel pump and pre-pump and do a fuel pressure and volume test.
NEW FUEL PUMP FITTED
2)Jammed and/or sticking airflow sensor;
Remove the boot that goes to the intake and loosen the center line on fuel distributor.This will relieve
the control pressure.Press down on the center bolt of
the plate and you should feel no resistance or binding.Also check that the rest height and centering are correct.
DONE, RESISTANCE IS AS LITTLE AS EXPECTED
3)Auxillary valve is sticking;
NEW ISV FITTED
4)Defective cold start injector;
If the injector does not function,the air-fuel ratio will be lean,preventing easy start up.
INJECTOR FUNCTIONING
5)Shorted or defective thermo time switch;
The cold start injector will not work if the thermo
time switch is defective.Check this in the event that your cold start injector does not function before replacing.
6)Control plunger sticking;
Remove the fuel distributor from the airflow sensor and check to see if it moves freely.
7)Restricted injectors;
For this to be the cause,they would have to be severely restricted,which is why I listed it last.Do
an injector flow test and ensure that the delivery is
near equal.
FUEL IS GETTING THROUGH NO PROBLEM

So slight update, (my computer is in my garage hence a walkthrough of what i am doing) :grin: but, when I relieved the control pressure and then connected her all back up she almost started, any ideas?
-
Still no one with any ideas?

I've skim read what you've said.. Does fuel come out of each injector evenly? Does each plug have a healthy spark? Is compression similar on all cyl's (and high enough)? Its a turbo isn't it? If you have all of the above I'd be looking at anything else you've touched in the process of rebuilding it.. Everytime I have a prob I suspect the kjet, but it never is, its always something else, so I'd imagine if all you've done is remove it, then reinstate it I'd imagine nothings broken without being touched, unless you're convinced its a fuel issue as per pressure relief valve... Its hard to say without seeing it myself, and going through the basics. Timing is the main problem I get, when the cranks I've had have failed, and then a million different symtoms come along (including starting) that all stem back to the belt being 2-3 teeth out!
-
Well it was all working fine, until my starter motor fell out then she failed to start after a few 'bodged' starts.
-
Well go back to basics,starting with timing, working your way through everything. There's tests possible for every check you have to do, to indicate correct function or fault
-
Could the starter motor falling of caused timing to go haywire. As mkbal said I'd start with that first, I spent week trying to start mine and it was timing and coil in the end.

I dont see how that could happen though, surely the flywheel is bolted to the crank, in turn crank pully and thus cam pully and without the timing belt snapping nothing will have happened. There is no way it can be out!?
