i think im going to try checking my fuses are alright again.

[Brett]

Have you checked the AFM? if theres any sort of problem with that it will lead you on a merry dance :yes  
Check the BAC valve is operating on top of the UIM.

 If you have a spark and have fuel then your problem is most liekly going to be one of compression/sealing.  Id recommend running a premix and squirting oil into the chambers before you try it again.
 Make sure you\'re plugs are in good condition too, a dodgy set of plugs will give you all the problems you are having!

 If all else fails then give me a bell and we can have a natter over the phone.

plugs new, compression is good cos i know its a good engine before it was removed it started right on the button! i think its fuel - i dont know why i put that i could smell it cos now i cant. how can i get oil in the chamber without an oil can? afm i dont have a spare one - but surely if it was goosed then the ecu would just go into limp mode and still let me start?

if someone with a t2 could do us a fabour and check fuel hoses . i need to know which one from the fuel filter goes to the one on the right of the pipe going to the charcoal canister or if it goes underneath it?

G i read that thread he has the same problem as me - i did a search and the same suggestions get thrown in but i cant see any "i fixed it, it was X causing the problem" posted. meh.

i was on that rx7club for a couple of hours today - all i could find was how to check stuff.. but some suggestions require an afternoon i guess. im still looking for a stupid mistake lol.

[Brett]

Hi Nas,

 Bear in mind, if the engien has been sitting then there will be no oil film around any of the seals, with no oil you essentially have very poor compression.  Can you get hold of a syringe or something similar?
 If the AFM is chucking out dogy signals then it can be impossible to start. (car seems to catch then dies, or just wont fire)

[FD3SNuttah]

haha a syringe no chance lol! Brett thanks for the suggestions - its just occured to me that i could improvise something - im going to use the funnel from a petrol can and pour oil down it that way im no doubt goign to get it everywhere! ill give it a go mate but without smellin raw fuel i think that it might not make a difference.

any more news matey ??

Stu

[FD3SNuttah]

yeh my mate shows up and spent two hours on it.
we double checked EVERY essential wire and they check out fine AFAWK

here is wat we assertained before rain and darkness stopped play

+12v coming from the ecu injector wires,. all rest of loom seems to be fine.
i got spark
it cranks
The fuel rail is pressurising
compression sounds good when being cranked (no exhaust after downpipe)
we find that theres simply NO FUEL going in. although the fuel rail is pressurised as when i undid the nut on the end of the top fuel rail a hiss and a spray of fuel came out.

now i need to ask you lot

is there anything state which would prevent the ecu from firing those injectors? - what you lot reckon i didnt disturb those wires as the engine came out with the loom still attached!

is there a check engine light? i dont see one light up is this going to be a factor.  as there is a wire on the the plug 1 going to the ecu which on the fsm is supposed to have a check wire coming from it but the pin on the plug is blank!

my netto multimeter isnt fast enough to see the momentary flips on the injector wires and theres voltage getting into the engine bay near the condensor. so hes going to bring a neolite (i think thats what its called) with him next time he comes round

i think hes confirmed my earlier view - injectors not flipping whats my next step?

[Brett]

Take out the injectors and check them, make sure that they are switching and make sure they are not clogged.  Its going to mean removing the UIM and IC, but probably worth it!

[FD3SNuttah]

yeh i was going to mention that if it was flooding and fuel was going into the chamber then i would smell it coming out of the downpipe - we was cranking that engine like a good un - purposefully trying to flood it - but couldnt smell that petty.

[FD3SNuttah]

i was afraid you would say that brett - is there no way i can get to an injector and then hot wire it? i couldnt see the primarys only one top one that UIM looks like a right basterd to take off.

Does the car have an imobiliser??   I went to help a friend who had done a head gasket on a diesel renault clio only last week, he had spent a whole day trying to get it started, as soon as I got there I pressed the button on the key to lock and unlock the car and it started first time.  i was not popular for a few minutes.   you did say it started once, so what has changed since then??  just a thought.

[FD3SNuttah]

no immobiliser  - lol not that easy this oen mate haha although i wish it was
