Engine rebuild no spark???

As above my mate has done an engine rebuild on his classic, put engine back in today and it won't fire, it turns over but no spark! Changed cam and crank sensor but still nothing, we got fuel but no spark any ideas lads??

what ecu has he used ?

jap or uk ?

and what version is it ?

Not sure mate it's Swiss old car, it has a Prova ecu which I have told him to get shot off!

so am guessing he has rebuilt the bottomend and refitted engine ??

and used swisses orginal wiring ecu, etc etc

Yeah mate that's what he done, any ideas?

could be one ov many things..

best off checking all the wiring connectors

the big ones down near battery are prone too bending connectors or pushing out ov connector

He double checked all connectors but nothing, engine turns over but it's not sparking, there is power to the ht leads but it seems there no pulse?

has he plugged ecu check connectors in and see if ecu has any codes logged ?

He has checked for codes but Nothing came up?

hard too tell without havin car infront ov me mate

is fuel pump priming ?

if its not it could be a alarm/immoboliser problem

Yeah fuel pump is priming mate, if he has no joy would it be poss for you to take a look for him?

yeah ne bother mate

Are you about tomoro? He lives in woodstone village,

later on a will be, after 5pm mate

Check engine earths are clean and connected!

Getting spark from 2 packs abd other two are shite . Its getting fuel too. Hes tried map sensors ignitor pack ecu all from my uk turbo. Waitin to hear how he got on with my coil packs . Any other ideas lads. Earths and connectors all cleand and water free

crank sensor

Cam sensor...timing belt fitted correctly?

We have spark now on all 4 coils, still won't start! Compression checked and is fine, changed cam sensor, next thing to check is timing! Will keep use posted

make sure if ur trying different ecu's in that u change the cam and crank pinouts on the ecu.

as jap and uk are different.

Im sure hes back to the ecu that came with it now bud

Well we been on 3 hours tonite, timing spot on, spark on all 4, fuel ok, compression ok, but still won't start! We running out of ideas now! Any more ideas lads?

just mad question but the plug lesds are on the right sequence had this on me mates car a while back turned over wouldnt fire.
I went over to take a look found that his plug leads were in the wrong order i thought it would have fired and would just run lumpy put the order bak to the way it should have been and fired first time just a thought

baldys old car done this once.

and after a few hours a found it was the petrol in it.

but u have already replaced the petrol havent you ???

on baldys i had 2 totally empty the petrol tank, then remove all the plugs and clean them and then crank it over without the plugs in.

when a put it back togetha with new petrol it went 1st click.

wen a checked the petrol out a found it had traces ov water in it.

early classic ignition system(coilpacks) is pretty weak, ie its often the case that if its slightly flooded it wont start, take out all four plugs, crank the engine for 30 seconds with the crank sensor disconected, refiit plugs and it will be fine
