no spark on the c20let

[napalm_27]

just read that it could be the fuel pump realy
iv had to bypass my relay as it isnt working properly
could this be the reason why im getting no live to the coil..?
if so anyone got a spare relay thats close and could drop it to me like now or tomorrow :thumb:

[Adam]

It wont be effecting the coil.

DOes the ecu light come on with ignition?

[napalm_27]

nope tried that a min ago its like there isnt a live to it
i pulled the ign. live throught the loom and have put it to the one on the nova loom
but nothing
even swapped bulbs about
i no the live on the nova is working as i put the pump to it and it buzzes away like it should

[Adam]

But is it staying live when you crank the engine?

[napalm_27]

cant hear the pump when its cranking over so cant say really
do you think its the ign. live dieing once its cranking over..?

[Adam]

Some ignition lives die when you crank.

Where have you wired it to?

Put a multimeter on it, or a bulb and see what happens when you crank.

[napalm_27]

done it to the bottom ignition live on the black box
did it with the xe in my old nova
may it be that.??
can go change it if it is
just want it to fire up so i can finish the rest of it off

[let_nova]

you connected the switched live?

[napalm_27]

black wire over the gear box you mean..?
i.e ignition live
yes thats the one i pulled back through the loom and connected to the black box

[Adam]

That should be fine then.

DOes it turn over fine? (nice and quick?)

[let_nova]

earths all ok?

[napalm_27]

spins over lovely
got earth for gearbox and earth from alternator bracket to battery there all ok and good no issues there
this is whats bugging me as everythink is/looks ok wiring wise
its just there is no power to the coil
i spoke to nobby and sloth on the phone earlier
sloth said about putting a ht lead straight on the coil with a plug in it to see if theres any power to the coil
and there wasnt no spark
the plug for it is abit broken but still is on there nicely
iv got all the wires connected that should be
thing is it run in nobby's ok
and literally all we did was take it out of his and put it in mine
so cant see what is wrong with it
anyone fancy coming to give me a hand lol
other wise i can see it ending up in 2 pieces and on fire like the cavalier and the astra coupe lol

[Andy]

The alt earth doesnt go to the battery,theres a strap going from the alt bracket to inlet manfold if its the same as an Xe
Have you wired up an ecu light on your clocks? Its a Brown/blue trace

[napalm_27]

no you've miss-understood i just put the battery earth to the alternator bracket just so it is earthed as i lost my proper nova one and im using the one that was left on the f28 gear box so its not long enough to go anywere else really

[Andy]

ah right,so have you an ecu light wired up? if not do it next

[napalm_27]

yer got it to the yellow/brown (iirc thats the one) but its to the right one
but no light is coming on
im in two minds to whether the ecu is getting any power or not
as i would have thought it would be on if it was powered
just really tedious that it sitting there spinning but no firing
really could do with an extrta pair of eyes to give me a hand
as im trying to do everything on my own
and trying to turn the car over and look and the plugs is a proper chore lol

[Andy]

put some pics up of whats wired to what Nathan ie the fuel pump relay etc

[napalm_27]

i would mate but my phone went on a spastic one over heated and now the battery is dead :(
but got everything wired properly to each wire using bullet connectors
(due to knowing what wiring is like and how much of a pain in the **** it is)
the only thing that i think may be the reason is the ign. live for that has to be wired up
i tried putting it to the battery to see what happened but still nothing
no spark no light no broom broom :(

[napalm_27]

anyone else got any ideas.?

[Sloth]

crank sensor, my 2.0 8v is doing exactly the same, and im getting no pulse feed from the sensor. i will take some pics of how i tested it earlier....

[napalm_27]

yer tried everything you said earlier buddy
rewired the ign. live after pulling it back through the loom
the fuel relay isnt doing anything
theres no eml light
and theres no spark
wouldnt have thought it would have done that from just going from one running car to another car :confused:

[Sloth]

mine has. id try another one...

[napalm_27]

but why would there be no eml light on..?
its wired up and i even changed a working bulb into the eml and choke light hole and still nothing

[Andy]

Which wire have you used for the eml? (off the LET loom)

[napalm_27]

ermm the brown/blue wire i think it is or the brown/yellow one cant remember off the top of my head

[Andy]

Well it should be the brown/blue.Make sure.

[burgo]

i
but got everything wired properly to each wire using bullet connectors
AKA not properly. the only true proper way is soldered and heat shink. so i would surgest checking all your wiring before going any further

[napalm_27]

think its the brown blue to the brown yellow on the clocks as its a 1.4sr
think thats how it is iirc

[napalm_27]

AKA not properly. the only true proper way is soldered and heat shink. so i would surgest checking all your wiring before going any further

i only wired up the ones in the actually car i.e nova to engine loom and they are all fine
and im not soldering them jst yet as it will make it difficult if i need to move/change place of any wires that why iv used bullet connectors atm
i will be soldering them all up properly once i now for certain i dont need to mess about with them no more :thumb:

[burgo]

your really not that confident with your own skills are you lol. temporarily connecting everything just incase

[napalm_27]

your really not that confident with your own skills are you lol. temporarily connecting everything just incase

i asked for help not critisism
i dont own a soldering iron so i cant solder anything till i can borrow one off my mate anyway so for the time being it will do
i just need to be pointed into the right direction of what the problem may be

its like there isnt any power to the ecu/coil
so it must be a ign. live problem but if anyone else has a good idea of what it could be then would be nice to see what you think :thumb:

[napalm_27]

anyone else got some useful things that may help me solve the problem..?

[Sloth]

ok. undo your ecu plug, undo the silver screw and the 2 smaller brass ones. the central part with the pins will now prise out. if you look at the side where all the wires go in, there are pin numbers at the edge, your looking for pin 28. its a black wire in the middle row. if you have 12v at this with the ign switched on or cranking, the wiring is ok, if not its your ign live to the ecu. also check pin 18, a large red in the first row. i will take pics tomorrow.if all this is ok, its a sensor issue, as the ecu will be powering up ok, or the ecu will be goosed.

[napalm_27]

ok mate cheers
its apparently ruuning phase 2 chips
it was all working in nobby's so dont see why not in mine

[Sloth]

not sure, but stuff can be affected by being moved.

[let_nova]

sure can, bought an engine that was running fine in the car, fitted it to corsa and the starter was goosed lol

[John]

ok mate cheers
its apparently ruuning phase 2 chips
it was all working in nobby's so dont see why not in mine

You're missing something mega simple then, have you asked nobby how he had it wired?

[burgo]

ok mate cheers
its apparently ruuning phase 2 chips
it was all working in nobby's so dont see why not in minehow about it was involved in a serious accident, wires could have so easily got shorted out and fried something

[Sloth]

thats what i was getting at /\

best advice im gonna give is, get nobby down to look at it.

[napalm_27]

nobby is like 2 hours away lol
if all else fails il just buy a new loom and ecu
and start again with the wiring

[napalm_27]

well dom came down today with his mk1 astra c20let (i cum in my pants!) and we tried every thing we all could think of
swapped the coil's over from the astra to the nova
tested the nova one on the astra
and also tested the ecu from the nova on the astra
everything is fine
so we suspect the loom is buggered some were
as its like there isnt a live getting anywere atall
so going to try source a new loom thats not been cut with a decent length of loom left with the 3 plugs so i can make a plug and play loom up
so if anyone knows of a loom going or has one drop me a pm :thumb:

[Andy]

make a live up then to test,test all your lives

[napalm_27]

just going to buy a new loom cba to mess about testing all the lives etc
we were at it all day trying different things but with no avail

[Sloth]

wanna sell your old loom?

[napalm_27]

name a price

[craig green]

yer got it to the yellow/brown (iirc thats the one) but its to the right one
but no light is coming on
im in two minds to whether the ecu is getting any power or not
as i would have thought it would be on if it was powered


If the ECU is not getting any power, the EML will not appear at all. It should glow when ign is turned on. :thumb:

[napalm_27]

yer we figured that one out today
going to get a new loom mate

[Sloth]

considering its moosed, £20 posted?

[napalm_27]

no
not worth my time wil cost me near on that to post it and package it

[napalm_27]

right after my stupidity
iv connected the live feed up and now have eml/choke light and power to the relay ecu etc
but still no starting
iv snapped the end of the king led but boged it on to try get it to fire but thats not happening
i put a plug lead on the coil with a plug in and got a faint spark and a big jolt up my arm so there must be some sort of power getting to it
but not any spark as such
iv got 2 set of leads coming (8mm blue ones and champion set)
so il try them when they come but anyone got any idea what it could be..?

[Sloth]

so you now have a spark at the coil? in that case fit your new leads and see what she does.

[napalm_27]

well i did yer but now cant get one again :(
just dont know whats up with the blady thing
going to have a proper go at it tomorrow
see if i can get her to fire up

[Sloth]

ok, so big red live is on, small black is on, and the fuel pump is running. are you getting a crank sensor signal?

[napalm_27]

no fooking idea mate

[napalm_27]

well tried a crank sensor off auzzy's nova and no joy with that either so have no idea what it can be now
starting to get really pissed off with it
