would like to say hi all! i have a slight problem, i have just got my son a micra s k11 and it will not start i have tried the following....

swapped the 2 green relays at the side of the battery ( no change )
checked the spark ( good )
took the fuel hose of to see if there is any fuel being sent when cranking over (good )
placed 12v direct to the fuel pump while cranking (not starting but pump is pumping)
checked the spark plugs for dampness as it may be over flooding these are dry and no smell of fuel when taken out.

could the problem be with the injector relay? if so where do i find this?

 

[frank]

any faultcodes or warning light jaxxplay ?

 

[jaxxplay]

i have had a mechanic plug in the diagnostics and no fault codes found? i have cleaned 3 earth connections around the engine, we put some brake cleaner on cranking the engine over and i starts but then dies as no fuel is getting to the block through the injectors, we have checked all fuses and there good, swapped over the blue front relays at the side of the battery,

there is a blue relay at the top of the inside fuse box is this the injector relay?

 

[frank]

is there a 12v feed to the injectors ? and what year k11 ?

 

[jaxxplay]

thx for replying, nothing going to the injectors, its a 2001 plate

 

[frank]

the injector fuse is notorious for rusting, and they are live fed and signaled via earth

 

[jaxxplay]

is this the small 15 in the fusebox? sorry if i sound dim...lol

its near the battery on a pre-facelift, but i dont know where yours is tbh

 

[jaxxplay]

ok i have checked all the fuses and they are all good i double checked the 12v feed to the injectors and nothing still seems as though the ecu ( has the black connection port) in not grounding the injectors would this be right?

 

[frank]

the download pdf manual on here shows how you can turn the dizzy and listen to the injectors click (i tried it the other day, and they do click quite loud )

 

[jaxxplay]

no dizzy its this engine!

 

[jaxxplay]

thanks for all the help frank you seem to be the only member...lol

 

[frank]

ahh yeh, does it fire up with a drop of fuel down the throttlebody ?

 

[jaxxplay]

yep and then dies

 

[frank]

the immobiliser cuts the injector signals, hopefully its not that

 

[Enuo]

Have you got a multimeter and a friend?

 

[jaxxplay]

the red light goes off when the key is in the ignition?

 

[jaxxplay]

yep im very gifted and have both of them..lol

 

[Enuo]

Pull a plug from one of the injectors, stick the multimeter on the pins and get friend to crank the engine, see if you can see any voltage

 

[jaxxplay]

no voltage kaaaaaput.

 

[Enuo]

There will only be voltage for a split second, so even if the injectors were getting voltage you might not see it as the refresh rate on cheap and even some fairly expensive multimeters is pretty poor tbh, you'd need an oscilliscope to see properly. It would have just ruled out immobiloser of you'd seen voltage is all...

 

[Agent_Sm1th]

I have an immobiliser and ecu for your car if you require one.

 

[frank]

I just tried a 12v led, and it lights it up ok

 

[Enuo]

I'll rember that, sometimes the oldschool methods are best eh

 

[jaxxplay]

nope tried volt meter a LED also fuse tester (pencil light thingymajiggy).

a nats issue should flag a faultcode eh but if its a generic codereader it may not show

 

[jaxxplay]

really scratching my head with this one, feel like to just get rid but its a nice little car.

 

[Enuo]

Shame its a coilpack, cpuld have stuck a non nats ecu in to test

 

[jaxxplay]

just a thought would a bad crank sensor not allow the ecu to ground so the injectors will work.?
