Conversion wont start?

[eddo]

Hey, ive got my conversion all wired up now (rev 3 engine in rev 1)

It turns over fine, it sparks and fuel gets to the rail as I took the return off.

But for some reason it wont start

Ive got this far, pleae help

Timing?

[eddo]

we slipped a new belt on the engine so it should be ok,

how do I check the timing is right?

cheers

Sounds daft... got enough petrol in ?? I know you've mentioned petrol coming through.. but if not pressurised correctly.. engine wont run... Go stick a gallon in it.. it'll fill the tanks swirl and pickup.

Do a compression check ( throttle wide open ) ....

ive slipped a bit more fuel in it, same problem

im pretty sure the new timing belt is on right as i marked it all up correctly when changing it.

anything else it could be?

Bridge the test terminals to see if theres an undelying sensor issue... TE1 and E1

If its firing... and fuels going in..... it should run.....

Pull a plug out to see if its damp from the fuel... fuel pump maybe running and it maybe firing.. but the injectors may not be switching....

Might even be flooded.. if you can see fuel on the tip of the spark plug, take a lighter to it.. and pull the other 3 out and leave it to air out a little...

You may have a hose not coupled up... open nozzle drawing in a large amount of air...creating a huge air leak... remember, the injector may fire and plugs maybe firing, but there needs to be that vaccum created by the pistons ( downward stroke ) to draw the fuel into the cylinders for it to all work.....

Ie... if the plugs are dry when you remove it.. drop a little fuel into the bore, then see if it'll fire...

Block the idle control valve channel.. you'll see a line from the air box, run up the side of the engine heading towards the underside of the throttle body... stick your finger over it....

Also.. is this a full rev 3 conversion ?? or is it a rev 3 engine with a rev 1 ecu / harness ??

Right its running for like 1 second now and then dying.

spark plugs look black but dry.

Power is going to the injectors.

Is there much chance that all of the injectors are busted


oh and its a full rev 3 car and engine loom.

ps, we havent got the alternator wired up yet but that should matter, right?

[JJ]

Normally unlikely, depends how long the engines been sitting.. but they shouldn't faulter...

Should still run without it connected up.....

Right its running for like 1 second now and then dying

Sounds like the ecu is shutting the engine down, have you done the error coded test yet ?? That'll generally point straight to it....

Try bridging B+ and FP in the diagnostics, this sends a current straight to the fuel pump... the firing up momentarily can also indicate the fuel pump is initially priming, but not running when the engine fires ( again possibly ecu controlled to kill the engine )

right, firstly thanks for all the help JJ, i'll try bridging the conectors (not sure where they are though) a pic may help me

Open the diag port in the engine bay. Stick a paperclip between TE1 and E1, then turn ignition on in the car. Depending on how the engine light flashes is what code i.e flash flash, pause, flash would be 21. If its constantly flashing 2x a second then that means there is no faults.

[eddo]

right.....................ITS ALIVE!

problem was the ignitor plug was loose as the rev 3 plug doesnt fit very well.

Thanks to everyone for the help

[JJ]

[eddo]

well.....looks like i spoke to soon

went to start her up today and there is no spark now, well very very weak

swapped the ignitor for another spare one and thats no good.

dissy cap, leads and plugs all ok.

Please help me JJ

[JJ]

have you done the above diagnostic yet ?? this can save you a lot of downtime trying different things....

[eddo]

slipped on the rev 3 ignitor and all is well and running swell

big thanks to everyone
