*UPDATE* 20v not starting! SOLVED!

[Wanabe_Garage]

Hi

I know there are alot of these topics and i once had this problem before when i put the 20v in but now im really stumped

Car was running fine before i took it off the road for a week and a half to do my diff converstion,

now after completing the converstion.... the car doesnt want to fire up.

Things ive checked:
- Battery in good working condition, near new (i even jump started it just incase)
- Both fuel pumps are working, and i see fuel going to the engine
- The tested for spark and it sparks while the engine turns
- I checked all the fuses, they were fine
- I used a multimeter to make sure power was getting to the efi system etc, it was

I havn't opened the bonnet the whole time during the conversion until today when i bled the brakes.

Can anyone help? maybe ive missed something

*UPDATE* i really think now its the coil/ignitor not working

I decided to check spark again and at times im getting nothing and sometimes a spark here and there
thanks in advance

EDIT: Sorry, you mentioned you had spark, i will keep thinking

yeh i pulled out the plug and had it sit on the rocker cover

it zaped at a pace of about 1 per second

Check all wiring and earths that might have been unplugged during the conversion, even in the areas that might not have needed to be unplugged.

And then check again :) You would be surprised what can cause it not to start.

What exactly doesn't it do? Does it turn over or not? Or doesn't it want to start the engine at all despite being able to crank? Not sure exactly, some more info may help :)

I turn the key... its cranks and cranks... and but it doesnt wanna start

im still trying to figure it out wiring seems fine but ill keep checking thanks

hmm, u say it cranks, but doens tstart, the only thing i can think of now is fuel, but u say all thats alright, u checked our injector plugs/injectors themselves, i assume all the clips would be on so i doubt it would be this, but its worth a look

hmm... ill suss it out

easy way to check your injectors is to put a long screw driver on the end of one, crank it and if you put your ear on the end of the screw driver (handle end! :lol: ) it should make a clicking sound :D

im not really getting the screw driver thing lol

well now ive been playing with the car a bit, the car can sometimes combust but struggles to stay on

thinking its the ignitor atm.... how can i check?

so you have fuel and spark? only thing missing from the equation is air. Check your afm is functioning correctly, blockages etc.

if you are pumping the throttle does the engine still tick over? or does it still die regardless?

Back firing??? Through the exhaust or intake??

Problem SOLVED!! well at least i hope so

All I did was YELL at it a whole lot!...

And from what i could tell it could have been the ecu or its connections
I pulled the whole thing out, inspected it and reconnected it all

I tried it again and it still wasn't going but i kept on letting it turn and finally got going
it runs as it was.... and hopefully will keep on doing just that

thanks from all your help and giving me new things to check.
