Omega General Help / Re: C30XEI/C30SE wont start

« on: 07 March 2023, 21:09:07 »

Its alive!

And the same issue and right answer below.
Did a timing check and turned distributor counter clockwise about 60 degrees.

Fired up nicely and sound great again.

Thank you all for help!

Distributor refitted in the correct orientation?

Don't take this for granted... Had a V6 Granada that barely ran following a plug and lead change. Turned out that the distributor had previously been replaced and had been clocked 60 degrees out. Moving the leads one post round cured that.

This won't change the firing order, but it really messes with the timing of the spark vs fuel delivery and consequently the combustion process.

And the leads?

Fine, right order and all good.

So.

Cleaned the relays and no victory.
Also changed some relays to make sure.

When ignition ON, there is 12V in the injector harness when voltmeter is from injector pin to battery negative terminal.

Does it state the working V on the injector itself?

They're driven by the ECU, possibly via a 12v relay, so it's possible that the 1.5v is the reference voltage. 

You didn't say if the leads had been removed from the distributor or not

Sorry, yes they were removed.

Firing order is 153624. Double checked.

One end of the injector should be at battery voltage - 12V ish - when measured to chassis/battery negative terminal. If it isn't then either the injector relay has packed up, or a fuse is blown.

The ECU grounds the other end of the injector to operate them - but only for a few miliseconds at a time. You won't be able to measure 12V across the injector plug/socket itself with a voltmeter.

Where i can find relay for injectors?

It is Omega Evolution 500.

Plug leads are used, but in good condition and clean.

At the moment i fount out when i crank, i have only 1.25V of power in injector.

Should it be 12V?

Thanks for fast replys!

Didnt turn the distributor and i think timing hasnt changed. (also distributor cap is not 180c wrong, its correct)

Injectors and car worked 3 weeks ago. Today there is no even pop and bang in the combustion chamber.

Compression test was 10-11bar in every cilinder.

Hello guys,

Looking for some help to start C30XEI (same as C30SE) again.

Changed spark plugs and valve seal. (Firing order is not changed 153624) 

After that car wont start anymore.

* Fuel pressure is 2.5-3bar and its okay
* Spark is good
* Mass cables correct, cleaned and good
* 98octane fresh fuel
* Fuel filter new


Any ideas? cuz i dont have anymore
