If i'm wrong, then my apologies.

If i'm right, you'll have to retime it.

It doesent allow me to publish more than two images. On the camshaft the timing is right. And on crankpulley

In that case, my apologies, you timed it correctly!

Wouldn't be the first time though that someone has timed the cam incorrectly! Those marks are confusing because TDC is "hidden".

Have you checked all the fuses and relays are pushed fully home? Also check fuses #1, #11 and #12 or 13, can't remember off the top of my head so check both.

What starting fluid are you using?

Have you checked for any broken/split/missing hoses on the inlet manifold? Also have you checked the carbon brush in the centre of the dizzy cap hasn't broken off? It can and does happen, even on new ones!

A silly thought has just crossed my mind, you hadn't recently filled up with fuel when it stopped had you?

Thanks for your reply

I have new rotor and distributor. Also. Hoses are fine.. Fuses are fine. I’m using Walmart starterfluid

Double check the carbon brush hasn't broken off the inside of the distributor cap - seriously, i've known it happen on new caps!

Also check the HT leads are pushed fully home on the cap and coil, also on the plugs.

What gap did you set the plugs to as well?

I have checked relays, coil, rotor, distributor. It has spark

Are you getting a spark at the plugs? If so, what colour is the spark?

Hello

So reading back through the current posts you have made.....

You have good compression....Is this on all cylinders?

Timing checked and you believe it to be correct.

There is a spark....rules out crank position sensor.....or does it?

And you believe there is enough fuel. Have you pulled the plugs and found any to be wet with petrol?
Fuel pressure regulators have been known to fail in either under-fuelling or over-fuelling scenarios.

You initially said you lost power. Was that gradually or abruptly ?

Try unplugging the mass airflow meter. They have been known to cause a non start issue. The ecu will see this and throw set of emergency values to the fuelling system.

Is the fuel old and stale? I have had it where petrol only 3 months old in one of my classics caused complete non starting. Tank drained and new fuel added. Started straight away.

Everything you have mentioned I have tested. Gas regulator works and has tested. Have tried to unplug Mass air flow sensor. No luck. Tried with another plugs no luck. It’s 2 days old fuel. Plugs are wet off of fuel. Good compression 11bar
