sorry about the wait, like most experts on here I'm not online all the time
OK if you can't get fault code then
1st check for spark by removing one of the spark plugs and plug it back into its lead and rest it on the metal of the engine ( DO NOT hold it on place by hand) then have your assistant turn the engine over whilst you watch the plug. It should give a fat blue spark at regular intervals.
If not then check that there's power to the coil pack (at the other end of the plug lead) using a meter. If there’s 12V at the pack but no spark then check the ECU power supply (fuse and relay) and also the connections to the crankshaft speed sensor.
If there is a spark and its still not starting then its likely that the ECU isn't opening the fuel injectors, if the injectors are working you can hear them click - its difficult to hear them with background noise so use a long screwdriver like a stethoscope, placing the handle end in your ear and the metal tip against the body of the injector whilst your assistant turns the engine over.
If you can't hear anything check the ECU power is present by measuring voltage at the fusebox and on its relay socket if OK then check the connections to the crank speed sensor and consider replacing this sensor if the wiring / connections look OK
If the car will start using a squirt of quick/ easi start into the intake then this confirms the problem is lack of fuel

Hey Matt is that you, thanks. Checked everything, change ECU, but still no electricity from the dustrbuter/a magnetic type. No electricity from the spark plug when engine is franked.

OK thanks for the extra information
if its not sparking and there's no power / 12V from the distributor then 1st ceck that the engien earth strap is tightly connected and not corroded at the engine and the battery end
if this is OK then I'd check that you've got 12V going to the ignition amplifier at the back of the engine bay as its this that powers the coil and provides the switching from the distributor pickup
