Well, it`s been a while, but the problem was not solved that easily, the charging issue was fixed, but on the test drive the engine stopped again (No knocking sounds etc, it just plain stopped) thankfully in downhill not far away from home, so managed to roll back home!
Since then, I`ve done a lot of things but she wont start again The starter cranks the engine but the engine wont fire up.
1) Replaced Igniter with a brand new one, no go.
2) Replaced ECU with a 60 day warranty, function tested, used condition, of the exact same serial number as the one I already have, no go.
2) Tried a bunch of coils, no go.
3) Cleaned throttle body and intake, no go.
4) Checked all wires running out from ECU to TPS, Map, Ignition, Injectors and the few sensors I could reach, as well as plug leads (While attached to dizzy cap and plugs) and inspected dizzy cap and rotor, they all check out fine.
5) Taken Distributor out again, and made sure no slack in the distributor axle, made sure the sensor and trigger wheel was spaced correctly (no adjustment needed) and made sure the marks were all alligned (which they were) as well as installed correctly with crank+cams in TDC, again no change from status quo.
6) Made new engine block and engine head earths (New cables, new clamps, cleaned earth points on both engine block, head and chassis and firewall), again, no change.
Intermittently also checked timing belt alignment and tension out of pure habit (it checks out every time!) and also made sure for the 20th time that the crank pulley keyway is fine (which it is).
I`ve had another crack at putting ECU in diagnostic mode, not a single blink on the test lamp.
Checked Injectors getting power (which they do, but earth does not come on), checked ECU gets power from relay (which it does) as well as constant power from battery (which it does).
Had another 5-6 rounds on google, yahoo and hotbot for problems related to getting a 4AGE to start, but either symptoms dont match, engines/harness/generation etc dont match, and the few relevant issues that remain I have already ruled out a thousand times over.
.. Talk about getting more than I bargained for
