Working with the fact that you had overheating and we have discovered
that retarded cam timing can cause overheating, plus a sudden drastic
change in engine operation, I'd say that a loose cambelt has jumped a few
teeth.

It is not unheard of for the cambelt to jump teeth during an engine stop/
start cycle. Not sure why but the belt has to be loose (or severely worn)
for it to happen.

The cold start injector only supplies fuel when the engine is cranking. The
engine will only continue to run for a second or two after you release the
key if the main injectors are not working.

Dear jondee86.
Today check again on the 4age 16v RWD. for the timing belt is still at the place that it. No jump teeth found (refer attachment photo)

But i found that ignition cable 1 and 4 with totally no ohms on it (sound funny due 2 cable in same time?)and had replace all the ignition cable to new. Test start result remain. Totally cant start at all.
