Galant start issues

[Westgatez]

Hi, my 52 galant V6 will start and then die after a couple of seconds.
The car had its intake manifold off to correct a leaky rear rocker cover.
Whilst I was at it, the timing belt water pump and all the other belts were replaced.
Checked everything to make sure its all connected.
No lights on dash.
Not ran any codes yet.

anyone have any ideas they could throw out there for the time being?

thanks.

Connected up all the wiring plugs. Cam and crank sensors one are often the ones to forget

Yeh, they are all checked, code reader returned no errors. Was running fine before manifold was taken off.

Have you checked the timing?

check all intake piping

When the timing belt is removed, the two camshafts can sometimes turn over slightly by a 1\4 revolution or so, because the tension is removed, however when it was removed they stayed completely still, which was an added benefit, so our mechanic didn't have to check the timing. It was removed a couple of times, and it was working fine before, however on the third removal (gasket wasn't seated properly) and replacement it could start up, but not hold on idle.

If it means anything, the idle revs were a little low so we adjusted them to about 850, at warm, but after it was switched off and back on, it seemed to reset itself.

IAC was dirty
