Injector connector problem

Hi guys,

So I have the most annoying problem I have ever encountered with a car...and if anyone can help with ideas/solutions, I will be extremely happy.

So it started a couple of months ago, whereby the the car would run as normal until turned off, and started again when warm.

It would then run on 5 cylinders.

I found out that it was the injector connectors, and have re wired all 6 of them.

Since then nothing changed, and have found out that the no.3 cylinder connector requires pushing down when restarted and then begins running on all 6 again.

I thought that it could just be a loose or dodgey connector, so re wired another new one in...nothing changed.

This is the current situation, whereby I am having to pushing/wiggle around the no.3 connector until it runs on all 6 after being run and turned off (then re started once warm).

Any help will be very appreciated as this is driving me absaloutly mad.

The car has a stock side feed rail with 800cc sard injectors

Thanks,

Tom

Swap number 3 injector to another position, see if the issue follows the moved injector or stays with number three wiring.
