So the motor is out :twisted: due to the fact i had water in my sump AGAIN and had exhausted every other idea i had. So its out and i have removed the timing chain cover to reveal a very worn chain and a wear mark through yes through the timing chain cover itself allowing water passing through the water pump to go straight into the sump. So i have checked out a few replacement timing chain covers and it seems that this is quite frequent all the ones i have seen have had slight wear in this area. So i am planning to pick the best one and take it to get welded to avoid this in the future. SO before the cruise i must purchase new clutch, timing chain cover, gaskets, and other stuff and bolt it all together put it in the car get it running. CHALLENGE EXCEPTED (will upload photos later, not important right now, do not have time haha)

The engine is back in, went smoothly. Those who were on the cruise today would know she didnt make it however when i got home i played around and unplugged the regulator, and poof it works (THANKS ETHAN!!!!) so now with 12 volts to the fuel pump she works like a dream. However not sure but the altenator may be stuffed but we shall soon find out.

Thinking about it a bit more Chris, I'd say your alternator is on it's way out after all. I remembered that the charging system works the fuel pump relay for safety in case of an accident (motor stops, charge stops, no more fuel pumping out).

The "fuel pump trick", is actually one way to diagnose a faulty pump. If you disconnect the reg, and it runs sweet, then you know the pump works fine, it just isn't getting enough power to provide adequate pressure (4.5psi or whatever it is).

Since Gems run externally regulated alternators, unlike say, the N13 Pulsar ones we like to pinch, disconnecting the regulator means that the relay is getting maximum charge possible from the dying unit. It may only be charging 10 or 11 volts, but with the regulator connected the fuel relay will still be getting less than what it needs (6 or 7 volts when it needs around 8.5).

Get a multimeter on it if you can, and see how much charge you're getting. Chances are it's running a bit low ;)

if you need an alternator to test/replace it with, i have a couple of spare ones in my shed that are definitely good units.
