AAZ Pump - Do I Connect Constant 12v to the Extra Timing Solenoid?

[8v-of-fury]

Almost looks like you have a 1.6 body there Steward.. Up by the fuel in and between it and the pressure regulator in the other side. . Is there a bolt or just a flat machined surface??

[stewardc]

Well, it was built by Giles specifically for my AAZ. Am unsure where you mean for that bolt.

[8v-of-fury]

Between the fuel inlet and the fuel pressure regulator directly opposite it. Looking at the pump from the front it is about a half inch directly towards the engine.

[stewardc]

There is a bolt there.

[8v-of-fury]

Ok. So it is an AAZ pump, without the solenoid on it. It is suppossd to have one stock. But apparently they have no use if Giles does not use them.

[stewardc]

Yeah, this one seems to have a nice stock cover where the solenoid goes.  I should note that this pump, stock, had no LDA assembly either.

Has anyone had a pressure gauge on the pump to measure internal pressure increase when 12v is applied to the selenoid? I'm curious to know how much it advances with power to it.

My pump is timed to .96-.97ish right now, and from what i've read this selenoid only increases internal pressure up to 3000 rpm.

So if my pump is timed to .96-.97 with the selenoid unpowered, and i power it, am i to advanced??? Possibly risking pump damage? I do like the extra power but not if it means severely decreased pump life.

The injection pump itself doesn't care if you are advanced or retarded.  It definitely won't hurt the pump to have it more or less advanced.  The only thing affected by timing is the actual combustion of fuel in the engine.
