[Diy_efi] Nissan engine

[Bobby Yates Emory]

Ian,

Restart procedure sounds about right, but I would use Marvel Mystery Oil.
Put a couple of tablespoons down each cylinder.  Let sit over night (or a
day or two).  Put another tablespoon down each cylinder.  Turn engine over a
few rounds with a socket on the harmonic balancer bolt (sparks plugs out and
ignition off).  With the plugs still out, turn over a few times with the
starter (this is to get all the excess oil out of the cylinders).   Then
install plugs and try to start up.

(Caution - I have heard that electronic ignitions can be damaged by running
the engine with one or more wires off the plugs.  So it may be worth your
while to rig up a way to "hit" the starter, without turning on the
ignition.  I don't remember how the starter solenoid worked on my 240Z, but
usually there is a small stud on the solenoid which you can put 12 V to and
it kicks in the solenoid which connects power and engages the starter
drive.   I am not certain about this concern - I could be worrying
unnecessarily. Anyone know for 280Z?)

Good luck,
Bobby
