Re: [T3] Vapor Lock?


<x-charset iso-8859-1>
The little fire or 2 tells you alot!... if it occurs without your touching
the gas it means that your ignition system is probably OK, you have fuel
pressure, trigger contacts are atleast half OK, and that fire is from the
gas injected by the cold start injector.  If pumping the gas a couple times
makes it fire a few more times that means that your main injectors are
working OK and your firing from the gas injected as part of the accelerator
pump function on the throttle valve switch. Your just not getting injection
pulses from the trigger contacts.  Check:

GROUNDS... wiggle then try the 3 on the breather and the one on the engine
case.
Make sure the connector to the trigger contacts is good... and the one on
the control unit.
its remotely possible that there is a thermal intermittant in the control
unit but they are pretty darn reliable.

My vote:  dirty trigger contacts  OR a bad rivit connection in them, try
another set.

You engine WILL start when cold at 180... it will start, stall, require
feathering the gas but it will start... kinda like starting without a choke.

This is unnecessary, unless the car has sat for quite a while and then you
WANT to crank it a bit to get the oil pressure up before it fires off.  This
WILL inject a small amount of gas each time you cycle the key from the CSI.
