[T3] Bad day at the (FI) office

[Keith Park]

Jim,
have your checked your fuel pressure when it acts up?  Remember way back
when when I had that pressure regulator go bad it spiked the pressure and it
would flood on startup, but I was always still able to start it on all 4
after holding the throttle wide open for a bit and it never hydrolocked.

The 73 will not run without a head temp sensor, neither will the 71, I dont
THINK the 69 will but I can say that for sure.  Open CHTS will shut off the
injection.

You need a simple SPDT switch?  Ill have to look in my box of switches, I
may have some of these.

Keith

Yes, adding the switch made it POSSIBLE to drive the car again. 
Unfortunately that 3-position special function switch was expensive 
and hard to find. The good news is that it's a nice heavy duty toggle 
switch.

The short answer is, "I don't know."

The longer answer is that I suspected there was a problem with 1 or 2 
injectors, which were sticking open at first and letting too much 
fuel in. I also had a couple times when the engine was hydrolocked on 
startup, making me think that a leaky injector had filled a cylinder 
after shutdown. Now I'm beginning to wonder if my CHTS resistance has 
gone to infinity when cold. That car sits most of the time in the 
winter, so the gas mileage is always awful then, but I've had a few 
medium sized trips with it this spring and the mileage was still down 
to 15 mi/gal. That's what made me think this resembled Daniel and 
Jessica's troubles.

We've had minimal good weather here so far, so I've been unable to do 
any real troubleshooting, so far.

On a cheerier note, I just picked up a new (to me) Bosch D-jet 
tester. This is the latest, GOOD Bosch tester, with the snap action 
switches. I haven't had a chance to try it yet, but I think it'll be 
in good shape once I get it cleaned up. This is one I used years ago 
and it worked well then. If all goes well, this means that I should 
be able to rent out my other one to anyone willing to put down a 
significant security deposit.
