Being in the middle of the same event with my *new* TR8, here's where I am
at. Car runs 8 seconds when cold. That's the time to cold start injector
cut out. I can fire once or twice more for diminishing times each time,
until no fire at all on the 4th try or so.
Put the blade of a big screwdriver on the body of an injector and stick the
handle in your ear while someone else cranks the engine. Listen for the
clicks. If you hear clicks you injectors are actuating so the electronics
is ok.
Depressurize the fuel system (or let it sit over night) and disconnect the
fuel to the cold start injector. Attach fuel pressure meter. I found a
meter at AutoZone for later model cars that have the valve to attach the
meter to and found that if hold the locking barrel fully forward you can
whack it off with a hacksaw and leave enough of the underlying connector to
put and hose and clamp with a hose clamp. Viola for $35.00 you can check
your pressure.
If less than 35 Lbs pressure then see if fuel pump is working, if so,
replace the fuel filter and check again. Low pressure at this point is
either the pump or the pressure regulator.
If pressure is/was normal then the injectors are clogged. This is where I
am at. I plan to pull the plenum and remove the fuel rail with injectors
attached and crank the car to see if anything at all is coming out.
CAUTION! Disconnect HV coil wire and have fire extinguisher handy! I am
going to get a turkey pan (one of the cheap aluminum ones from the grocery)
to put under the injectors to catch the gas.
Assuming they are clogged I have found a place nearby that will disassemble
and clean the injectors for about $15.00 each. Also I have found rebuilds at
about $45 per and new ones from $80 and up.
Going back to the top, if there was no clicking check the combination relay
near the fuse box and/or the ballast resistor pack next to the coil. These
provide power to the ECU and the timing for the injectors firing. Power to
the cold start injector runs through the combination relay, but not the ECU.
Good luck, let me know what you find, as I am right there with you and quite
ready to drive the 8.

Can someone help Harry with his TR8 fuel injection problem ?
I've never even been under the hood of an injected TR, so I'm no help.

I saw your posting on the TR list and wondered if you could help me
figure
out why my fuel injected TR8 wont start. The cold start injecor will
allow it
to run for a second then it dies. I put a friends known to be good
computer
in it and still nothing. Im thinking the computer is either not getting
power
or a signal telling it to fire the injectors. Any idea of what to check
next.
I dont have any idea which pin on the connector would supply the
computer
with power or if the only power in comes from an engine sensor. I get
the
list in a digest form and dont know hoe to post to it so could you email
me
back directly. You could shre this with the list if you like I noticed
jaltman is also having injector trouble.
Thanks Harry in MD
