TR DIES

I FOUND A PROBLEM WITH THE FUEL PUMP CIRCUIT. WHEN THE CAR SHUTS DOWN AND I TRY TO RE START IT THE FUEL PUMPS OR FUEL PUMP RELAYS ARE NOT RECEIVING A SIGNAL TO ENERGIZE. I THEN BY PASSED THE RELAYS AS DESCRIBED IN THE WORK SHOP MANUAL I TESTED IT BOTH WAYS 3 OR 4 TIMES AND THE CAR RAN FINE. THE MANUAL TALKS ABOUT THE SAFETY CIRCUIT WITH THE U RELAY AND THE TACHOMETRIC RELAY THAT RECEIVES TWO OTHER SIGNALS FROM THE COIL AND THE STARTER RESPECTIVELY. SOMEWERE IN HERE IS THE PROBLEM I THINK. DOES ANYONE KNOW WHERE THE TACHOMETRIC RELAY IS LOCATED {IT DOESN'T SHOW THE LOCATION IN MY WORKSHOP MANUAL} SO I CAN TRACK THE WIRES DIRECTLY FROM THAT SOURCE. I THINK THIS IS A LONG SHOT BUT IS THERE A ENERTIA SWITCH IN THE 87 TR IF SO WHERE MIGHT IT BE HIDING THANKS

Tachymetric relay is relay S on the board. Look on sheet I19 in WSM. Signal comes from the key and left side coil I seem to recall, I cannot find that page in my WSM, darn these other guys!

THIS IT THE PAGE I HAVE RELAY #16 TO THE RIGHT IS THE ONE I'M LOOKING.<center><table border=1><tr><td>

MG,

sounds unlikely the Tachometric Relay is your culprit as it runs off only one coil. To shut the engine off completely requires shutting down both banks.

Page I20 in WSM, #26 is tachymetric relay. This supplies positive power to BOTH fuel pump relays which then operates them. the tachymetric relay is operated by either 1) crank signal via fuse #21
2) coil signal from LH coil
3) +ve from ignition switch signal white/red wire
I don't have a TR in shop, but the relay might be in thr RH wheelwell of the engine comp. I remember tracking a problem through those once.
Also had a no-start which was the connector block at the rear LH wheel well, mentioned by JRV. Definitely crack those and check the terminals. Otherwise look real careful at all of the fuseboard connections.

THANKS GUYS I'LL GO OUT AND START CHECKING IN THOUSE AREAS. IS THERE MORE THE ONE WSM.

Stand corrected on likelyhood of a connection to the shut down problem.

great info Brian...!!

I'M STILL TRYING TO LOCATE THAT REALY I LOOKED IN THAT BLACK ON THE RIGHT REAR FENDER WITH THE SMALL AND LARGE CONNECTORS. THERE IS 5 RELAYS IN THE BOX BUT NOT THE TACK RELAY. I TESTED ALL THE INPUTE CICCUITS ON THE FUSE BOARD. I BELIEVE WHEN I TRACK THE WIRES FROM THE RELAY I'LL FIND THE GREMLIN, ALMOST 1:00AM TIME TO STOP FOR THE NIGHT.THANKS FOR READING MY QUEST.

MG,

what manuels do you have?

I found the the tach relay behind the fuse panel it does not seem to be working properly. I'll test it over the weekend. A replacement is on the way,I now have a nice collection of good used parts. Oh well parts is parts.
