89 TR starts and stalls

Vehicle starts and stalls. Fuel pressure is in spec. New fuse box, someone has installed a new voltageprotection relay. We unplugged the temp sensors vehicle started running ok. plugged temp sensor back in and problem is gone. Any advice anyone scene this problem before?

Probably bad connection on T1 or t2 sensors.
If these are disconnected completely then ECU
reverts to basic settings. (get you home mode) Unplugging and the replugging has probably somewhat cleaned the connections and the sensors are now giving the correct data

May I ask what temp sensor your referring to? Is it the thermo-time switch located on the "gooseneck" at the front-top area of the motor? There are multiple sensors located there....did you unplug all of them? I have a TR and would like to know.....Thank You.

it's the black connector on the gooseneck. That's the temperature switch. And the brown is the thermotime switch. Vehicle now starts and dies. If we disconnect the themotime switch the vehicle just cranks and dosen't start.

Have you checked CO readings on start-up to see what the motor is seeing?

well we got the car warmed up it was running ok. As soon as we unplugged the temp switch vehicle died. We are getting a new temp switch will keep all of you up to date on this one.

Well we replaced the temp sensor. The smaller 2 pin switch on the goosneck. Vehicle now starts and runs fine cold or hot. Everything at the moment is a go, and vehicle is on the road. Thanks for all your help. Oh we did reset fuel mixture due to it being out of spec. thanx JR
