Negative. However the hatch switch pulls both duties.

You may still have to go in there but it'd much less work to measure it first: http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=122 That section of the book can be confusing due to the poor nomenclature used as well as typos and for those who have an 87 TSRM it's a...

As was pointed out the cancel switch on the lock mechanism is likely not working. Since the interior illumination and theft deterrent system are separate I also don't understand what the other poster is getting at. Lastly, you don't state whether the key fob operates an aftermarket alarm or if...

^ Lmao. As a former resident of Borvallis, truer words were never spoken. The weather also sucks.

^ This. Not to mention the O2 sensor can't have anything to do with his problems...

It's not right. If it were a code 22 would have been set. There more in your posts that doesn't make sense and much of it implies a misunderstanding of how the EFI system actually works. Not that I'd be blaming it anyway. Most people are overly quick to do so when it's usually not at fault.

^ This. Check for fuel cut RPM: http://www.cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?Section=FI&P=125 If that pans out check the TPS and SPD input from the speedometer. ISCV can be tested per the service manual.

^ Lmao! Well done!

Correction by tapping indicates worn brushes and/or worn solenoid contacts, both of which can be replaced. And while they can be at fault for the problem talked about in this thread they seldom are.

10-11 volts is the problem right there. Indicates either a discharged battery or a severe voltage drop. Again, as I've said several times in this thread, all of these problems can be easily solved by the proper use of a meter. Just do it. Don't know how? Now would be a good time to learn...

No spark = no ignition confirmation to ECU = code 14 = no injection. Simple as that.

The only coolant sensor that can effect fueling is the two wire one on the engine side of the thermostat. As for 30 inhg, the death spiral of science education in America continues...

Was it timed after CPS replacement? It'd also help to know which sensor got busted. And even if 30 lbs of vacuum was inches of mercury you still wouldn't be on this planet...

Quite the story. All I'll say is even with all that I'd still swap places with you in a heartbeat.

http://www.cygnusx1.net/Supra/Library/TEWD/MK3/manual.aspx?S=Main&P=46 It's all right there in living color...

Guess those dotted lines have meaning...

Pilot valve for coolant shutoff to heater core: http://www.cygnusx1.net/Supra/Library/EPC/291420/catalog.aspx?F=8717&P=1 Test it. Most likely gone tango uniform...

All the info you seek is in the TSRM...including how to fix the TDS correctly.

Your friend screwed up...
