Grab a MM set it to DC Volts put a probe into each of the 2 wires for the Injector and see if you get voltage there!
You should be able to sit the MM so you can do this on your own!
(A test light would work as well)

ok do I have to turn the ign. on? and do I stick the probes in the injector or the plug?IJ. said:Sorry was eating

Pull a plug and put the probes in there then crank the motor, we're looking for voltage at the Injector as if you have fuel at the rail the injector is the last place it could stop before it gets into the motor!
Ok, pulled of one of the injector plugs and put the probes in the plug, cranked it, and didnt get a readingIJ. said:
Should just be the EFI fuse and I'm not sure if it has a relay or not (Standalone here)
Hopefully one of the guys that knows will jump in! <edit>

I suggest you read some of the FAQ's and follow the link to the Toyota Supra repair manual online, or TSRM. You will find the fusable links in the power distribution chart, and more specifically, in the component locator.x87SUPRA87x said:
Ok, so i checked the relays, fuses, etc. and havent found anything wrong, Is there anything else that I need to check?
Just trying to figure out what if anything has changed.
If there is power to the Injector Fuse then again at the relay there has to be a break in between. (you have checked for voltage at both these locations haven't you?)
Worst case scenario is a dead ECU but lets eliminate the easy/cheap stuff first.

does the Check engine light (MIL) come on when you turn the key all the way on, but not to the actual cranking point?
actually it doescjsupra90 said:
and IJ, now that i think about it i didnt check it at the fuse, do I pull the fuse out to check it there?

LMAO I thought you said you CHECKED it!! grrrrr
Pull the fuse put the MM probes across the fuse on continuity setting don't trust a visual!
Change the MM to V dc and test the fuse socket with the IGN on to see if you have power there (+ probe in socket and - to ground)

ok, I checked it at both spots myself this time, (my dad did it the first time) and aparently he was doing something wrong, because I am getting a reading and its coming up normal, I also managed to get ahold of a different FPR today and change that while I was at it, I can smell the fuel now after cranking it, but its still won't start i think my starter managed to go bad around the same time because it doesn't sound right and the battery is fully charged, or could my starter injector possibly going bad? does this sound logical to you?
