ok i am not sure n=but i think i made a dumb move. i tried starting this supra that i bought, i t had a shitty turbo inlet and non of the hoses were connected including the blow off, but it started up a couple of time then cut off, so i played with cps, then it stayed on, then shut off maybe because of no gas, so i put some gas in and replaced the hose but didn't yet have the other 3 connecting whose, and then i started it, then i spurted and would start, the starter wld even start, and the everything went dead. so i am thinking that thinking that the ecu is done..help
