Hey everyone I have a 1991 Supra Turbo . I added a K&N air filter, 3in downpipe ,Greddy Type S BOV ,manual boost controller and fuel cut defender. I turned the boost up to 12 . I took it out ran it a couple of times seemed to do fine . Then I had it at about 50 mph planted my foot it boosted to 12 then cut out. I looked down and the rpm gauge bounced a couple of times below 1000 rpm then nothing. It wont start .When I tried to start it it would sound like it wanted to start but would not. I checked compression on all cylinders and they are around 125 psi. Then I checked the fuel pump it was fine. So know Im stumped. I read it had a cam position sensor. I dont think the timing belt slipped . I checked the belt and it looked good. And I dont know if the sensor would shut down the motor . I also pulled a plug and it had no spark when I turned the car over and the plugs are new .Any helpful suggestions ? Thanks
