Need help my 1jz is acting up and don't know what it is, my car turns on and immidiatly turns off, I hold the throttle and it starts making a sound like if it has a cam and throws a lot of black smoke from exhaust, I checked plugs and coils those are good, what could it be?

take your ecu apart. sounds like your caps are blown. Thats what mine use to do. Replaced the caps in the ecu and went back to just burning oil :biglaugh:

Put your ecu in his car so you don't accidentally fry his due to a short or something. His car is your control group, since you know it works.

Were you having this problem before the caps were replaced? Did the problem just appear or some thing you were doing before that (back-track)?

It did it from one day to another, nothing big just the daily couple runs with cars on freeway going home from work and the next morning it started acting up,
