injectors not recieving pulse

[gotbeef18]

hi i just bought a 97 gst with a 16g turbo it only runs on cylinders 2 and 3 all 4 cylinders are getting spark just cranking and running. when you just crank over engine and put noid light on 1 and 4 injectors they work however when car is running 1 and 4 recieve no pulse signal i am pretty stumped maybe somebody can help me out with this one thanks

So, it only runs on two cylinders while idling or cruising, or both? Do you have a 6 bolt?

Cam angle sensor and power transistor are the two common culprits when it comes to this.

it runs on cylinders 2 and 3 when idling and driving car has 68k original miles so im assuming its stock motor, if cas was bad car wouldnt run at all im assuming so its not that as you can unplug it and it will not start same as bad sensor. i will check out that power transistor. im just a little confused why they pulse when cranking but not running just trying to figure out the mechanics of it why its doing that thanks

What does the car feel like/drive like on 2 cylinders?

its really sluggish and crackles/ pops the power transistor is fine and cam angle sensor are fine im not quite sure if it would be ecu as it does pulse the injectors when cranking but when it is running it will not kinda of strange any other ideas?
