This is going to be hard to fully explain but here we go.
The car is a 99 GSR all stock

update.
-tried a new ecu same problem
-tried a new main relay same problem

sorry for the throw up of words!

I was driving the car today normally and i got a cel and nothing came from it for about 10 miles. Then i was sitting at a light on my way home and the car died. turned off and restarted and started right back up. Made it home and tried to jump the clip to check codes and all Im getting is a solid cel light. And yes Im jumping it correctly i have done this many times before with other cars. Then i had a buddy bring a scanner over and it said pcm malfunction so we thought that it was the ecu that went bad. Bought a Ecu From one six that i would say is good and thought the problem would be fixed but after about 5 seconds of running the cel came back on and idled normal and fine for about 30 seconds then it just shut down. The car can be restarted right away and will run for a random amount of time then out of no where just shut off. Sometimes when it is restarted it idles like its possessed anywhere from 3k to 500. if the ignition is left on it sounds like the fuel pump keeps priming over and over instead of just once like normal. Any help would be great because i don't even know where to start with this.

 

anyone that can help

 

well with new plugs and fuel filter and the new ecu bolted up its running fine and no cels are coming on. I guess its fixed.
