Hi, I have a 99 catera (just bought used) it turns over but wont fire on the first or second time but for some reason will start on the 3rd try. I took it to my local repair shop. They said it seems to take up to 3 trys to get the fuel pressure up. They are not sure if it is the fuel pump or main computer. Any ideas? I am going to have them replace the brake booster, after that I guess I am going to my local dealer to have the no start checked.
