Newby here from Tennessee. I have a 99 3800 V6. My problem is intermittent. The engine cranks over, and almost starts, but then won't start. It acts just like a no fuel issue but I have 47 psi fuel pressure. It will not start w/ carb cleaner into the intake. I replaced the ignition module under the coils and it started and ran fine...for about 5 min. It has done this with the old module, too. There are no codes. At one point, I got it started but only while pumping the throttle. Can someone please give me some direction?
