99 Intrepid 2.7 wont stay running
I have an Intrepid (185k miles) that I can eventually get started after a few tries. It takes me about three to four long cranks to get it started and I have to give it gas to get it up to about 2000 rmp's and hold it there for a bit while it warms up, otherwise it will just die on me. Once it's warm and I slowly bring it down to idle, it will stay running but very rough.
I pulled the plugs and all six were completely black. I have two leaks coming from the exhaust, one coming from the exhaust pipe and the other from the muffler, both seem to be just water/condensation.
Air filter is good, throttle bottle is squeaky clean, I pulled out the IAC and cleaned it. I've switched out fuse/relays for the fuel pump and ASD. I replaced the spark plugs
After all the checks above, I did a fuel pressure test on the fuel line, at the point where the fuel rail and fuel line connect. It topped out at 45 psi, it slowly worked up from 0 to 45, it probably took about 60 to 90 seconds to get there. Once it reached 45 psi, it held there for about 10 minutes then i shut the car off. I ran the test two times on two different days and got the same results.
My question is, does that rule everything out and pretty much indicate that my fuel pump is bad, or is there still some other possibility?
