- 1997 Mercury Mountaineer
1997 Mercury Mountaineer 5.0 L AWD. It runs good when it starts. It always starts right up when it's cold. When it gets up to operating temperature and you shut it off, it starts right back up. When you let it sit for 20 to 30 minutes, sometimes it cranks for 10 seconds then starts, sometimes you have to floor it to get it to start, and sometimes it won't start at all. So far I've put 2 fuel pumps in(first one was bad from new), new fuel filter, new fuel pressure regulator, new crank sensor, new coolant temperature sensor, and checked all the voltages to above parts. I have 40 psi fuel pressure and spark when it starts and when it doesn't start. The battery tests OK and the starter doesn't draw too many amps. I give up. Help please.
