2001 7.3 serious trouble, please help!
Hi gang. I am in need of some guidance here. Today, my beloved 01 F250 went TU. I last drove it around a week and a half ago. It has recently been mildly chilly, around 30 degrees. Today when attempting to go to the store I ran into the following problems.
-VERY VERY hard start. It literally took 5 minutes to start the bugger. It would just try to turn over with intermittent sputtering for about 30 seconds each attempt. When it finally did turn over, it would sputter like an asthmatic and shake like crazy. The RPM's would hover around 300 and then just die. When I finally did get it going, I had to give it throttle to get it to stay over 500 RPM's.
- After about 2 minutes, it simply turned off. After more hard starts, it would fire off but the RPM's would just drop to 0 and die. If I hold the throttle down, I can keep it there for a while at any RPM, but as soon as I let off, it drops all the way down to 0 again and dies. Finally, it would hover around 400 RPM's but would again just die after several minutes.
-While attempting to just shuttle around a little bit, I would put it in reverse and it would back up a little, then just die. Literally just shut off. The idle RPM's would never break 5-600. Normally it is around 9-1000. While pulling in my driveway, it died again, no warning, just died.
-Also, there is a sort of buzzing/ humming sound that increases when I apply the brakes.
-I do not have a block heater.
-I have recently replaced the CAM sensor.
-Service Engine Soon light is always on, maybe exhaust related?
-Water in Fuel light comes on sometimes just before it dies.
-It has worked fine until now, no problems in the last weeks.
Please help. I literally have no idea where to start. Thanks.
