I bought the truck about a week ago, went to go look at it and it started up great and ran great no hiccups or anything. Two days later, the day I bought it, it had very low fuel, (on Empty), well I drove it approximately 5 miles to the closest fuel station and filled it to 1/4 just to get home. Ran great on the way home. Truck sits for a day in my driveway and when i go to fire it up it idles good for about a minute or two then stalls as if the key was tuned off. Go to crank it back up and it starts fine then stalls again. I continued starting it and letting it idle a couple more times until the idles got choppy and started surging. Still has the same 1/4 of fuel in it.
I tried to get as much data from the truck as I could while it was running, ICP
was about 500-800 cranking and 400-700 at idle, duty cycle was around 14-27%.
I replaced Cam Shaft Position sensor with a gray one from the auto store. Made no difference. I unplugged ICP
sensor (it has oil in it so probably bad) and the ICP
ratings were higher, about 1000 cranking and 800-1000 at idle. But it still stalled after about 1 minute.
When the engine stalls the only lights on the dash are a "service engine soon" light and the "engine oil/coolant temp light" that one is usually always on, not sure why.
My next course of action is going to be replacing the fuel filter and seeing if the pump is filling the bowl, and if there are any bubbles.
I only included the part about the low fuel because I am concerned that I may have picked up air in the system, or perhaps the fuel pickup in the tank got clogged. I know there will be a code stored since the SES
light came on, but the code reader I have#(the same one that works for my 04 6.0) won't pick up any codes from the system on the truck.
Where should I go next, I would really appreciate some input and guidance. Thanks!
