I'm new to the forum, so I hope somebody can help. I have a 99 dually, 7.3l, brute force intake, and a 4" exhaust. Sometimes I chips it with an Edge Evolution. So my problem is ever since the recall for the cam sensors I've had to change mine three more times. The truck just won't start. I get the cam sensors from the Ford dealer. There's no check engine light coming on. So any suggestions would be great. Also the sensors seem to last about 3 months then start acting up..Thanks
I haven't check in a while for codes. Occasional the truck won't start and when driving just above idle, like through a 25 mph zone, truck starts to buck alittle. some time it sounds like it might have a slight miss. If i change the sensor then its fine for awhile. I'll double check for codes. Thanks
big issue for me was the addition of supplemental biodiesel by the fuel shops around mid-mo, is now a state required for 5-10% blends; I was seeing some spots on the drive and smell of fuel ever so often during driving, found my FF bleed or drain valve assembly leaking. Was OEM, had black I presume silicone rubber o-rings, some form of synthetic but not compatible with the fuel, they had swollen and the unit leaking in and out. Fuel was draining off at night and leaking during day, some hard starts and always a slight miss until well warmed up. Swapped it out and the problem stopped, new o-rings were yellow.
With your 99, does your tach needle move, on a long extended crank, when it doesn't start? If the tach needle doesn't move, its the CPS. 99 thru 01 trucks have their tachs wired through the CPS circuit. If the needle bounces, then probably not the CPS, causing the no start.
