PSD No Start

[wooby99]

Hi! I am having problem with my 2000 F250 PSD (stock). Randomly I have no starts but only when the parking brake is applied. I will try to start it, it cranks over but the wts light will not light. If I apply and release the parking brake a few times the wts light comes on and it starts right up. This problem has only occured twice before ( in two and a half years), but now it has happened three times in the past two days. Looking to the experts for help. Thanks

The parking brake kind of throws me off because IIRC it is mechanical not electrical and therefore should not come into play. With that being said have you replaced the CPS (Cam position sensor). When they are going out or do go out they notorious for intermittent starts or shut downs. Hope this helps ya',.

Yes I have changed the cps less than a year ago when it left me dead on the highway. Just before it went it left me signs of going...harder starts and poor performance.

I would be checking the battery voltage. Low voltage can cause a no start situation. As in the truck will crank but will not start.

Yup,
Back tracking see if your terminals are tight and free from corrosion.

Batteries and terminals are good, as are the oil and fuel filter all were changed/checked about five weeks ago. Could it be something loose under the dash since releasing the brake and letting it snap back corrects the problem, but I would not know what to look for though.

If you truck is like mine (a 95) that has a kick panel next to the parking brake, take it off and see if there is a loose connection or if the cable is catching on something. Where are you located?

I am in Pocomoke MD, just south of Ocean City MD, right my son has my truck about 170 miles north in Joppa MD. Four out of the five times it has happened he was using it, like now. The very first time it happened to me at a drive thru, had to get pushed out of the way, then towed home..fun!

Just an update and also need some advice. My son and I thought problem could be something loose. Today after 1 hour of trying to get it started he popped off the inside fuse cover and checked fuses and relays, the truck wts light came on and the truck started right up. Any ideas on what fuse or relay could cause the wts light not to light and truck not start, so I can tell him what to look for if it happens tomorrow on his way back home. Thanks
