1999 Ford V10 gas, starting problems?
I've owned this Ford F-53 chassis V10 for 6 years. I keep it in a storage yard here in Ohio over the winter. In the winter I start up the coach about every 3 weeks and let it run for about 20 minutes. I keep Sta-Bil and gas line antifreeze in the fuel. Summer or winter, hot or cold, I've never had a starting problem. One bump of the key and she starts, till now.
About Feb during one of my 3 week startups it faltered on the start and died. Faltered and ran just barely for a few seconds then ran normal, like a top. Again about 3 weeks later it faltered and faltered and finally caught then again ran like a top. The problem seems to be getting worse.. but so far it's not taken more than about 30 seconds to getting it running normally.
Once it's started if I shut it off and restart it, it starts as normal. 30 minutes later it starts as normal. An hour later it starts as normal. An hour and a half later it stumbles then starts.
Next morning it's back to the same starting problem as I described above... It's like it's not getting gas initially. Like the gas line is losing pressure??? I've traced the fuel line back to the tank and no leaks. I've inspected the engine and no apparent fuel leak. No smell of gas fumes. I'm perplexed. Does anyone have ideas as to the cause.
PS What I mean by faltering is it starts but dies immediately.
