We have been out in the Stretch for over a week now and all has been going well except for one annoying problem. When the engine is cold (well cool... this IS in Southern Calif!) & the Outside Air Temperature is below about 50F, no problem. If we get a later start & the OAT gets to 60-70, it seems like the battery will run down before it starts. Hot starts later in the day after a lunch or fuel stop are almost instantaneous.
My procedure for a cold start is; electric pump on, depress accelerator half way to set the choke, & I am rewarded with a very quick start. That does not work when it is warm, so have also tried not running the pump, not setting the choke, and the combination of those two... still no go.
This is a fresh (4000 mile) 455. When it was installed, we also put in an aluminum intake, new Patterson Quadrajet, Distributor, & Plug Wires. The Plugs are new NGK 6BKR6EI. There is no mechanical pump, have a Carter 4070 on each tank.
We did not use the coach last spring and summer due to our medical problems so this trouble is new to my experience with this motorhome. Have not had the engine cover up to look during one of these episodes, the pressure to get going makes us start off, just glad to finally have it running!
Any ideas or suggestions will be much appreciated.
