My '08 Nomad 1600 was getting harder to start, and last week, when I returned from a (car) trip, it wouldn't start at all. The original battery had 34,000 miles and four years on it, so I replaced it. The engine turns over, but still won't fire up. It does when we (mechanic and I) sprayed starter fluid into the system, but fuel is not getting to the cylinders.
We checked the inside of the tank...clean as a whistle, which makes a clogged fuel line unlikely (but not impossible). My mechanic has 25 years of experience and he's surprised since he's never seen a clean system clog up, so he's thinking it might be a cam position sensor gone bad.
Any thoughts on the matter, anyone?
I'm retired on limited income and this might be painfully expensive.

Vulcan FI systems are known for being sensitive to low voltage. A weak battery or even a new battery with a low charge can cause fuel injection problems. Double check your battery terminal and frame ground connections, then check the wiring harness connections also.

The mechanic found the problem. The fuel pump has a built-in filter of gauze, and even though the tank was clean, enough fine stuff got through the filter and built up in the line to the injectors. The back pressure caused a nipple at the outlet of the pump to split and the fuel never got to the injectors.
They don't sell this nipple alone. He tried fitting in a hose, then tried fixing the nipple with O-rings, but neither idea worked. I'm afraid this means a new fuel pump at nearly $500.
Sorry about taking so long to respond.
