Help - won't start

[joyful trave]

1997 Winnebago Vectra with 3126 Caterpillar diesel engine on a freightliner chassis, with 23000 miles. Was running fine but now engine turns over but won't start. Have changed fuel filter, it will run with silicone spray, but guess it won't pick up the fuel. I think its an electrical problem. What is the most likely electrical problem? Have checked all fuses I can find, both in fuse panel under windshield and fuse in line on the wiring harness. Where do I go from here?

Check for engine protection module.

These sense low oil or high temp and shut off fuel supply.

Ours was unplugged once and did same.

Different chasis and engine but still may be...

Or you have problrm wilt fuel selenoid valve.

Diesel are fuel control engines as no ignition so look for fuel system related electrical.

Soon others with same engine may provide better directiin.

Try googleing yiur engine and fuel control and you may get ideas too.

Did this problem start before or after you changed the fuel filter? Rook
