Hello all,
I'm looking for some help with my Blue Bird (being converted to an RV or coffin whichever comes first). The lot I have it parked in is getting paved and I have to move it. I haven't started it since Oct 2018. After that, the batteries went dead. I've replaced the batteries and got it to turn over easy enough but it wouldn't start. Fuel filter was full of fuel. I dumped a little out to see if it would re-prime. It did not. When I measured the voltage across the lift pump I was getting 1.78VDC. I didn't think that was right and hoped that replacing the lift pump would solve the priming issue. That didn't resolve the issue.

Can anyone tell me where the relay is that controls the lift pump or what else I should look for?

Thanks in advance.

'99 Bluebird, 8.3L Cummins ISC, VIN 1BAANB7A2XF085392
