Bus won't start after replacing fuel filters. HELP!!!

Hi �� I have a 98' international dt466e Thomas. I recently replaced the primary and secondary filters. Now she won't start. I replaced the hand pump, the old one was bad anyway. But that didn't work. I bought batteries but that didn't work. I've tried ether, nothing. What could be causing the bus not to start when she had no issues at all before replacing the filters? Months would go by and she would start right up. It's hurricane season here in south Florida and we're close to some really tall trees. If a storm comes, we need to move her. That's a huge part of why we chose to live in a bus. Please advise what else I could try. Thank you!!!

It is most probably an air lock. Some engines, after a filter replacement, need to be primed much like an old hand pump. Once the fuel flow is restored, it should start as it always did. I experienced this with an international straight truck with a 466.

After changing the fuel filter on my t444e it usually takes a couple dead batteries worth of turning over to get the fuel where it needs to be. Grab a battery charger

Oh, and don't be too eager. Let that starter cool down between attempts

I replaced the hand pump. Not it.

When you replaced the filter and water separator, did you fill them first with clean diesel juice?

Sorry, but I had to ask the obvious question.

Capt Squid,- you also asked this question in order to remind noobs (like someone with a blue bus I know) to do this, too.

Thanks.

Hard to imagine that it isnt a priming issue.

x2 for priming issue. I assume there is a bleeder screw, loosen it and pump pump pump until there is fuel coming out of the bleeder screw. I heard it can take a while. In my diesel truck it would take a few minutes, but in a bigger bus, double that?!?!
