fuel purge after filter change

[blackestate]

Ok, a friend has changed his fuel filters, the truck did not run before, he bought it that way.
Still will not start, so he took the cap back off of the upper fuel filter and it is empty.
So he filled it with the key, while the cap was off, then it still would not start, and the filter was empty again.

So how does the air purge work on this thing? could that be his issue?
Any other ideas?

Thanks

He needs to make sure that he got the lower filter installed properly. If it isn't the truck will not start. Is the pump coming on when the key is turned on? Might have something else going on but I would start there first.

I will have him check that, The pump is working,because with the cap off he can fill the filter bowl. But it may not be enough?

troubleshooting a no start condition link is in my signature. Gives you a check list to go thru

I found that and was looking at it earlier. Lots of stuff to check. So I will pass it to him and help him If I can.
The biggest issue right now is the fuel draining out of the upper filter. I do not think it is getting fuel to the injectors. But we will start the process.
