So got a friends truck I'm working on, its a 98.5 24V auto 3500 dually. When I got it towed to my house I was told it stalled a few times and now would not start, cryptic I know.

Put key in and light on dash come on and turn key and nothing. Check batteries and cables and all look clean and tight. Went to starter and the exciter wire never gets power when key is tuned.....hmmm. Swapped relay in box under hood and no change. Jumped power to exciter post on starter and it turned over. So figured it was neutral/park safety switch. Checked it and wiring looked ok than found diagram and grounded the brown wire disabling the switch and same result, wont turn over. I then tried starting it in neutral and it turned over fine. Whatever its now turning over but wont start.

I hit it with a little ether and it fired right up. Now I know its fuel related. Checked around and the "lift" pump should be getting power when key is turned on and I have verified it is getting power but does not make a sound. So I think thats my 1st issue. Thoughts?

Now my reading sasy there are many issues with stock lift pump. Should I replace it with an after market one and if so which one?

Thanks!

I think FASS makes and external mount pump, for just such an occasion.
