V 10 spins will not crank.

1997..first time ever will not crank. Usually just touch key and fires right off. Now leading up.. But don't see how this could be the problem. Drove up on some blocks to gain access to install new Hellwig sway bar. Where the L bracket on drivers side attaches on the inside of the frame there are two fuel lines going forward. Was very carefull in not disturbing them to attach top bolt on bracket. Got finished and tried to crank to drive off the lifting blocks. Just spins. Fuel pump fuse OK, removed passenger side panel to check emergency fuel shutoff, OK. Just noticed something else as trying all things, but I can shift the gear shift lever to any position and the starter will spin. I thought would only start in Park?? Old Fords had a shifter problem that you had to lift up on the shift lever to get to crank. Something is not allowing some sensor to not allow to crank. Other than unplugging fuel filter and turning over to see if fuel flow, how can I test fuel pump. Any and all ideas appreciated.

I would say a connector got knocked loose during the installation of the new sway bar.
A wiring harness could have got pinched? Check the fuse links adjacent to the starter relay on the firewall. Follow the chassis battery to it as I am not sure where it is located on your rig.
Does the dash warning lights come on?
The engine should only crank in park or neutral.

Tank is at least 90% full. As mentioned in first post, emergency fuel shutoff has not tripped. Never said I disconnected fuel lines?

OK, can hear fuel pump whirring when key is turned to first position, so think I can rule fuel flow is not the problem. Thinking more now has to do with transmission position. Tried jiggling wire harness that goes into side of xmission where shifter cable comes down. Might try jacking rear up to get off blocks later and see if maybe a slight roll of drive shaft it will get something back in sync if no other suggestions. If I do take off the blocks, cannot crawl back under without jacking up again, so not next option.

Great thought. Sometimes the obvious we overlook.

So this occurred after disconnecting the fuel lines. My thoughts are to check the connections to eliminate air possibilities, also I owned a Thunderbird that had a fuel shut off switch that killed the power to

the fuel pump if the vehicle experienced an impact. A small rear end collision and the fuel pump shut off. There is a reset button somewhere. That was a 1985. The possibilities that the fuel pump died at this

time seem odd. Time to get a wiring diagram of the chassis and look for that shut off switch IF there is one. A clogged fuel filter, one that is hidden inside of the frame rails is also possible. Striking the coach

with a hammer to install parts may set off a switch if it is weak. IMHO.

No. The engine is cranking over.

Are you saying that the starter spins but it won't engage the flywheel?
