Hello. My name is ***** ***** I will be helping you today.

You mean the passlock system? Do you not have the original key?

Customer: replied 1 year ago.
we have the original key but my husband replased the fuel lines that go to the spider and to do this he unhooked the battery. Did the repair and the truck wouldn,t crank. Turned on the key let it sit for 10 min and restarted and it would crank. The security light came on again . redid the steps but now it will not crank at all.

OK. Does he have a multimeter? You probably just need to relearn the key if anything. You would have to do that anyway to bypass it (just using a resistor instead of the key)
