Jeep Cherokee Laredo

What cause a 1991 model Laredo Cherokee to take longer time cranking before it will start?

My 1987 jeep had a similar problem. the wire leading down to the crank sensor (necessary for the engine to develop spark) was damp and grounding against the firewall. Tied it slightly away from the firewall w/ a tiewrap, and never had problem again (previously the dealer had replaced the crank sensor twice without the problem correcting itself)
