I have a 85 k100 I just bought a 91 k100 when I turn the key on on the 91 I hear the fuel pump run on the 85 when I turn the key on I don't hear it run however it starts and runs fine (alittle harder starting than the 91) question is are they different systems or should I hear the pump on the 85 if so any ideas what might be wrong thanks
