Default 98 gmc wont start

Ok guys here go's. HOPING someone can help. This may take awhile. 98 GMC 1500 Z71. Short story, Was driving and it stopped, wouldn't start,ran down batt. called wife, jump it and started, then stopped again. Tried again it started and drove it home and has set for 2 months until $ was available. I have a 95 GMC that did the same thing so i changed the fuel pump on it and it ran fine, so i thought this was the problem on the 98. Put in new fuel pump and tank, nothing, check for fire nothing, new crank sensor, nothing plus no fire. Repalced ICM, now we have fire (spark) but no fuel and can not hear pump run. Someone mention it could be in lockout mode, if so how do i get that corrected.. ANY HELP IS WELCOME....THANK FOLKS
