99 problem & tahoe is 1

[Hpb]

​

Hello all ,, i have a 1999 tahoe lt 5.7 2wd. Been racking my head for couple days & im bsf on this thing.. truck started & been running great, then it started & quit. Checked the fuel pump ( new) no power from the fuse box to the relay (i did jump it & nothing ,ran hotwire to pump ) & but i do have power to the fuses under the hood. lost spark also. Any ideas where to go from here besides the scrapyard for this old turd... Only codes that have ever popped up was 1133 & 1153 ,i know it needs 02s has for couple yrs. Not sure if its an indicator to those who might have idea on my issues ,but when the truck was sitting turned off ,sometimes the electric locks would start clicking like the lock button was being activated....im kinda thinking ignition assembly but not sure. .. thanks Pete
