ok so i;m having a few wiring problems

1. Guage cluster fuse blows when car is under aceleration - **engine ground?**

2. Engine feels lik theirs a Maf problem but tried two mafs, acelerates smoothe and feels if theirs power if i press the gas lightley but bogs down and looses power when accelerator is flored it constantly hits empty spots in the rev rancge where their are no accelerative properties **-o2 sensor? improper adjusted distributor? knock sensor sensing knocking and retarding the timing ?**

Sometimes car wont start because fuel pump relay dosnt turn on the pump
