The fuse only blows for 1/2 the injectors (2,3,5,8). The other half is always fine. We tried a second set of injectors and they also pop the same fuse. We also tried changing the PCM and it didn't do anything. Before it ran fine with no problems. Any ideas on what else to check. As for the MIL, it only comes up for the injectors after the fuse pops.

if you have injectors 2,3,5,8 unplugged will it still burn the fuse? if it does then the problem will be in the wiring that leads to those injectors quite likely a short to ground, check the harness to see if u find the problem, i can look at the diagrams if u cant figure it out.
