I have a 91 240sx w/ sr20det swap. Has sds engine managment. When im tryin to crank over the motor the altenator fuse keeps poppin(75amp grey) wondering if anyone has had this happen before and any clues on fixin. Also is it possible for an injector to be locked wide open because 2 cylinders are flooding with fuel but i see no individual injector duty cycle adjustments on then sds programmer. Any advice would be helpful. Thanks

 

You probably reversed the starter signal wire and alternator power wire.

The starter and alternator both have nuts that hold on single thick wires. When you try to turn over the engine instead of the starter getting the start voltage all the power goes straight to the alternator circuit and pops the fuse.

 

ill give it a try, thanks

 

isn't that fuse suppose to be a 100amp. at least my s14 is.

 

nope 75. gray. what color is your 100?
