7.5amp fuse blowing on the injectors. 95--3.4
 
Need help. My sons 95 3.4 is blowing the passages side fuse for the injectors. Had new injectors put in and a new pmc.
Not sure where to check .. has anyone had the problem before?
Thanks

do they blow immediately when the car turns on? or when under throttle?

if its immediate i'd unplug all the injectors (or at least the side that is cause the problems)
with the key off plug one in and turn the key on to see if it blows the fuse. when you find the culprit you can diagnose it further.

could be a short on the harness. the short may not have occurred until you drive it some and the vibration caused the short. not sure, but poosible.

it just occurred to me that if the short is in the harness and you move the harness a little it may resolve the short or at least until it finds itself again.

but hopefully it will be pretty straight forward.
