efi fuse keeps popping?

2genfun · 04-11-2012, 02:53 AM

so my 88 turbo has been running very well and all i have done today was swap some 550cc and new clips in...now anytime i hit over 50% throttle the efi fuse keeps blowing up on me. i can swap a new one in and drive normal. In neutral it'll rev with some misfire but if ur driving and put a big load on the engine = popped fuse...

Well, then grab a meter and start testing for the short.... Start with testing the injectors.

i dont want to be the odd ball question but your tag says 7mgte, wouldent you do more harm than good whith 550cc injectors if not combined whith the additonal hardware requierd to run them properly ( more fuel needs more air)
