How does a bad ground effect the EFI fuse? I have a 93 3.0 and it's blowing the EFI with every attempt at starting.
O2 sensors wires are fine. Replaced Relays, new fuel pump, disconnected AFM and VSV. No change.
Only blows when starting and not in the on position. I'm extremely frustrated. Swapped the Computer and no change.
I'm going nuts. can't find anything wrong but as soon as you turn the key and the starter is turning it blows the EFI FUSE.
any ideas or help would be greatly appreciated. Thanks in advance.

Did you recently replace a part before this started happening? Had this similar thing happen when I replaced my alternator.
Turns out the new part or “rebuilt oem” alternator purchased on eBay was poorly rebuilt from the person who purchased it from and it kept blowing that 30 amp fuse every single time as well. Got the doofus to send out a total of 3 different alternators out and they all gave different problems.
Got a proper rebuilt replacement from Autozone and haven’t had any problem since. My guess was internal shorting in the first alternator. Best of luck to you.
