So I've been having starting issues for a while in my 89 2.8. Decided to do some clean up in the engine today and verify all vac lines (work has been crazy so i havent had time to touch it) and i noticed that the battery ground is going to the fender instead of the block. What size and length of wire do I need to replace it?

 

Post a pic...

 

post a pic of what? im just trying to figure out what the length of the negative cable is off of the battery and where it is suppose to connect to

 

IIRC you should have two cables coming off the negative terminal a smaller one that may go to the fender and a larger one that goes to the motor

 

A pic of your battery cable going to the fender apron. I've never seen that on a thirdgen.
It's supposed to go to a cylinder head or block. There might be a small pigtail going to the fender apron, but that is not the main connection point...

 

yeah, the previous owner put it under the washer reservoir and I just saw it. That is probably why it's had hard starting issues since I got it. it's most definitely the 4 gauge on the fender. it should connect to the block, right behind the AC Compressor right?

 

You need this. The big end goes to the block. Not to any brackets bolted to the block, not to the heads, to the block itself. The little end goes to the metal that is the radiator support. Not to the fender or anywhere else.
