So im running into some electrical problems with my 180. Leads me to think a bad ground, but im not sure where to look.

1: fuel pump wiring went. got around that by hardwiring it so i could drive the rest of the season.
2: Speedo plays dead sometimes, usually after 10 min of driving it goes away.
3: Odometer stopped working. not such a bad thing.
4: Starter stopped working. just put a fresh one in, just clicks.
5: When i step on the breaks now, the arrow for left signal comes on, not the signal, just the little green arrow :confused:

Car had a ground kit on it when i bought it back in '08. took it off during battery relocation, ran fine for 2 years.

Guessing its ECU or an engine ground? As i said, not the most experienced with electrical problems. Thanks for the help in advance.

Common issues with inadequate grounding... It would be the easiest, and possibly the cheapest, so it's a good starting point.

Where are the grounding points?

Just make sure every ground in the harness has a good connection, and then ground out each major component to the chassis: block, head, valve cover, intake manifold, transmission. Make sure your battery ground is nice and clean and has good connection as well. Even if this doesn't solve your problem, it's a necessary modification.
