Just Got A MK3

Codelicious · 02-10-2010, 03:44 AM

So I'v been having problems with my 1986.5 MKIII reving itself up and we thought it was just a vacuum leak.

Tonight when I got home I ran a diagnostic lke cygnusx1.net says to and it came up with the code 43.

Code 43:

Starter Signal

Diagnosis - No "STA" signal to ECU until engine speed reaches 800rpm with vehicle not moving.

Trouble Area
- Ignition switch circuit
- Ignition switch
- ECU

Anyone ran into this problem? I hardly know anything about cars so I don't even know where to start... maybe my $800 Supra was $800 for a reason.. lol
