I'm installing my scanmaster and an electric fuel pressure gauge (Prosport Evo) on my '87 GN and I'm seeing a weird problem with the gauge where it is flickering - not on and off, but not staying bright. I think I've pretty much ruled the gauge out, putting 12v directly to it works fine, and the gauge is strong and steady.
The weird thing is, when I let the car sit for about 10 minutes and turn the key to acc, the gauge lights up just fine and is strong and constant, but when I start the car it starts to flicker, and does so even if I go back to acc. 10 minutes later it's again fine on acc until I start the car. I've tried several different grounds under the dash, same issue.
The scanmaster works just fine. I'm pulling power from IGN1 in the fuse box for both the scanmaster and the FP gauge. Anyone seen something like this? Thanks!
