Hi guys,
86 GT 5sp
I just noticed it the other day driving - for a half a second or less, the car quit, gauge needles flickered down to zero, and then it came back.
Driving last night, car doesn't want to stay running, runs perfectly fine, then boom, like I shut off the ignition, dies, then comes back to life. Luckily, I was close to home so I let it cool down for 2 mins and limped it home. Letting it idle in my driveway, it would intermittently act like there was no power...it stayed "idling" but it kept shutting off for a split second, then come back to life. I heard my Fuel Pump relay clicking, and then opened the hood and heard my WOT Cutoff relay clicking as well when the car would "miss".
TFI is recently bought, same with coil, wires, blah blah blah, all the normal stuff that usually craps out was replaced when I did my heads/cam build. I've never had an EEC relay problem, so I don't know if these symptoms are normal. All I know is that for my tach to go to zero for the split second - means my coil is temporarily not getting power, and with my WOT A/C Relay clicking, and fuel pump relay clicking, something tells me that a relay or connection further up in the circuit that provides power is intermittently breaking the circuit. Oddly, though, when it would finally die and not idle anymore, the fuel pump was still running as I could hear it (Walbro 255, very audible when car is off), and the A/C WOT Relay would intermittently click every couple seconds, along with the fuel pump relay (and when this clicked, I could hear fuel pump momentarily shut off for the click). Voltage at the AC and Fuel Pump relay is good, I'm not home right now or I'd check the EEC relay.
Aside from EEC relay, what could cause this odd situation?
