[ATTACH]38995[/ATTACH]I have been off this site for a while, other distractions. I'm back to working on my Z's since I retired. I have a '80 280ZX that's been sitting for 2 years that I bought mainly for the engine. After checking the engine over, I threw a battery in it and got it started. Tough to start and won't take fuel while cold. I suspect the cold start injector. The main problem I'm having is the fuel pump runs half the time when the key is turn on. I installed a temp ignition switch to see if that was the problem. It did the same thing. I'm thinking it is a fuel pump relay. After checking the engine bay breaker box and FSM, there are 2 relays, it seems to me there is a breaker missing. See the attached photos. So far I have replaced: distributor cap, rotor, plugs, plug wires and ignition switch. Does anyone have any ideas on the fuel pump problem? And, the fuel pump relays #2 on ebay show a single unit where as the FSM shows an elongated relay. Any suggestions, pictures or input?

The relay that usually causes the problem in the zx is the one behind the glove box.

Its the green one, closest to the firewall of the three mounted there. Check to see if any moisture has gotten in there and corroded the connections. Easiest to access with the glovebox liner removed.

Also, reseat the ecu connections a few times to clean up those connections (behind the left drivers side kick panel) the fuel pump relay gets its signal from this connector.

Thanks for the input. Looks like I'll have to wait a couple of days to check it out. It seems to be snowing here in Colorado, east of the Springs at this time. .
