Fuel Pump gone?
I have an MPFI EA S-Pack 08/89, and its confusing the hell out of me, but I think I have narrowed it down to the fuel pump. The last two months the engine has been starting terrifically when it is cold. After it warms up it starts runs like crap for about 5 seconds then stalls, but then on the second start it starts perfectly. Just yesterday when I got home from shopping I stopped the engine to unpack it, then went to put it in the garage, it started went to reverse back then stalled. Went to start it again then the same thing. I thought leaving it for a couple of minutes would help but to no avail. I've tested the relays and I've tested the fuel pump connector and there is power going to the pump.
