sec500 starts but dies

[Baracuddda]

Hello all
just bought a 1988 SEC500 it starts everytime but dies immediately, sometimes starts and drives for miles no problem. Electrics are ok .
Could it be the fuel pump relay ? fuel pump ? What is OVP relay ?

Regards
Bara

OVP stand for "Over Voltage Protection Relay". The OVP has its own fuse. If that fuse is blown, the ECU doest not get the correct voltage and that can cause your problem. normally the OVP is located next to the ECU
