01SAN fuel pump circuit needed

Recently an intermittent problem developed to engine can crank but don't fire,      a couple weeks ago,the engine had 2,3 times die when towed a rider, after that, seems no problem and back to trailer But I think that there should be some thing wrong , next week ,try to run the engine on trailer ,don't fire at all , find that no spark and no input voltage on primary coil , and found there are no power to both fuel pump relay, obvious ,there are relations , jumping a +12v to one of the relay’s pin 86, some high frequency noise can be heard from the HV coil ,start the engine ,it runs as normal , by this way, the keypad can't stop the engine ,need disconnect +12v ,can't trace by one day where the positive 12v of the coil of relay come from, this +12v supply the fuel pump relay and spark circuit and controlled by keypad PME box (the breaker box on the kicking board) ,once keypad "start''ed, it exist, had read some topic about fuel pump relay circuit, DanieIC explained well in some aspect, but my case seems not the same ,any though? any body know where can get the fuel pump circuit for EFI GT-40 on 01 SAN ?
