Thats the the SRS (AKA Air bag sensor) It just simply told the ecu that you bin in a colision and it shut the system off,Take off the battery to reset it join the wires back Properly and zip tie em out the way then connect the battery back and go for goal....

You would go to the Fuel ECU and just run 12 v straight to the pump from ignition power. BTW make sure the battery is disconnected when you repair those wire. Yellow Means airbags, also discharge the capacitors to be safe.

-replace fuel filter
-Borrow an ECU to test

the car already has the 12v mod yes its crossing the green wire w. the black and red wire, the car died on my buddy one day. before it died it had the 12v mod already and was running fine. now those yellow wires is wat i see wrong w the car i checked the fuse box in the engine bay and some large fuses top is broken but fuse looks not broken still, so w that being said i did everything 12 mod, connected back those yellow wires, unpluged and pluged the battery back in and i still cant hear the fuel pump working at all. so im guessing its the main ecu, is there a way to test if the ecu is working?

ive had the FP ecu bypassed for quite sometime now as well and one day my car would not start... fuel pump would not come on. but when i jumped the fp and +b in the diagnostic port the fuel pump came back on and started...

pulled codes? sometimes it doesnt show one but there is. in the instance i had described above my CEL wan not on but it threw a code for my fuel pump.
