If you have voltage across the fuse then the next place to look is the fuel pump relay. Based on no voltage on pin 1 of the FPCM, I would start by checking to make sure fuse F56 (30A) is in working order, as the power supply begins here. Hey Flexmood! Sorry to hear you’re having troubles with your Flex. Of course common sense prevails, do not do this if you don’t know what you’re doing with electrical and always make sure the key is off. Obviously if you’re under warranty I would not suggest this. I know a lot of you are handy and can do this mod yourselves. I always a small tool kit anyways which has the 7mm socket needed to remove that C pillar panel so I shouldn’t have to pay for a tow again. The fuel pump will be ‘on’ any time the key is on.Īnyways, I plan on keeping my jumpers in the glove box. Jumping those connections will turn on the fuel pump allowing you to start the engine. 1 and 5 get jumped together and 4 and 8 get jumped together. If your colours vary, it is the 4 large wire gauge pins numbers 1,4,5,8. YEL/GRY and VIO/GRN - this is the power circuit WHT/TAN and BLK/GRN - this is the ground circuit The wires you want to connect together are: Perhaps it is just an on/off switch as the module is powered at all times when key on. Also I’m not entirely sure what relation the pcm has to this module but they are connected. I do not recommend keeping it permanently bypassed as in a collision the restraints module can actually turn off the fuel pump.
