Pumps dont prime when key is turned on Have two Walbro 255 pumps in the tank. Car ran perfectly fine when I left for school. Has just been sitting while i've been gone. Went home last week and noticed when I turned the key to the On position you no longer hear the pumps priming. Obviously the car wont start as theres no fuel pressure but it turns over just fine. Anybody have an idea of where to start looking? Something like a schematic so I can check power down the line from the source all the way back to the pumps themselves. 98 T/A with a 99+ engine harness

Checked the relay and I have power to the relay. No power at the pumps. Gave the pumps a seperate 12v power and they ran as I expected them too. What's in line between the relay and the pumps all the way in the back I should check next? I've been searching for wiring diagrams and schematics with no luck

im assuming you have a hotwire kit? If so check the rely, as mine was bad right out of the bag. Otherwise check all the stupid things like fuses, bad grounds.
