okay guys... before winter I was driving home to.put my car away and the car just died....I checked and no fuel pressure...so I figured the pump went out....I bought a pump from full throttle and it still had no pressure...battery is good, I unplugged my hotwire relay and plugged it in like stock to see if the.relay was bad...still not pressure...any ideas...and I dont here the pump eithwr
 
Can you hear the pump prime? Pump relay bad? Hot wired? Check connection at ALT. Getting power to the pump?
 
Same thing happened to me before. Check the orange ECM wire going to the battery and make sure it's not broken. Does the scanmaster power up?
 
I cant hear the pump prime, it was hot wired, however I unplugged the hotwire relay and plugged the pump into the factory plug so I could bypass the hotwire relay in case its bad, and there is power at the alternator
 
Check for voltage at the pump harness, its possible to get a new bad pump.
 
okay I disconnect the plug for the pump and put a test light up to each of the three pins on the vehicle side...the middle pins lights the test light, I put dirrect power to the pump side and it kicks the pump on when I touch the positive to the outter pin
 
There's a signal wire that closes the relay for the fuel pump power. It's attatched to the relay on the pass fender, gray with a black stripe if memory serves. Obviously, if your pump comes on with 12v applied it's not the pump but the circuit. If the relay's not getting the signal to close then neither the hot wire or the stock pump feed will work. Probe that wire, then turn on the key and see if it has voltage.
