If you don't fall, you're not trying hard enough.
If it doesn't hurt.. Go Bigger. Tubing Sucks. |

Don't those leads mount to the pump with screw terminals on the bottom of the pump? I have never had mine off but some time in it's past the pump was changed by the dealer= top of picture in the middle are the connections

I am replacing my LPFP today, I will also be installing a inline filter.
My new pump has a different connector on it than factory, Does anyone have the part number of the mating connector? Or what is the best way to connect the new pump to the old harness? |

You can jump the fuel pumps to run continually to help trouble shoot.
What fuel pressure are you getting when key is turned on? Here is a picture of the jumper for the pumps

Maybe your low pressure pump has died? Give it direct 12V feed and see if it runs or at least verify it has 12V when the key is turned on. Remember you will only have 12V at the pump for 3 seconds after the key is turned on to pressurize the system. After 3 seconds if your engine is not running the pump is designed to shut off.in normal operation.

Short an simple:
Motor won't fire. Motor will turn over. Replaced the low pressure fuel pump. Try swapping the relays, pump relay and computer relay. I'm getting power to the relays but no power to the low pressure pump. Kill switch is correct. Fuses are good. Strong battery. I cannot hear the pump turn on during ingnition. What is the deal!! |
