2000 Mazda 626 2.5L Fuel Pump Problem

[JRidenour79]

I have a 2000 Mazda 626 2.5L. I recently pulled it up on a set of ramps, changed the Harmonic Balancer, and tried to start it. It was running fine before I changed the balancer. Now it will not start. It will crank, however the fuel pump does not appear to be working. I pulled the fuel line off the Engine Side of the Filter and when the key is turned on no fuel comes out.

I hooked it up to a computer at home and their are no Codes, and all fuses and relays appear to be working fine.

What could this be? Does anyone know?

Did you disconnect any sensors while removing the balancer?? CK for power and ground at the pump itself. Disconnect fuel line at pump and see if it comes out, maybe filter is clogged.

I didnt disconnect any sensors, however I cant seem to find the wires leading to the fuel pump. I have looked for a diagram online but can not find anything.

Try and get you hands on a haynes manual.

Ok. I had thought about getting a Haynes. Ill grab one tomorrow

Have you ever had any hard starting issues with the car in the past?? Do you have any starting fluid? If you do try and see if the car can start with that. If it does hold down the gas pedal. If its a small enough clog, the pressure can build up just enough from the pump which could push it out of the way. Also I must ask this, is the gas near empty? Can you hear the pump turn on if you are near it? Also if you can find the connector at the pump, disconnect it and directly feed battery voltage to the pump for a second to see if it turns on.

I tried starter fluid, no effect. No starting problems in the past. Vehicle was running fine till I pulled it up on the ramps. It has a lottle over half a tank of fuel in it and was running excellent till now.
