Have fuel ... now ABS light is on ... no codes

I just replaced the fuel pump and sending unit again today. It has only been 3 months. I can hear the fuel pump run when the key is turned on.

I am not getting any fuel pressure at the test port.

I also replaced the fuel filter while it was all apart.

Tomorrow I may remove the filter line to see if fuel is pumping there.

What would cause no pressure?

Thank you.

Some sending units have problem with the flexible fuel feed hose (connects from pump outlet to underside of sending unit bulkhead) popping loose, or in my case, the 'cap' that fits on top of the fuel pump can have a bad seal/grommet and fuel just leaks past this fitting. Did you change the strainer?

Ok, I had my idiot moment. I guess that 2 gallons of gas when the car is still on jack stands is not enough.

It is running now.


Anyone know what would cause the ABS light to come on after changing the fuel pump and sending units ?

There are no diagnostic codes.

Thank you,

Danger Will Robinson! Don't ever let that pump go dry like that - seriously, it cooks the electric pumps.

Sometimes depending on where you put your jack you might have fouled up the alignment of the sensor. Since you have rear drum brakes, your rear ABS I think are on the differential. Sometimes torqueing the car right or left throws these off. See if cleaning them will help. All kinds of road gunk and brake lining fragments (esp. on the front ones) will set the light off.

Running dry was not the intention, as I addded gas, after changing the pump and sending unit.

Jack was on the frame rail, it may have done something when I lowering it.
