My young blokes 120 d4d wouldnt start after fuel filter change.
i had a look, wire had been pulled out of the plug going into back of the pump.
Fixed that, pumped the filter housing primer while he cranked and it finally went.
He took it out on the highway and she died after 10k.
I went to help him out and it took alot of pumping and cranking but got it going.
This morning it wouldnt start.
Its been drinking fuel too so something is up.
Any ideas guys?

No fuel leak from anywhere?

What was the reason for changing the filter?
Was it starving for fuel or same problem you’re now having.
My 150 has a filter between the tanks. It does all the work, engine bay filter is secondary.
Presume the 120 is the same.

No fuel leak.
Had a scan tool hooked up came up with
fuel pump open circuit
We were also told it could be a solenoid at the rear filter?
We used bullet crimp connectors between the fuel pump solenoid plug and the loom.
Will solder these and try again.
The fuel filter was changed as a routine maintenance as was the engine oil.
Anyone got clues as to the bad fuel consumption, were talking nearly double.

I have read of an issue with fuel filters having a convex area where the series of holes are drilled around which minimises fuel flow as there is then less clearance and you can get ones that are convex or flat. I have run both on mine and don't seem to have had the issue but maybe worth considering. Got the parts co to open up 3 different brands and they were intrigued by it too.
