The pump could be defective. Or the power may not be getting to the pump. Check the pump fuse and relay to start with.
Bad fuel pump?
Does the fuel pump work? Check that. yes.
Make sure you have voltage at the pump. If you do then the new pump is defective. If not, the fuse is blown or the fuel pump relay is bad. Where is relay?
Either the fuel filter is clogged or the fuel pump is defective, even if it is a new pump.
yes you can just change intake but then you have to figure out a new way to get fuel to it stock pump wont work
yes if you need new fuel pump, the engine is not getting fuel. therefore no fuel equals engine wont run
There are a few possibilities. First off that new fuel pump might be defective. You would not be the first one to buy a defective brand-new part. Secondly the fuel pump fuse or fuel pump relay may be defective. And thirdly that fuel filter may be clogged.
Check that the 'new' fuel pump is actually pumping.
Do you have power at the fuel pump relay test connection. do you have fuel at the schrader valve on the fuel rail.
Did you change the fuel filter? Have you checked the fuel pressure regulator?
It is unnecessary to bleed the lines after installing a new fuel pump. The fuel pump will pump all the air out of the fuel lines and start to work properly without any bleeding. Just install a new fuel pump and start the engine.
if you're fuel pump is bad it will most likely die and wont start or wont run very long, or it will run but will seem like its out of gas, replace the filter first its a lot cheaper then the pump, if its not that then its the pump
