Fuel system messed up
 

I was having power issues and when i put gas pedal down it bogged out so i thought fuel filter or pump . So i replaced so far pump, regulator and the one on the fuel rail and the filter. Now it wont start without the aid of spray starter. It doesent run. Can someone help?

Year of car and engine type?

2002 2.4 le

Does the fuel connection have a quick disconnect at the fuel rail. If so check for fuel flow. The pump will only work when engine is cranking or running.

A bad crank/cam sensor can cause starting issues.

Off chance make sure the EGR valve is not stuck open.How is the ign spark?

Have you checked for any pending trouble codes?

I can't check for trouble codes because I unplugged the battery.

Not getting enough power to my fuel pump
 

after replacing just about every component in my fuel system im not getting enough power to the pump. The fuel only drizzles out when i unplugged it from the fuel rail.

Electrical power at pump?

Make sure the negative wire to the pump has a good ground to chassis. White/Black wire.

Check for battery or alternator voltage at the positive wire. Blue/Black.

there is only 11.7 volts going to the blue /black

figured it out! As it turns out I found that I misplaced an o-ring when doing the pump. It was hard to discover. Thanks for all your help.

Thanks for posting back with the fix.
