ecm1 is injectors not fuel pump ecm-b is fuel pump its more likely to be a faulty relay for the injectors, it would be a similiar design to this
this is for the fuel system, relay for the injector is nearly the same.
Check fuel pressure. Have you replaced the fuel filter on schedule? Verify that the fuel pump is getting power. Power goes through an in-line fuse, then the fuel pump relay or the oil pressure sensor. (The relay bypasses the oil pressure sensor while the engine starts, but fuel pump power goes through the sensor during normal run operation. If you lose oil pressure, the fuel pump is shut off to protect the engine.) On four-cylinder models, the fuse is in the fuse block (E PUMP 10) The fuel injectors are connected to the ECM fuse on one side and straight to the engine computer on the other side. Check the connectors and wiring, especially at the injector.
Need more info.......It could be the injectors are not pulsating...Check to see if it is spraying fuel from the injectors....If not it should be a clogged fuel filter or a fuel pump....It is almost definite though that it is the fuel pump/sending unit in the tank ...IF it is not spraying from injectors....
Disconnect battery remove main fuel line going in the fuel filter under vehicle frame at drivers side..with drain pan under it of course...Reconnect battery turn engine over and watch for fuel...
You will need an assistant...Most people think fuel is under great pressure but it is not.....If everything works the fuel will come out in a stream...But it wont come out like a bullet...
If fuel comes out Fuel pump in tank is good...Then your problem is at the injectors ...I would change the filter of course anyway...unless you just have...You will see rusty dirt come out of it if it is clogged...It is always good to change fuel filter every 15,ooo....Todays fuel is terrible...I would first check or swap fuel relay with a new relay or identical relay in fuse power block ...Make sure they are all good....................What engine and how many miles ? Hope this helps....Metalpoet
It could be the fuel filter or the fuel pump or the regulatur or the main injector if you have throttle body injection . Start with the fuel filter if you have never changed it its likely time you did . Then when you have that off turn the fuel pump on and see how much fuel its pumping you should get 4 or 5 ounces in 5 seconds at about 60 PSI but if you get the volume you don't need to worry about the PSI
It could be the fuel pump or the pump relay or fuse. It could be the fuel filter or the gas lines. If they all check out, it may be the fuel injectors. Start with the pump and make sure gas goes to the filter, through the filter, to the injectors. You'll find your problem.
Fuel filter stopped up, fuel pump relay needs to be checked and replaced or fuel pump itself is bad. Have some get down on their knees at the side of your car and turn on the ignition switch, can you should be able to hear the pump pulse in the tank, if not replace relay and filter first. Pump is inside tank.
