I have an 04 colorado. I just put a new fuel pump and filter in it. Now it wont start I drained all the old gas out and put fresh gas in. I hear the fuel pump working and checked to see if I had fuel pressure in the fuel rail and plenty of pressure is persent. If i put starting fluid in the intake it will start brifely then die. It ran fine with no problems before the fuel pump died what should my next step be.

Your going to need to drain everything from the gas tank and put in fresh gas. If it cranks over, it will start. The electric fuel pump in tank will pump the remainder of the old gas into a container if you disconnect the fuel line at the engine and run the line into the container. Then hook the line back up and start your engine.

Check fuel filter for blockages?

I bet it's the gas. After some time the gas will no longer be volatile enough to start the car. Try draining all the fuel and putting in some fresh gas. Remember, when you try to start it again you'll need to get the new gas through the pump and lines before it will start. Also, check the condition of the injectors. Old gas can start to break down and build up a film that could be on your injectors (or clog your fuel filter- better check that too). Hope this helps.

new parts ?? why ,take the sender unit out and clean the gauze filter in the bottom and depending how much fuel in tank top it up with some fresh ,one engine warms up a bit it will run on the old fuel ,abiet smoke a bit maybe and be hard to start but it will run to get it home ,no some fresh fuel and i think it will be ok ,old fords never die remember

Fuel pressure for your car should be 50/60 psi you probably need a new fuel pump.

If it has not been started in a year, you might want to either drain the old gas out (because gas can go bad) and put fresh gas in and try again, or go to an auto parts store and pick up some fuel treatment/restoration. The treatment will NOT be a permanent fix,but should allow the car to start. Now the bad news. It could be the fuel pump, whci is a hard thing to change. To know for certain if it is the fuel pump, here's what you do:
Get in like you are going to start the car, but leave the driver door open, there needs to be silence.
Turn the key to just before the engine would start (the radio comes on and the AC starts blowing, but the engine is off)
Listen carefully, if the fuel pump is working properly, you should hear a hum coming from the back end of the car by the fuel tank. If you hear this hum, that means that the pump was turned on and primed. If you do not hear the hum, chances are that the fuel pump is shot.

I would recommend changing the gas first before you try to start it again, because if the fuel pump is good and the gas is bad, that bad gas is being shot into your engine.

I hope this helps. good luck

I would get some fresh gas, about 2 gallons in the tank, a couple cans of dry gas, to soak up the water, and get that thing fired up and drive it till it is empty. Then put in some fresh gas, and another can of dry gas, by then , you should have a nice clean engine and a clean tank. If you have to pull the air horn off and squirt some fuel into the throttle, do it, just to get it going. Once it starts, don't let it quit if you can help it, keep revving it and drive it. It will sput and cough bu it should be ok. The fuel pump should be fine and the filter will clean itself out of the water. Hope this helps.

find the buzzing noise...likely its the fuel pump relay.

With a new plug and fresh gas it should start. Check to make sure there isn't a kill switch turned off or that the gas petcock from the tank to the carb is on.

How did you check the fuel filter? Disconnecting it from the fuel line that goes to the carb is the best way, making sure the gas is turned on under the tank. Bleed off a little gas into a can or something just to make sure the filter isn't plugged.

The last thing I'd do is take off the air filter and spray a little starting fluid in the carb. It may start and run several times if there is old gas in there somewhere. Remember the bowl on the carb is probably still full of old gas. After some fresh fuel reaches the plug it should start and continue to run.

(You might drain the bowl on the carb of ols gas before you go any further)

Good luck!

did you try the fuel filter
