Charlie. You have replaced the ECM on your van?.
Kedwin,, Your problem is, the computer on that 3.3 L.
Need to be programed with the VIN nember of your car.
The Antitheft System will disable the injectors due a incorrect VIN, Bucause the body computer is not recieve the correct pasword between 5 seconds after start up.
YOU have 2 options. 1 get a ALOHA Smith. some of they have the computer required to program ECMs.
The other option is: Get a new ECM from the dealer, They will program if ask for that.
NOTE:::::: Other way is . Put the body control module with the computer from the same car.
OK... I hope this work for yours.

the relay and fuse are in the power distribution box under the hood. as far a by pass you still can use an aftermarket electric pump ,however the cost will be about the same as re3moving the old pump in the tank if that is the cause in the first place. if all you need is the relay replaced then i'm sure that the pump is still good. if the pump is bad then make sure if you by pass the in tank pump that the new under hood electric pump has enough pressure to give the needed gpm(gallons per minute) required for your system and that if wired into the current fuel circuit that you dissconnect the wire harness to your tank pump
SOURCE: how to get the fuel pump out of the gas tank on a
you have one or two options you can slide the bed off of the frame enough to gain acess to the top of the fuel tank or you can drop the tank if you drop the tank its better if its not full of gas makes for easier handiling either way once you get access to the top of the tank you will have to use a straight edge and a hammer in order to release the locking tab on the pump once the tab is free you will be able to pull the pump out of the tank. reverse the process in order to reinstall.
