Question about 2002 Pontiac Aztek
Posted by Anonymous on
The electric fuel pump is controlled by a relay in the fusebox.
It normally only goes on for a few seconds, and then if the alternator does not signal the engine is running, the relay is supposed to shut the pump off. But you can shunt the secondary wires of the relay to keep it on if you want to check fuel pressure.
Try some starting fluid spray to make sure the ignition is good.
It will at least sputter on the spray, if there is spark.
Here is a picture of an Aztek fuel pump relay:
