Okay, today I finally got around to installing a new fuel pump in my Festiva. In addition, I cleaned the fuel pump relay really well and put dielectric grease on all the connectors. I was having intermittent starting problems, and ascertained that the fuel pump was going bad. I had strong spark, so I sprayed a little carb cleaner in the throttle body and it started and ran for about 3 to 5 seconds. This pretty much says the fuel delivery system was at fault.
I paid $30 shipped for a brand new fuel pump, with sock and new hardware from Ebay. It was a perfect match to the factory Denso pump.
Tools required: #2 philips screw driver, slotted screw driver, needle nose pliers, and slip joint pliers, and spray lube (makes hose removal and install much easier)
With no further ado, here are the pics with descriptions above each picture.
I removed the fuel pump relay under the drivers side dash and ran the car til it died. Then I just cranked it for about 5 to 7 seconds to relieve the fuel pressure. Then disconnect the negative terminal for safety.
Flip the rear seats up and forward to expose the carpet underneath.
Remove the 8 or so snap clips holding down the carpet to expose the fuel pump housing.
Disconnect the connector and remove screws securing cover. Also remove rubber grommet to get cover out of the way. Disconnect the two fuel lines from pump outlet and return line to tank. Remove the whole assembly, it was tricky because you don't want to bend the sending unit arm. Be careful trying to remove the pump, I had to play with it to finally get it out.
Make sure the two pumps are identical. I should have paid more attention to the way the sock and the hold down clamp on the pump was installed. I had to figure it out but its pretty straight forward.
See that little silver piece, it has to be removed from the new pump for the rubber grommet piece to sit right. This is one of the reasons you have to pay attention and somewhat memorize how everything is secured prior to removal.
I also almost forgot this piece that goes onto the new pump assembly. You gotta take it off the old pump. I believe it helps seal the pump from bleeding down.
There is a cup and O ring in the area that the pump pushes onto the whole assembly. Make sure these two are still there and not on the old pump. I should've taken a picture of it but didn't. This is the new pump installed into the sending unit and housing.
Reinstalling is easy, except its kinda tricky getting the sending unit and sock into the little hole. I found it easiest to install the sending unit in first and then just working the sock into the tank. Now secure the whole assembly with the 8 or so screws. Make sure the rubber centering tabs are through the top cover or you might have a hard time screwing in the short screws. Reconnect the connector and reinstall the grommet onto the steel cover plate. I put some dielectric grease for peace of mind on the connector and relay. The relay was removed from underneath the dash on the drivers side (yellow).
Make sure to reconnect the hoses and clamps. I reinstalled the relay and she started right up. I then took her for a hard test drive around the neighborhood, getting her up to 60 mph. It ran like a scalded turtle on nitrous.
