Hey,
I have a 1990 Grand voyager (3.3L) V6 that i can't get to start, I'm assuming its the fuel pump, but before i drop the tank down I wanted to see if anyone here may know if its something else. I don't use this van and it usually is just sitting in the drive way. About a month ago I tried to start it but I guess something had run the battery dead, when i tried to jump it the engine just cranked away. So I charged the battery for a few hours and it started but then died down immediately. So i stuck the battery from the other car in it and it started and ran fine. So i figured it was just the old battery wasn't charged long enough, so I charged the old one full and i know that it was full because it started the other car. When i put it in the van it started and stalled immediately a couple times and then just kept cranking away not even trying to start...weird...then i stuck the battery that made it run the last time in and it just kept cranking... I checked the plugs and they're giving a nice big spark. I pulled off the fuel rail and a little gas spilled out but then stopped, even when the engine was cranking no gas would come out. So from that i assume its the pump but maybe some sensor blew out and won't let the pump go?

I'd appreciate any help on this.

Thanks.

Dont know if it will help but here's a shot.

The manual says the wire to the fuel pump is dark green with a black stripe
if you can find it and give it juice some juice from a jumper wire you should be able to hear it. It is also fused at the fuse box or even under the hood.

If its not a fuse and it works when jumped check the emergency shut off switch (roll over switch. Good luck

If theye dont start right away they seem too flood real fast. Im tring to keep my carburated van going to stay away from the fancy ones

That is a nice van to have if it isn't rusted out.

Whack the bottom of the gas tank with a rubber mallet, if it starts, your fuel pump is bad. Not much else on that model to cause that problem you are having.

hey,
thanks for the replies guys. Yes it is a nice van, no rusted places and the interior is still in great shape :)
So I tried the tank hitting mallet technique and she started right up, I even stopped and restarted a few times, I'll have to go to a salvage dealer and get a new pump. The bad news is that while I was messing around with the fuel rail I must have broke one of the seals, so gas is leaking from rail joints. I guess I'll have to stick a new rail in too, the only way to get the old rail off is to remove the manifold. oh boy...
Thanks for the help,
Tom

Bernard,
Got to ask. What did whacking the gas tank do to fix his problem? Was there a float stuck?

Thanks,

The whack job will make fuel spurt into the fuel lines just enough to get to the fuel injectors, thus the car will fire. If you continue to whack the fuel tank, you can keep the engine running theoretically.

Thats a great trick to remember. Thanks!

The fuel pump in that model is still a mechanical device, mostly plastic.
They just wear out over time, average is from 70,000 to 135,000 miles.
Never let the gas tank run dry, that will destroy those pumps in a few seconds.
