94 doge caravan about to get the sledge hammer.- fuel promblem
Question -
i have a 94 caravan 3.3L two wheel drive. im rackin my brain here over
this fuel pump promblem i am haveing. my wife go"s to leave and the van
wont start. i spray it with either and it will start and then dye. so i
narrowed it down to no fuel. i could not hear the pump turn on. so i
pulled the pump and bench tested it and it seem to be workin just fine.
so i went back to van and started to check power going back to the pump.
with the pump out and a test light hooked to the power lead, it seems i
was only getting hit & miss power threw the plug. then i notice the
clicking of the relays. on normal start you should hear 2 clicks from the
relay box{auto trans-fuel pump relay}. when turning the key on and off,
i would only get the 2 clicks and the test light to light up about 5
times out of 20. i tryed changeing relays around, tryed a different relay
from another van and still had the same result. seems the fuel pump
relay does not click half the time when turning the key on. this is with
the tank dropped, pump out, and all pressure released at shrader valve.
i disconected the battery for about 7 min, recontected, then it seemed like
everything started to work fine, so i plugged the pump in and it all seemed
good. i put it all back together and the van fired up and i drove it for
a about a week with no prombloms. but now it wont start again with all
the same prombloms. the relay is clicking hit-miss again. at the
begining i thought right away i would just have to do a fuel pump and be
done with it. autozone said you have to buy the whole sending unit and
they want $150. with this electrical promblom i think im haveing, i dont
want to drop $150 in the tank and that not be the promblom. its been 3
days now and it still wont start. the fuel pump wont come on. so i am
going to run direct power and see if it works. .may be im just over
thinkin things here with the price of that pump and all, but something just
dont feel right. . please help. this is our only car we have to haul
the baby seats in...thanks...perry
heres a follow up on my caravan fuel promblom above. -- i pulled the fuel pump
relay out and ran a jumper wire to the terminals and the fuel pump came
on. so i put it all back together, and now the stupid thing is sitting in the driveway starting and running fine. but i still cant let my wife drive it because i did not fix a thing. i did all this last week and it ran for about 4-5 days, then left her straded.

The problem sounds like it's between the switch and the relays.Check the switch.It could also be a fault in the wiring,you might have some success with running new wires to the relays.Use a circuit thats only hot when the ignition switch is "on".OH CRAP that's where the problem started anyway!!!

perry – I am having the exact problem with my ’94 Dodge Caravan. Can you please post if you fixed your van and how. I need to fix mine soon since it is the main transportation to haul my baby seat.
Thanks.
Thanks.
