I have a 1997 3.3L Dodge Caravan. Fuel is leaking out tailpipe and smoking bad. The oil is not milky. Changed plugs, made no difference. Check Engine Light is on but can't get it any place to get codes. Does anyone have any ideas what the problem is?

Are you losing coolant and what did the old plugs look like?

Getting the codes could really help narrow things down since they may tell you what cylinder or cylinders are misfiring. If that much fuel is making it that far, one or more of your injectors must be spraying in too much-- could be a stuck injector or one or more injector control wires shorted to ground causing them to remain open.
If you pull your plugs that could help-- look for plugs that are wet and that would be the place to focus your attention. Make sure you keep track of which plug comes from which cylinder.

The problem was a stuck injector. Got 6 injectors from boneyard, replaced front 3 and solved the problem. Service Engine Light even reset itself. Thanks for the help

the injectors are in the valley where they are quite accesible
the rear plugs - now there is another story

tell me about it. i just changed my plugs on the '98 GC SE and they were a pain. i thought i would never finish it. all skinned up from the back three. the old reach-a-round. no room for any thing back there. i got to get ahold of the special tools then it'd probably be fun to work on them. i know they have to have something.

A Dodge mechanic told my husband to pull the wiper cowel off to get to the rear plugs. He said that's how they usually get them with ease. Haven't tried yet so we don't know if it really works or not. We did have to replace the seals around one of the rear injectors because it started leaking fuel.

Yes, it's a lot easier that way. The prospect of doing it seems to intimidate some people though, but it's not that hard.

i did take it off. yeah, it did make it easier, for the first timer though it was still tough. it'll be no problem next time.

Haven't done the rear plugs yet but can reach 2 of 'em from the front.. by feel.
Pretty sure the intake (upper maybe..) manifold has to come off on my 3.3, to get to the rear injectors.
Don't see any other way to deal with the rear fuel rail. Front injectors are no sweat.
The fuel rail on mine is one piece, u shaped & loops from the front back into the valley.

91,
I just replaced the head gasket on my 93 with a similar fuel rail. I would suggest pulling the air plenum and working with the back three then. While you're at it, change the back plugs also. That is the only way I know of to make it easier. Be sure to note the vacuum line positions and check their condition while your at it. I found a cracked line within the protective cover. Once I got it back together, has been running like a champ, like a DODGE should!
