so from the codes do you guys think it could be my fuel pump?? and where should i look for a big leak?

well like i said before you need to have it smoke tested.. OR you can give spraying carb cleaner all around your engine bay a whirl. if the rpms rise then your vac leak is in the area where you sprayed the carb cleaner.

gaskets go bad and leaks happen. have you even attempted to look for a vac leak yet?

as for the fuel pump circuit codes. check your relay to see if it clicks (feel or listen) when you turn the key forward. it is located under the drivers seat (in foxes not entirely sure about sn) also can you hear the fuel pump prime when the key is turned forward? whats your fuel pressure? does it retain the same pressure after turning the key off or does it fade down?

and didnt you say you only replaced one O2 sensor? why not both?

and i believe if you do have an intake leak your engine will run lean because of the extra un-metered air that it is recieving. thus upping your afr

Please do not try a shocking experience. Easier to run cylinder balance test. Do run test at end when flases last of codes goose the throttle. Will start cutting fuel one injector at a time(will feel the miss) and continues untill gives a code9=pass 1-8the cylinder that is a problem do this 2 more times(goose throttle). 50%,25%,15% Get a 9 code is telling you all cylinders are within 15% of each other, no problem. No doubt pulling plug wires off is much quicker. Had a eaking plug wire on car at shop and put my hand to close. Fire came out what was close to ground. The fender via my pants zipper. Another mechanic and service manager witnessed it. They found this to be the most amusing thing in the 10 years I was there. I on the other hand had to take some needlenose pliers to restroom to take a leak.

On the sn cars the fuel curcuit runs thru a multifunction box that hangs over the radiator in front of the altenator and there you will get your clicking of the relay. fyi!

When you switch the key on to prime the fuel system if it dosent make a distinctive running sound the pump maybe on its last limb! (in the theoretic relm of redneck tech)

no more solo advise i`ll just ride the wagon!

i hear it prime from time to time

well if thats the case and it isnt noticable everytime u may need a pump! you can have good pressure at idle but lower at load!
