    Wont start

    I have a 1998 TA I just completed a 6.0 swap. It will turn over and will fire if you give it a sniff of starting fluid. The fuel pump is running I checked the fuse's and the ENG SEN fuse under the hood was blown and keeps blowing. But with it blown the starting fluid will help it fire just for a cupple seconds. Can the ENG SEN have anything to do with it ? Any help would be great.

    it sounds like its not getting fuel what its running on is just the starter fluid , then once it is all burned it obviously stalls out

    Are the fuel injectors flowing?

    I had this exact issue when I swapped an engine into my Ranger pickup.

    Turned out the fuel in the injectors had turned to varnish.

    Replaced the injectors and all is ducky.

    As far as checking if the injectors are firing, there is a test light that plugs in in place of the injector. It blinks when the computer is trying to fire the injector. That's how I found my problem. A friend used to be a mechanic at a dealer and he loaned me his test light.

    Good Luck!

    Don't think you should ignore problem #1( ENG SEN fuse blows) and move on to #2,engine won't start until #1 is solved
    Service manual says ENG SEN fuse has to do with O2s,MT6,MAF sensor!!!,and stop lamp switch
    Maybe something with the way the MAF is connected? I'm thinking you need fuel AND air for ignition so maybe MAF problem?
    Good Luck ,keep us posted.

    IT'S ALIVE my dumb ass forgot to plug in the crank sen. It's behind the starter. It fired right up. As far as the fuse I had pinched a o2 wire I moved it and fixed that problem .

    When your doing a project like this all you have to do is take your time. And time is somthing I dont have. I got in a rush and look what happend I end up spending more time in the end. Thanks so much for the help. Chad 1998 WS6 ram air 6speed vert.

    i have a question. dont kill me because i know this is a simple one but if the O2 sensor can make the car run bad and use more fuel, then what actually happens when you eliminate them when running an ORY.

    You have 4 O2's on the car, an ORY does away with the 2 rear sensors ( post cat). Those just keep tabs on the cats. The front 2 are the O2's that control fueling.
