What Is There To Do About This Problem
Posted in Ignition Systems | Asked on Aug 3, 2011
1992 Dodge Ram D150. 318 magnum.
I have a problem with my truck. I’ve narrowed it down to electrical. I’ve replaced the plugs, wires, ignition coil, pick up coil, cap, and rotor. My truck is getting fuel because it does start and run. Just poorly. I can get the gas pedal maybe a third of the way to the floor, and then it cuts out. Its kind of like it misses out, but worse. There’s nothing. It doesn’t shut off, but there’s no power or nothing. It sometmes pops and crackles if you hold your foot down long enough. I don’t think my timing can be messed up because I haven’t adjusted anything. It could be a bad sensor, but I don’t know which one it could be. I’m pretty sure my truck is too old to be put on a machine or have a code reader put on it. I don’t know what to do. I start college in six days and this truck is my transportation. Also, I don’t really have the money to be just spending it all on random parts that only MIGHT fix it. So please help me. Could my firing order be wrong with the plugs? Because I think my truck isn’t getting enough fuel or spark at high rpm. Could the order be messed up a little to make it run, but still screw it up at high rpm? Also, it seems to run worse when its warmed up. After having my foot in it for a little bit and it pops and crackles for awhile, I can smell the gas a lot. I don’t know if it’s too rich or lean. I don’t know how to tell the difference. So please help me.

Check the carburetor. If you smell gas that’s usually where the problem lies. Also check online for manuals for your vehicle. Chilton’s is a good repair manual and your local library might even have them in stock so you could look for free.
It could be your fuel filter, or a vacuum leak, it could also be your fuel pump, or just dirt in the lines or maybe an injector. There’s some injector cleaners you can buy that you just mix in with your fuel, read the instructions and warnings though. Also check for any hoses that are loose or have fallen off.
You should be able to have that looked at and given a better idea fairly cheap, some places will look at it for free.
OK, let’s back up a little. Did it run this way before you installed the new plugs and wires? If not, you have most certainly messed up the firing order when installing the new wires. If it was running bad before changing all those parts, you’ve got other issues.
And yes, your 1992 Dodge will store fault codes to be read by an on-board diagnostic tool.
The firing order on it is 1-8-4-3-6-5-7-2, id say you got the wires crossed up on it or disturbed the distributor wire that goes to it enough to cause it to loose connection on it,that will cause it to back fire and pop back like that,go back over it and also make sure that you gaped the plugs right in it,it just takes two crossed wires to totally make that engine fall on it its face like it doing,find no-1 on the cap an go clock wise with the firing order,i think you,ll find the problem with it,if your smelling gas fumes real strong its not burning whats getting to the engine and that may destroy the new plugs you installed in it,good luck with it.
Follow Dodge mans suggestions and I think you’ll find your problem. The unburned fuel you smell is what is not being combusted.
I believe you have two wires crossed, but follow his instructions. Two plugs firing out of order will give you the symptoms you have.
I think your truck has an OBD 1 connector, my ’92 Dakota is so equipped.
