Last week, I bought a replacement battery and a new cable for my Dodge D300. It was working fine not until this morning, when I badly needed my truck. I turned the key, and it kept on cranking without firing. I removed the battery, and tried again. It worked fine for a short while, and then it died on me. Did I just purchase a junk battery, or is there something wrong with my vehicle?
It could probably be due to a junk battery, but there could also be other reasons why your truck doesn't start even with a newly replaced battery. You might need to check if there is corrosion on the contacts inside the relay and the switch. Inspect if the ignition points of your truck are also corroded. Replace them with new parts, and try to turn on your truck again. If it still won't start, try wiggling the firewall connector, and see if it makes a difference. You may consider replacing the cap and rotor, and make sure to buy the one with brass inside it. Make sure the coils are connected properly, and are rust-free.
I think my Dodge D300 is having a fuel problem. It cut out on me while I was driving it yesterday, and I noticed that the fuel filter was not working properly. It was not being filled with fuel like it should. I thought that the gas cap might be worn out, but it is in good condition. I checked the stock pump, and it is not that worn out yet. What could be wrong?
It is important that your fuel filter is always in good condition. This is the component that cleans the fuel and helps protect fuel injectors. If it is not doing its role correctly, it can cause the fuel injectors to be clogged. When this part is being faulty, it can cause the Check Engine light to turn on. It can also cause engine cylinder misfires. If you have time, you can consider dissecting the fuel filter to know what's wrong with it. You can examine the contaminants trapped inside. It can also help you decide if you need to replace the fuel that you are currently using. Dirty fuel is one of the culprits for a bad fuel filter. Replace it regularly to remove contaminants and reduce restriction to fuel flow. Using fresh filter can contribute in extending the lifespan of your fuel system.
When my ignition switch is in the "start" position, I still don't get the standard 12 volts at the primary. It runs fine in the ignition switch "run" position though. I've checked the wiring diagrams for my vehicle, but it's different from what I have. What should I look for?
You might be looking at the wrong manual because the wiring diagrams should be the same. Perhaps your vehicle is among the trucks that were found to have an underpowered engine, which causes the problem in the ignition switch. The start circuits of those trucks were also rewired.
