I need to ask a technical question as to a engine light and rough idle after running out of gas.
Can someone direct me.
Thanks

 

Start out with a bottle of HEET water remover in your gas tank. You may have stirred up the crud in the bottom of the tank.

 

I'm planning on doing just that.
I'm thinking that the engine light has to do with the throtle sensor. I was trying to give more gas when it finally died.
Just seems weird that I got a engine light after running out of gas.
Any thoughts on this?

 

Have you pulled the engine code yet? If not, go by AutoZone and have them read the code and we'll able to better help you. At this point it would just be a guess.

 

No auto zones in area. I'll see if O'Reilly's can do it for me.
Thought I once read somewhere that you can pull the codes from turning ignition on and off a few times. tried three off/on times and nothing.
Thanks

 

The key trick does not work on a 98 for some unknown reason. And use Techron plus. You will also want to buy an inexpensive fuel pressure tester and check pressure(49lbs give or take a couple lbs) . This would not be the first time I saw a pump go bad after running out of gas.

 

Who would have thought that the "E" on the gauge does not mean "Enough?"

 

Actually, The fuel pump and sensor was just replaced. It appers that 1/4 tank is now EMPTY.

Engine codes are P0300 -P0301- P0305 all pertaining to misfiring in cyclinder 1 and cyclinder 5. I put a bottle of injector cleaner in and now I guess it's a wait and see game. I haven't investigated the idea of pulling the injectors themselves and cleaning them. I also learned that this Dodge does not have a fuel filter but only a screen on the pump. You would think that for something as critcal as having clean injectors that there would be a fuel filter that is easily replaceable.
Anyhow, the engine still runs rough. I'll look into cleaning the injectors or perhaps replacing 1 and 5.

 

You're getting a random misfire followed by a misfire on #1 and #5. A bottle of cleaner isn't going to correct those codes. More than likely, there's an issue with the plug wires (eg, mis-routed, melted covering and making contact with engine metal and grounding). It could also be a problem inside the distributor, such as burnt contacts or the CKP sensor could be dirty or even cracked. Don't just throw parts at it in hopes of fixing the issue. Examine each item carefully, clean all connectors, etc.

That is partially true. There is a screen at the pickup (suction inlet) followed by an inline filter cartridge inside the pump, and finally the pressure regulator, mounted on top of the fuel pump body, acts like a third stage filter. So, in actuality, this fuel pump does a more thorough job than most other setups.

 

Good advise,
I sort of thought myself that an ignition misfire could only be related to the ignition system and thought "how could a dirty injector cuase a misfire"? I too beleive that there might be something else happening. Just seams odd that this occured after running out of gas. Maybe some more history of the truck needs to be explained.
The truck lived in sunny Florida until now. It just completed a 1744 mile trip from there to northern Wisconsin. We went from 75 dgree temps to now 15 degree temps. And like I said earlier, It ran perfect until the gas issue. The engine light was reset and has not yet come back on even with the engine still running rough. The mechanic said it might come back on but should clear once the injectors clean.
I'll take a look at the ignition system today to see if I can discover anything.
Thanks for the reply
