Engine stalls

Hi joe, as I stated in the question, there is no check engine light. Truck runs great until this happens. Given the fact that there is no check engine light, it seems to me to not be a sensor or electronic issue, which leaves mechanical or fuel flow issues. The question if this is true is, is it the fuel pump or the gas in the tank, or the fuel filter which is on the fuel pump. Is there any way for me to determine what is causing this problem without replacing the $250.00 fuel pump?
Also as I stated in the original question, I changed the air filter and added octane boost and fuel treatment. That seemed to work for a month but now is not. Since then I have run the gas tank almost out of gas, the problems seem to get worse as I get lower on gas. I then filled it up and the problem returned with a full tank. The problem does not happen on my way to work, but happens on the way back in the afternoon. My work is downhill from my house. So this leads me to believe that something is in the fuel tank moving to clog the filter or it has something to do with the temperature being 50-60 degrees in the morning when I go to work and 75-85 degrees when coming home. What are your thoughts? The truck has 130,000 miles on it. Thank you for your help.

Hi:
At this point, I would suggest that the fuel pump be checked for both pressure and volume. Based on your description of the problem, the pump sounds bad to me.

It is common for the pump to cause the symptoms you have described. Especially the fact that you have the trouble on your way home (up hill) when the greatest load is placed on it.

If you have never checked fuel pump pressure / volume, I would suggest having a mechanic do it for you.

If you have any further questions, let me know, and I'll do my best to help you.

Hi:
is the truck running again? Did the check engine light come on? You may want to have the computer scanned for trouble codes. Most nationally recognized parts stores will do it for free. My guess is there is a problem with the knock sensor.

Let me know what you find.

I have a 1998 Dodge Dakota 3.9 v6 automatic and am experiencing intermittent cut-off (dies). No obvious clues (hot/cold/wet/dry/load/noload/etc) it will run fine for days then die 3 times in an afternoon. There are no codes that are set in the computer. I replaced the crankshaft position sensor with no-joy. I'm not sure if it's losing fuel or spark, but I suspect spark.

Hi

First, when it cuts off, does it start right back up? Also, if not, that is when you need to check for spark and fuel. You may want to check fuel pump pressure to eliminate the pump. Regardless, one will be missing (SPARK / FUEL) and then we can try to determine where the problem is located.

Let me know.

The truck shut off 3 times today two were at a complete stop with a cold engine and one was backing up after a 10 mile ride. I have received the following error code only on the first shut off. P0300 random misfire on cylinder 3 and 5. The truck was not sputtering or knocking it just shut off. I cleared the error codes and did not receive any more. Each time the truck starts right up with out any issue.

Thank you

Check the crank sensor to make sure the connector is tight and clean. Also, when it dies, do you feel a miss first?

Sounds like its starving for fuel. Replace the fuel filter. Its the most overlooked, and the cheapest. Let us know the results.

Hello

The code means intermittent loss of CMP (camshaft position) or CKP (crankshaft position).

I could attach the troubleshooting charts but you do need a scan tool to do the checks for the crankshaft sensor. Let me know - they would be small but we can try.

I have attached a chart showing the two sensors for the code.

It will be a little hard to see, but the square to the left is the PCM. The top circle is the CKP and the bottom is the CMP.

My thought is one or both sensors are going bad.

Hi, my problem is that my truck will randomly stall out during all types of driving conditions. Whether the climate is hot or cold or if the engine is hot or cold. If I drive fast, slow or sitting idle it will do the same. I have replaced the fuel pump, O2 sensors, Throttle Position sensor, Air Idle Control, cleaned the carburetor and done a complete tune-up. Please help!

Hi:
Will the engine die at highway speed while you're on the gas? Also, when it dies, how long does it take until it will restart? Finally is the check engine light coming on? It sounds like it could be a map sensor, but I can't tell you for sure without a code.

At highway speeds, it hesitates briefly but keeps going since the gas pedal is down. When it dies, it will start back up immediately. And finally, part of the problem is that the check engine light has never come on while doing this. Thanks for your impute on the MAP sensor, I will try that. I appreciate any help so much.
