Questionable performance

Has the check engine light ever come on? It sounds like you have a plugged catalytic converter. Here are a couple of guides so you can run some tests.

You hit it right on the money it was the cat that was plugged I got it replaced and now it runs like new. I love this site.

2000 Dodge Durango V8 Two Wheel Drive Automatic

Cannot get truck started, loses all power when I try to crank it. Have tested battery, starter, and alternator. I am at losss for what else it could be and am looking for suggestions. Could anyone help a non-mechanic compile a list of possible causes?

Pick your symptom:

Cranks but no start condition:

Fuel and Spark:
Get a helper disconnect a sparkplug wire or 2 and ground it to the engine at least 3/16 away from ground -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs,coil's resistances,distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it.


No crank at all/nothing/nada:

Could be the starter, starter relay, clutch switch/park and neutral switch and ignition switch assuming the battery and connections are good.

The gauge lights keep coming on and some heating from engine

Is the engine overheating?

I found out that the hose to radiator clamp needed replacing. The coolant was lo

That is good news and an easy fix. Let us know if you have questions in the future.

ok, ive replaced the battery and the alternator...i know both were in good condition cause i took the altenator off my dakota. problem is something is draining large ammounts of power. so bad to were the truck drains and dies after short driving distance...what is it?? i've been told a/c clutch or ground...need this running i got 3 kids...

Here is what I need you to do. You need to check for a draw. It sounds like you will find one. I will provide directions at the end of this post. What to do is this. You will be connecting a volt meter between the neg battery terminal and cable to see the draw. Remove one fuse at a time until the draw stops. That way we will know what circuit is attached to the draw.

Let me know what you find.

NOTE: YOU CAN READ ALL THAT IS THERE BUT THE LAST PARAGRAPH IS THE BIGGEST HELP IN YOUR CASE.

Joe

well i found it it was an a/c clutch drain...i unplugged it and now my volts are at 14 and running great but no a/c...

Have you tried replacing the clutch?

i also have an 01 dakota....its flashing a PCM code yet all the forums i've read said their trucks ran fine with that code flashing...mine LAGS really bad...i changed the plugs and plug wires that didnt do the trick. So i was thinking it was the CAT being glogged....whats your take on it?

What code is it? And yes, the converter will cause a power loss.

2002 Dodge Durango V8 Four Wheel Drive Automatic 185000 miles

I have a 2002 Dodge durango with 185,000 miles on it. Lately its been having really bad gas mileage, the engine will rev real high when i press on the gas pedal then a huge cloud of black smoke comes out the exhuast and the truck takes off. It has no real power now and slows really down going up hills. It also has a real strong smell of gas. I've pulled out the oil dip stick and checked the oil fill cap and both smell of oil and gas. I don't know what to check first.

Check the injectors and fuel pessure regulator if it's leaking.If not-inspect and test the following items below:

1.Defective Oxygen Sensors.
2.Coolant temperature sensor out of calibration.
3.Restricted air intake system.

its flashing P0601....which is a PCM fault....but others said it ran fine with that code flashing...thats why i figured the CAT was it.

How do I check the injectors and fuel pressure regulator for leaks?

Check the cat because it can cause a power loss as well as other things. Let me know what you find.

Joe

For the pressure regulator-pull the vacuum hose,if it has gas then it's leaking.

For the injectors-remove the fuel rail along with the injectors-turn the key on and see if it's leaking.

thanks joe...ill let you know im just ready for it to be over hehe

I unerstand. When they run, they're great. However, when there is a problem, they are a pain!

My wife was getting onto the interstate in her 2001 Dodge Durango 4x4. When she hit the gas, the engine would accelerate, but will not move. We tried putting it in 4 wheel drive, reverse, and nothing. it didnt make any unusual noises or give us any problems leading ..."

Automatic? if yes fluid good if manual clitch slipping?

Yes, It is an automatic. I just checked the oil and tranny fluid this weekend and the levels were good. I changed the tranny fluid about 10,000 miles back. It wasnt giving us any signs of any issues. Last Friday, we were driving in a snow storm and had it in 4 high, but we didnt go over 45 mph. No problems then.

Not much you can do yourself need to have pressures checked and electronics scanned in trans

Is there a sensor that could have failed to cause this?

Not that would take out all gears

I have a 01 Durango. I just replaced front drive shaft. Something still wrong. When slowing down or giving it gas to go its like the brakes are locking up or something. It has no power but tries to go. It will go after few minutes. Go to turn or slow down.

Would you repost info

Ok. thanks!

Let me know what repair shop says will advise on repair

your truck most likely overheated and it spit the coolant out of the radiator, try refilling the coolant and starting the engine, if it hits high temps again then mostlikely you have a thrermostat problem

1999 Dodge Durango V8 Four Wheel Drive Automatic

the engine will lose power at aceleration no mater what speed you are traveling even if you are driving at a set speed it will lose power

Lack of acceleration,chugging,hesitating,jerking,bogging,misfiring etc. could be caused by one of the following below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.

My 99 Dodge durango loses power when accelerating and now it won't start
