Ok, I just had a quick question. For those who remember me; I'm the one that posted a video of my Silver 2000 Dodge Neon on youtube and asked for help as to why it would crank. It tried to turn over but it just wouldn't start. I also stated that my dad said It's something wrong with the wires. He said the car doesnt get the signal to ignite wich starts the car.

So I was doing my research and thinking what could be the problem. My car started before but the idle was horrible. It kept putting. I don't know if it was because of the old [5 year old] gas. Since then my dad has pumped the old gas out and put new gas in. We also installed a different ECM because the old one went out after it was idling for about 20 seconds.

Now this is when I posted the video. It's trying to turn over but wont. Is it because of the different ECM/PCM? If so, wich I think it is, does it mean Im going to have to find someone to reprogram it and how much does it cost?

1). DEFINITELY get some fresh gasoline in there. 5-year old gas can gum up injectors, valves, piston rings, etc.

2). Do you have the "Sentry" or SKIM system activated on your car ?
If so, you will need to have the "new" PCM programmed with the VIN for it to start.

If your Neon has a gray ignition key, you have the SKIM system, and you'll need to have the VIN programmed by the dealer.

I think I have the "Sentry" system. My Dodge Neon has a black ignition key.

Nope. Black means no chip to program.

Grey keys have the chip though.

Did you purchase this replacement PCM new, or used ??

Also, do you hear the fuel pump 'hum' when the key is turned 'on' (before actually cranking ??)

The purchased PCM is used. (I think thats the problem because it isn't programmed to my car)

When I turn the key on I do hear a 'hum' for a split second.

Actually, that looks like a Sentry Key--it's fat and oval.

Mat.... That can't be right...... :scratch:

I have the same (black) key for my 2000 Neon, it's a base, stripped-down model, and does not have Sentry.....
I was able to replace the PCM in my 2000, without having the VIN programmed in.

My understanding is that the Gray keys (only) have the Sentry chip......
Someone please correct me if I am wrong.

No, Nick you may be right. I could *swear* my wife's old '00 with Sentry had a Chrysler emblem on it like that one. My '02 with Sentry key has "Neon" on it. And the more I look at it, that one does look black, not charcoal like I thought.

I thought the PL2 base Neons used the old-style trapeziodal keys....no?

Even if there is a skim related issue with the car it should still run for 2 seconds then die, a red light should also flash on the cluster when this happens.

^^ That's only supposed to happen 3 times. Then you get nothing.

Yup did this on a friends SRT after the Stage 3 install. Dodge sent the PCM with the wrong VIN in it. New flash and it fired right up.

You may need your vin flashed into the ecu. But, for leaf spring juice and giggles, unhook your cam position sensor and crank it for a few seconds and see if it does anything good.

Everything is working fine. The only problem is that its not firing. I have new spark plugs, a programmed ECU, new fuel and new fuel pump. For some reason its not getting the signal to fire. Does anyone know how to fix this problem?

Try unplugging the cam sensor. It wont throw a code for it, but it wont start. I had the same problem when I swapped my head, and it wouldn't spark. If not that, then also try changing the crank position sensor. They go bad with no warning.

That means it is getting spark. You wouldn't get a back fire without any spark, especially on a cold engine.
Are the plug wires in the correct location?

My car would do the same thing with the cam sensor hooked up. Crank crank crank crank, pop, crank crank, etc etc.

How did you fix it? My car is running now. When the cam shaft sensor is hooked up it doesn't want to start. But when the sensor is disconnected it cranks and runs fine.

You are trying to link to a site like photobucket, right?

you need the image url. if the image in already on the computer just right click on the pic and go to properties. from there a box should pop up with the image's URL or ADDRESS. copy that address and place it inside "[img] [img] ".


So your post should be [img](address or URL here without parenthases)[img]
