I recently purchased a 2006 Dodge Ram 1500 SLT with the 5.7L Hemi engine. I have only owned the vehicle for a week and today it would not start after running perfectly for the last week. The starter does spin the engine fine, but it just doesn't fire. The truck has about 64,000 miles on it.
We all know the engine needs three things (fuel, air, and fire) to run. I believe I am not getting any fuel to the engine. The air filter looks brand new, and when I used just a little starting fluid, it fired right up and died immediately (I know fuel starter is bad juju, so no sermons please.) The brain is not throwing any error codes at all.
By process of elimination, that leaves the engine getting no fuel. (I think) Does anybody have any ideas. I believe I checked all the fuses in the power control module under the hood.
Also, I hate to introduce any new variables into the equation, but for imformational purposes:
I installed my aftermarket Kenwood CD-player using the correct wiring harness and power module (to supply accessory power) that I had originally had in my Dodge Magnum. I tapped into the cigarette lighter for the accessory power.
I installed my Tekonsha Prodigy brake controller using the 3020P harness plugging directly into the brake controller socket under the dash.
I filled the gas tank a few days ago with 87-octane fuel.
It has been hot down here in Florida, and it rained all day prior to my truck having the starter issue.
After installing the brake controller and stereo, the truck ran fine, so I don't think I screwed anything up. Also, I made sure to disconnect the negative battery cable from the battery as I was installing these accessories.
Thank you very much for any help you can offer.

It ran for a couple seconds (basically long enough to burn off the starter fluid). I will check and see if I can hear the fuel pump tomorrow. How can I tell if I'm getting fuel at the rail? Is there some sort of fitting I can disconnect to see fuel flowing? Thanks for the help so far.
grab a fuel pressure gauge or just hit the little pin on the fuel line (there's a little plastic cap you unscrew). If you have fuel pressure, you'll know it.

I don't have a Hemi, but it won't start just the same. Don't know this fuel rail or pin? I am Deaf, can't hear the pump. But it looks like it is definitely not getting fuel to carb. Where is the fuel pump?
The fuel pump is in the gas tank. After turning the the key on engine off, your pump should prime and pressurize the fuel rails. There's a schrader valve on the fuel rail (I think on the passenger side) you can tap real quick to see if there's pressure, be careful if you check it that way since it could be under pressure if the pump is working. It's better to actually hook a gauge up, but it's a quick check if you don't have one on hand.
