20 Most Recent 1997 Dodge Ram Questions & Answers

On a 1997 Dodge Ram Van, the relays that are located on the firewall are likely to include:

• Fuel pump relay
• Headlight relay
• Horn relay
• AC compressor relay
• Engine control relay
• Automatic shut down relay (ASD)

These relays are responsible for controlling various electrical components on the van, such as the fuel pump, headlight, horn, and AC compressor. The specific location of these relays on the firewall may vary depending on the model and trim of the van. If you are having an issue with one of the relays on the firewall of your 1997 Dodge Ram Van, it is recommended to consult the service manual or a mechanic to determine which relay is causing the problem and how to fix it.

it's none of the above. dodge doesn't like to do a good job on the ground system. if you beef up the ground system most particularly from the back of the motor to the frame and be sure your making great contact from the battery to the engine and from the engine to the frame your PCM wont go out on you. bad ground creates resistance and will cause the pcm to go out. it's not your fuel pump, pickup coil tank case sensor or iac. tell tale sign of this condition is you have to do a key dance to get it started ( no it's not your ignition) stalls when running down the highway and or will run rough and possibly backfire after it was just idling fine. The PCM is babbling to the engine. Sometimes the iac will cause it to run rough if the end is dirty but what I explained is the usual issue. PCM 300 dollars. I did not return old one for core $70 because a dealership can reprogram the pcm if it's not burned out because of the poor grounding system. Thanks Dodge. ??

Dear Mike, Your truck is a prime candidate for this problem. Here are the things to check. Start with the battery, have it "load tested". That is where someone drains it with a short for about 3-5 minutes, to take the "surface charge" off of it. If it is good after that, clean the battery posts shiny bright, then go to the cable terminals. Clean them shiny bright INSIDE. Examine the battery cables. Corrosion can build up inside the plastic covers and spoil the cables invisible to the eye. Next take the starter and solenoid apart and look for fried contacts, or worn brushes. God bless your efforts.

Check if equipped for anti theft system. Usually the anti theft will allow for initial spark and then kill the fuel injectors! Disconnect the battery and have it recharged and tested, if it fails the test replace it. Use the key and manually lock and unlock the drivers door if the alarm is still set, There is a switch attached to the door lock that disables the anti theft. If the driver's side is defective switch you have to do this from the passenger door. Hope this helps?

Reverse band is not operating correctly most likely. You need to take it to the tranny shop. If you drop your transmission pan and took very detailed pictures, I might be able to confirm your problem.

Find the tail light fuses. They should be under the hood near the battery by the firewall. If not there look under the dash to the left of the driver. If it's not a fuse, then it's probably a broken hot or ground wire in the wiring to the trailer. Hope this helps.

clean throtle plate

may fit if same size no problem but need to take sensors etc from original also has to have same upper intake most likely

What sensor .

I would say you are right in your guess about a vac leak. You should be able to trace the hoses from the engine to the dash to find it.

check to see if vacum line has a hole or has came loose from vacum gas ball.

No idea as never see these motors here in spain but look in the power distribution box under the bonnet and check their first ,some vehicles have a fuse assembly within the lid of the battery box like VWs and seats also some renaults as i remember

Clogged Exhaust Converter ? Or 5 other things !!

run fault codes and look for a canister purge valve problem as I suspect that what you have is a fuel tank not venting properly and causing a vacuum in the tank which is preventing fuel being pumped through the system ( same affect as blocked filters)
