Dodge Stratus Relay Guide (1995-2006): Solving No-Start Problems
A faulty relay is a common reason your Dodge Stratus won't start, but it's often a simple and inexpensive fix.
- A 'crank, no start' issue on a Stratus is very often caused by a bad fuel pump or ASD relay.
- Relays are located in the under-hood fuse box and can be swapped with identical relays for easy diagnosis.
- Replacing a relay is a simple, tool-free, plug-and-play job that any owner can do in minutes.
- For this part and vehicle age, an affordable aftermarket relay is a perfectly reliable and cost-effective solution.
Understanding Relay Failure in Your Stratus
If your 1995-2006 Dodge Stratus cranks but won't start, or stalls unexpectedly, a bad relay is a likely suspect. These small electrical components are found in the Power Distribution Center (the fuse box under the hood) and are critical for engine operation. The most common culprits are the Auto Shutdown (ASD) relay and the fuel pump relay. When the ASD relay fails, it cuts power to the ignition coils and fuel injectors, preventing the engine from running. A bad fuel pump relay will starve the engine of fuel, leading to the same result.
Symptoms of a Failing Dodge Stratus Relay
Watch for these common signs of a bad relay:
- Engine cranks but won't start: This is the most frequent symptom. The starter turns the engine over, but it never fires up because the fuel pump or ignition system isn't getting power. This often points to a failed ASD or fuel pump relay.
- Engine stalls after starting: The car might start and run for a few seconds before dying. This can happen if a relay's internal contacts are dirty or failing, causing an intermittent connection.
- No crank, no start: If you turn the key and nothing happens, the starter relay could be the problem. You might hear a single click but the starter motor won't engage.
- Fuel pump runs continuously: In some cases, a fuel pump relay can get stuck in the 'on' position, causing the fuel pump to keep running even when the ignition is off. This will drain your battery.
Quick Diagnostic Tip
Many relays in the Stratus's fuse box are identical. You can perform a quick test by swapping the suspect relay (like the fuel pump or ASD relay) with a known good one of the same type, such as the horn or wiper relay. If the car starts after the swap, you've found your bad relay.
OEM vs. Aftermarket Relays
For a vehicle like the 1995-2006 Dodge Stratus, a new aftermarket relay is a smart and economical choice. Relays are standardized components, and the technology is not complex. Aftermarket brands like Replacement offer a part that performs the same function as the original OEM part but at a much lower cost. Given the age of the vehicle, paying a premium for an OEM relay from the dealer provides little to no practical benefit for most owners.
| Part Type | Price Range |
|---|---|
| New Aftermarket Relay | $17 - $19 |
| New OEM Relay | $30 - $50+ |
| Shop Labor Cost | $49 - $72 |
Frequently Asked Questions
What is the ASD relay on a Dodge Stratus?
The Auto Shutdown (ASD) relay is specific to Chrysler-family vehicles. It's a master relay controlled by the engine computer (PCM) that supplies power to the ignition coils, fuel injectors, and parts of the fuel pump circuit. If it fails, your engine will not run.
Where is the relay box on a 1995-2006 Dodge Stratus?
The main relays are located in the Power Distribution Center (PDC). This is the black fuse and relay box found in the engine compartment, usually on the driver's side near the battery. The inside of the cover typically has a diagram showing which relay does what.
Can I replace a Dodge Stratus relay myself?
Yes, this is one of the easiest repairs you can do. It requires no tools. Simply locate the correct relay in the fuse box, pull the old one straight out, and plug the new one in firmly. It's a 5-minute job.
Are the fuel pump and starter relays the same?
Often, yes. Many of the relays in the fuse box are multi-purpose and interchangeable, as long as they have the same pin configuration and rating. Check the numbers on the side of the relays to confirm they match before swapping.
