Obd1 code 87

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! Code 87 on your 1992 Chevrolet C2500 with the 454 engine typically indicates an issue with the fuel system, specifically related to the fuel pump relay or fuel pressure. Given that your truck is starting and then dying, it sounds like it may not be getting the proper fuel supply. Here are a few steps you can take to troubleshoot and potentially fix the problem: 1. **Check Fuel Pressure**: Use a fuel pressure gauge to see if the fuel pump is delivering the right pressure. For the 454, you should see around 7-9 psi with the key in the "on" position. 2. **Inspect Fuel Pump Relay**: The relay could be faulty. You can swap it with another relay of the same type (like for the horn or A/C) to see if that resolves the issue. 3. **Examine the Fuel Filter**: A clogged filter can restrict fuel flow. If it's dirty or hasn’t been replaced recently, consider changing it. 4. **Look for Wiring Issues**: Inspect the wiring and connectors related to the fuel pump for corrosion or damage. If these steps don’t help, you may need to consult with a professional mechanic to further diagnose the issue.
