Where it lives

For P2A87, the circuit described runs through the pump. The description of P2A87 reports the pump as open.

Check these first

• An open in the alternative fuel pump C compression stroke valve control circuit
• A failed pump C compression stroke valve solenoid
• A corroded or backed out pin at the pump C compression stroke valve connector
• A broken wire in the pump C compression stroke valve harness
• A control module that cannot drive the pump C compression stroke valve

What to do next

1. Command the alternative fuel pump C compression stroke valve with a scan tool
2. Test the pump C compression stroke valve control circuit for an open
3. Check the pump C compression stroke valve connector pins
4. Measure the pump C compression stroke valve coil resistance
5. Replace the pump C compression stroke valve if the circuit tests good
