Indmar fuel pump troubleshooting

If you are having issues with your Indmar fuel pump, there are several troubleshooting steps you can take to try and resolve the problem.

Firstly, check your fuel levels and gauge. Running your vehicle with low fuel levels can cause issues with your fuel pump and fuel delivery. If your fuel gauge reads empty, fill up your tank and try starting your engine again. If the engine still won't start, you may have a fuel delivery problem. Try dribbling some gas directly into the throttle body (TB); if the engine starts briefly, then you are likely dealing with a fuel delivery issue.

If you suspect a fuel delivery issue, you can try clearing the air out of the fuel line. To do this, locate the Schrader valve on the pressure side of the fuel line and press it with some rags. Then, cycle the key off and on a few times to release the air. If you continue this process and still don't get fuel, you may need to replace the fuel filter. A clogged fuel filter can prevent fuel from reaching the engine, causing the engine to stall.

Another potential issue is vapor lock, which tends to occur on hot days and can cause stalling or difficulty starting the engine. Vapor lock can be prevented by using a fuel pump vapor lock prevention kit, which keeps the high-pressure pump primed with fuel. Additionally, it is recommended to observe the manufacturer's maintenance schedule and change fuel filters on time to avoid problems.

If your fuel pump is running continuously, even when the engine is not spinning, this may indicate an issue with the oil pressure switch or the crank position sensor. The oil pressure switch may be malfunctioning if it constantly senses oil pressure, causing the fuel pump to run continuously. On the other hand, if the crank position sensor is not sending the correct signals to the ECM, this can also affect fuel pump operation.

In some cases, the issue may lie with the wiring harness to the fuel pump. If the wiring harness gets hot, it can cause the fuel pump to malfunction. Replacing the wiring harness may resolve this issue.

Finally, if you have a fuel-injected engine, ensure that the injectors are not firing when they are not supposed to be. If they are, this may indicate an ECM issue.

If you have tried these troubleshooting steps and are still experiencing issues with your Indmar fuel pump, it may be best to consult a certified mechanic or seek advice from an Indmar forum.
