Yes, a bad ICP (Injection Control Pressure) sensor can cause an engine to not start. The ICP tells the engine computer how much fuel is being delivered and when it fails or reads incorrectly, the fuel mixture will be incorrect resulting in a no start. In addition to this, other issues that can arise from a faulty ICP are: loss of power during acceleration, rough idling, stalling and poor performance. Therefore it’s important to test your vehicle’s ICP if you experience any of these symptoms as finding and replacing the faulty components in your engine will help ensure that it starts correctly every time!
