If your 1990 Volvo GLE 740 won't start and is missing a knock sensor, it could lead to ignition timing issues, but the absence of a knock sensor alone typically wouldn't prevent the engine from starting. Check for other common issues, such as fuel delivery problems, ignition system failures, or electrical issues like a dead battery or faulty starter. Additionally, inspect the fuses and relays related to the fuel and ignition systems. If everything else checks out, consider having the engine's diagnostic codes read for more specific insights.

1990 Volvo 740 GLE will the knock sensor cause the car not to start?
Yes, a faulty knock sensor in a 1990 Volvo 740 GLE can potentially prevent the car from starting, though it is not the most common cause. The knock sensor's primary role is to detect engine knocking and adjust ignition timing accordingly. If the engine control unit (ECU) receives incorrect signals from a malfunctioning knock sensor, it could lead to improper fuel-air mixture or timing issues, which might result in starting problems. However, it's essential to check other components as well, as there are many potential reasons for a no-start condition.

The knock sensor on a Chevy Celebrity 2.8 L engine from 1987 thru 1990 is located on the back side of the engine(next to the firewall) below the exhaust manifold. There are actually two sensors there, one is the knock sensor, the other is the crankshaft position sensor.
