If there is no spark or fuel, then the first thing I would do is check the vehicle’s fuses and relays, particularly the EFI main and ignition relays. It may be possible that one of these components has failed and is cutting off power to the vehicle’s ignition and fuel systems.

What do you do when your car has no spark?
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.
What sensors can cause no spark?
There are a few reasons for no spark, new coil pack could be defective, crank sensor, ignition module or bad wire in primary circuit, faulty ECM/PCM.
How can I fix no spark?
If you do not see a spark, there is an ignition problem. Remove a plug wire and insert an old spark plug or a spark plug tester into the end of the wire (the plug boot). Place the spark plug on a metal surface on the engine, or ground the spark plug tester to the engine. Then crank the engine to check for a spark.

What has fuel but no spark?
If there is no spark or fuel, then the first thing I would do is check the vehicle's fuses and relays, particularly the EFI main and ignition relays. It may be possible that one of these components has failed and is cutting off power to the vehicle's ignition and fuel systems.
Does the crankshaft position sensor control spark?
Without the crank position signal, the engine control module (ECM) can't detect where the cylinders are or how fast they're moving. If you have crankshaft sensor issues, the ECM can't synchronize fuel injection, spark ignition (for gasoline engines) or control variable valve timing.
What can cause a car to have no spark?
Loss of spark is caused by anything that prevents coil voltage from jumping the electrode gap at the end of the spark plug. This includes worn, fouled or damaged spark plugs, bad plug wires or a cracked distributor cap.
Car No Start No Spark No Injector Pulse Diagnosis And Engine Only Cranks Troubleshooting
What to check if there is no spark?
If the engine has no spark, check for voltage at the coil positive terminal when the ignition key is on. If there is voltage, the problem is on the trigger side of the coil (pickup, crank sensor, ignition module or primary wiring circuit).
What sensor would cause no spark?
A Bad Crankshaft Position Sensor ASs such, a bad crank position sensor often manifests as a failure to start, but more worryingly, it can cause the engine to stall at any speed. Begin by looking for a corroded, loose, broken wire from the powertrain control module.

Can ignition switch cause no spark?
No spark is one of the most common causes of a no-start condition. It's the first thing I check for. ... The igniter or ignition module, the pick up coil or crank sensor, the cam sensor, and the ignition switch are included.
Can you start an engine without a spark?
The engine should run without a spark plug or any ignition system, but must be capable of self ignition.
