Hello, i have the SUV listed above and it will not start it just cranks and will not start. What I have done is; changed the ignition, coil spark plugs, and wires and still nothing. I'm sure that it is not getting any spark from the plugs or wire. I also changed the rotor. I can't think of any thing else to try. I also know that the fuel pump is running and it is getting gas. please help me figure this out.

Good afternoon.

When you crank the engine, does the tach move up a little showing RPM? that will tell me if the crank sensor is working. If it does not, there will be no spark.

I would also check the fuel pressure. The pump can run but not produce pressure.
