I changed the fuel pump and the crankshaft sensor; I still have no spark. What else can I check?

Hi Jennifer,

Do you have spark to any of the plugs? Have you checked for diagnostic trouble codes?

Here is where I'm going to start. If you haven't already, scan the computer to see if there are stored diagnostic codes. Here is a quick video showing how it's done:

If you have already done that or there are no codes, next go to the ignition coils. Locate the black wire with a white tracer on each of the coils. I need you to check that wire on each coil for continuity to ground. Here is a link you may find helpful:

If you don't, locate the same color wire at the lower right hand of the dash. That is the ground location. Confirm the wire is in good condition, not corroded, and not loose.

Next, you will need a helper for this. Each of the coils has a red wire. Ignore that wire. There is a third wire, and it will be a different color at each coil. Should be pin 1 in the connector. Have someone crank the vehicle while you check for power to that wire. It will be a pulse signal and not constant power.

I attached the wiring schematic for the coils and ground below for your reference. Try what I mentioned and let me know the results.

Take care,

Joe
