Ignition switch replaced...now won't start

[particlewave]

Pull the start lock relay out, then insert a jumper wire between pins 30 and 87. Turn the key to start. If it cranks, the issue is likely with the DME/security lockout. If it still won't crank, the issue is likely the starter/power.

Thank you particlewave, where is the start lock relay out located? (driver's side trunk?) How do I identify it (#7)? If jumping those terminals does start the engine, can I shut it off by turning the ignition key off or do I have to remove the jumper? Is there any way to measure the voltage at the starter from underneath the engine? Looks like I need to remove many parts to access it from the top. I doubt it is the starter as I never had any problems starting it before...but electrically, anything can happen. Is there any way to directly test the DME/security lockout? Sorry for all the questions at once, but I think this is the right path. Thanks again!

I'm sure your issue is going to turn out to be something simple, though (probably related to the work you did).

I had a similar problem. Turned out to be the positive "ground" had corrosion. It is located in the engine compartment inside a small plastic rectangular box at the top of the engine near the fire wall. Pop open the box and check the connection for rust on a loose nut.

Thank you Turbodad. Battery was tested and fully charged up. Posts were clean.
