Check for applicable mil codes. You can check those codes, yourself. Have a helper crank it, while you visually check for spark at the plugs, if you have spark everywhere, use a gage and check fuel pressure.

Are you saying at the moment, the starter won't crank? Check that the battery has a full charge, all battery connections are good. Check your security system, where applicable.

Kindly turn off the capital lock and put some punctuation in there so it makes sense. This can be read three different ways and is very confusing.

Any Applicable mil codes? You can check mil codes, yourself. You turn key just till the dash lites come on, no further, no crank. Cycle the key on--off, on--off, on, then the mil starts flashing, you count the flashes to get the codes. Your looking for two digit codes.

Did you check for primary voltage at the coil, engine cranking, dark green wire with orange tracer should be hot/voltage.

The asd relay supplies voltage to several circuits, the coil is one. Usually, if the computer doesn't see the proper cam and or crank sensor it won't ground that relay. Any electrical part, if there is a problem on the wiring circuit, replacing the part won't fix it.

You should have got some type of code even if all clear. You might have to check voltage and grounds at computer?
