Hi Pete, I'M Shaun

Hello Shaun. Nice to hear from you today! I'm sorry to hear you are having this problem. I know this can be frustrating.

Have you tried to clear the fault codes with the scan tool then cycle the ignition off for a few minutes and then back on to see if the codes return as well as see if the engine starts and runs then at all?

I have tried to clear the codes but the scan tool won't clear them, the codes clear when the EDC light stops flashing

I've disconnected the battery & left it for 30 mins but it has no affect on the EDC

Thank you for your reply and that information as this does help me better understand the situation.

Please give me one moment to type out some info for you. I’ll be right back!

Ok thanks

You are welcome. Thank you for holding Shaun!

The first code tells me that there is a fault with the engine speed sensor which is commonly caused by the crankshaft position sensor. When this sensor acts up or fails it will cause issues with the engine itself not being able to start. I suspect that this sensor is causing the no-start issue to where it has to be replaced. This sensor can cost around $200 to have replaced. The second code indicates an issue with the output speed sensor at the transmission/gearbox itself. This occurs when the sensor has an internal electrical fault needing to be replaced or when there is a wiring issue leading to the sensor itself.

Both of these codes need to be looked into and tested further and are best performed by a shop or dealer using their test equipment and diagrams/procedures to locate the issues. In most cases, it is the output speed sensor and the engine crankshaft sensor that has to be replaced to resolve both codes and the no start issue.
