No Crank

[Beau75]

Hey, I have a 2005 gt manual that has a no crank issue. The car has power and a good battery and I confirmed that the clutch pedal switch is engaging. What other things should I check for.

I'd start the chat by checking the starter relay. Pull another relay and swap it out, and see if it cranks. How many miles are on the car?

Just listed basic troubleshooting steps. See: https://www.s197forum.com/threads/no-crank-no-start.154644/

Good luck

i dunno if that just cuts fuel or a no crank condition ?

The kill switch you're referring to is the fuel pump inertia switch that's activated in the event of a crash in order to cut off the fuel and prevent a fire. The engine would still crank but not fire up.
A no crank situation with power and a good battery suggests there might be a faulty clutch pedal safety switch. Even if the button on the switch appears to go down normally, there could be an internal fault that's preventing 12v from going to the starter. I suggest you unplug it, jump the two terminals of the wiring harness with a paperclip, and see if the engine cranks/fires up.

You need air, fuel and ignition for an engine to run.

Check the usually suspects, applicable relays, is fuel pump priming, fuel at injector rail, inertia switch reset, clutch/neutral safety switch, spark from plug wires, no obstructions in the intake track, battery and cables, etc.

Old school methods…. Turn the steering wheel full lock and try starting (ignition switch might be going bad). If the starter is seized a lite tap with a hammer might dislodge it… push start it and see if it runs, etc.

I have to ask, any codes and how was it running prior?

Forscan or a decent diagnostic tool will tell you if the clutch switch is opening and closing and if there any codes stored to point you in the right direction.
