No crank, no start after changing Flex plate and starter

The click that you are hearing is the starter solenoid pushing the pinion (teeth) out and it is banging into the flywheel teeth and they are not messing for it to turn the engine.

So we need to find out why they are not messing. I would start with putting a wrench on the crank pulley bolt just to turn the engine over slightly. You don't need to go far, just enough to move the fly wheel to a different position.

If this does not work then we need to suspect the new starter is faulty. If you have the old starter and it was working ok, then I would install that one and just see if it starts the vehicle. If it does, you can leave it and return the new one or exchange it and keep it until this starter fails.

Here is a guide that will help with this. It sounds like you don' t need it but others that visit this page may.

Sorry. When you said fly wheel, I missed that this was an automatic.

That is possible that the torque converter came out but normally that would cause an issue when trying to torque everything that it won't actually go back together. Basically the bell housing would sit off the engine and not be flush.

Did you get the torque converter bolts back through the flexplate and tighten the nuts back down?

My bet is still the starter is faulty. Even though it operates when pulled out, does not mean it is able to turn the engine over.

If you have gone to this amount of trouble, I would just throw that old starter on before you pull the transmission back again.

I have done hundreds of these transmissions and starters so I have had that out many times and if you did not remove the converter but only pushed the transmission back, that converter should have stayed in place.

That is great. Thanks for the update. I would not have thought that was going to be in but I am glad you stuck with it and then updated us. Thanks for using 2CarPros. Please come back next time.
