Car will not start, replaced the clutch last night. No spark, has fuel.

There was a connector on the front of the block by the bell housing that we looked at but it was okay

Follow the wires from connector and check them as well, make sure ALL grounds are reconnected... Go back over your work, It's MORE than likely something you (or the installer) have created! .. Just so we're on the same page... Transmission IS in the 'back' of the engine! .. So is the *second* crank sensor...there are two crank sensors... the other is in FRONT of the engine where the crank pulley is ... passenger side..
