Default No crank, no start, runs when bump started.

First time owner of a c4 and I’m a little lost. Turn the key cluster lights up, security light turns off, and I can hear the fuel pump kick on. Attempt to start and only the seatbelt light on the cluster goes out. Previous owner has installed a vats bypass and an aftermarket radio. The wiring harness underneath the driver side kick panel has been messed with. Tachometer doesn’t work. Attempted to bypass the clutch switch and made no change. But when bump started it runs like a champ. Any help would be appreciated.

Bad starter, bad ground to the starter are the first spots to look

Bench tested the starter and it didn’t do anything, didn’t have my circuit testin tools on hand so I’m gonna check during replacement. Thanks for a starting point.

I think I misunderstood what you meant by “bump starting…” hence what I posted. As long as the start enable relay is working than what you said…

Pushing the car then dumping the clutch, fires right up.
