So I've spent the last 6 months rebuilding a f that Hadent run in 6 years due to a blown wastegate.
Motor is freshly rebuilt and put back in, everything plugged in correctly.
Painted the bay so no doubt my issue is grounding but I'm looking for advice.

Ground points:
Ecu
Firewall to uim,
Under uim on block
Block to driver side chassis
Ground wire on harness after starter grounded to chassis.
Ground wire on driver shock tower
Battery relocated so original negative terminal is grounded to chassis as well.
Missing anything?

Symptoms.
Key in turn to run:
Immediate check engine and abs light, coolent level light. Oil pressure light no beeps.
After about 30 seconds I get a constant beep that won't stop till the battery is disconnected, no start, no crank, can't hear fuel pump but I do hear clicking of some sort up front.

I've read about a ground strap from the chassis to the starter bolt? Is this factory? Am I missing it?

Obviously I need to bust out the test probes but I'm looking for any quick ideas.

Thanks everyone.

 

Reading through old threads I realize I never sanded a ground for the grounds near the front bumper support! Will fix and report back.

 

there's also a ground below the lower front spark plug as well, sort of on the side of the engine.

are you sure your battery is good and strong? maybe try jump starting it with another car.
Its normal for the lights to turn on when the key is on but the car is not running.
Constant beep will no doubt be the coolant level sensor.
