Nissan Elgrand Running Rough, Starting & Power Loss Problems

I have replaced all spark plugs and 4 coil packs it’s still the same

When pulling away from a junction there is a complete loss of power as if the accelerator pedal is not connected

I serviced my electric pump and it's not pumping fuel into the engine it's only being stuck in the head

Constantly beeping and wondering if it's an electrical issue warning

I was fixing the petrol gadget but the car produced uncontrollable misfiring, I checked all plugs are okay, I changed 3 fuel pumps, plug cables are responding well and nozzles

The car has stood for a while due to the Covid lockdown. I went out to start it the other day, but the steering lock won`t release. I have tried all the wiggling the steering wheel from left to right, and squirting in the key hole with WD...
