T350c finally back together, won t start!
Discussion
Well it’s taken 5 years to get my t350 assembled and this has the shine taken off, as it won’t start.
Turns over, immobiliser seems to switch off.
The dash board lights up and seems to work eg oil and water temp 25c but no oil pressure after cranking. There is an error message think it 11.
The fuel pump is running all the time no spark at plugs. Connection to ecu comes back with “no connection” or some such.
This did run when dissembled but has been extensively rebuilt over the last five years, I’m looking for suggestions for further investigation,
Are there any volatile memory/ battery items?
Should the pump running all the time?
I am tending towards sending the ecu away, any suggestions to expertise?
Any way, I would appreciate your collective thoughts on my problem

The priming you hear when turning the ignition on is the power steering pump, not to be mistaken for the fuel pump. Are you sure it's the fuel pump? Then the relay might be stuck on.
Can't remember if the fuel pump primes when turning ignition on but it should only prime for 2s max.
After that it won't and shouldn't run as long as the crank isn't turning.
The ECU registers this via rhe crank sensor.
Therefore you should first check if the connector is properly fitted to the crankshaft sensor.
If it is, pull it off and clean its terminals with chemical contact cleaner. Measure the resistance between the two terminals on the sensor itself. If you measure 0.x or a larger than 2kOhms resistance it's broken.
Check the fuse too and then have a helper (or long leads to your multimeter) check if you get 12V to the fuel pump whilst cranking.
