Hello and welcome to Just Answer

this sounds like there's no power to the ECM?

as this will turn on the fuel pump,

if the car will start using a squirt of quick/ easi start into the intake then this confirms the problem is lack of fuel and the ECM is getting power but its not reaching the pump or the pump is faulty

check the ECU power is present by measuring voltage at the fusebox and on its relay socket if OK then check the wiring and connections to the crank speed sensor for damage / chafed insulation

. Check that its relay switches in and out and the relay contacts are clean and bright – replace the relay if in any doubt and do the same for the fuse
