oops I missed this.
"blown 15A fuse under the FI slot"
that blows only if the Fuel pump shorts.
and fuel pumps love to short , old.
or the wires to it are shorting out. sure.
or the last owner shorted out the FUEL PUMP relay socket (testing done wrong, call hot wiring it dead wrongly)
and one guy here did that wrong and blew up the FUEL relay transistor in the ECU. (then the relay is dead FP)
normally.
The FUEL pump relay closes for 3 seconds each key on if does ECU and relay are happy.
3seconds is the priming pulse, so rail goes to 41psi, primed , thus less cranking to get it to start. (2.0L has unique pressure, my 41 is based on older engine)
