I'd start replacing those black, cracking and leaky vacuum lines, control hoses and sensor hoses with gates rubber silicone ones....and your ECM will get a fair shake with good data from all the devices in question...the fuel pressure regulator especially~
Get the codes read. Write down the code numbers so you know what parts are failing.
