You need to set your fuel pressure right first. Get a gauge from the auto parts store, they will loan or rent one to you and tell you what the pressures are with the regulator unplugged, also sniff the vacuum line at the regulator, if you smell gas the regulator is bad.

do u have to hold the throttle to the floor to start when warm?

if so based on what youve replaced there is only 4 possible causes

1) short in the injector wiring
2) jitter in the pip signal causing inj to fire
3) bad tune on ecu - look for chip on back
4) bad injector driver in ecu

make sure you didnt get the older turbocoupe injectors by mistake that are low impedance.

Have you run the codes to see what sensor the ECU isn't happy with?
