EF9

Hey everyone i have an LS in an EF. i put the motor in a while ago and i cannot get it to start on its own. If i spray starter fluid into the IM it will run until it burns off but for some reason it wont STAY running, nor will it start on its own. I have changed (4) sets of injectors. The car is MPFI has run b4 i put the swap in with nothing different other than a motor, same harness, same injectors etc etc. i have spark, i have fuel, and i have compression. please someone help TIA

Does it turn over but just not crank? Make sure your firing order is correct... and timing.

If it will run with starting fluid it sounds like a fuel issue.

are you running an aftermarket regulator or a stock one?

when you turn key to run, do you hear the fuel pump running when the check engine light comes on, if no then main relay or the ground on the thermostat housing is loose. if yes, while you are cranking it do you hear the fuel pump, take the distributor off, leaving it pluged up and rotate the shaft with the key on, you should hear the fuel pump run and injectors clicking. if not the distributor is bad.
google and honda-tech are your friends! this has been covered thousands of times, just sayin.
