Try swapping the ASD relay with the a/c relay.

Re: HELP!!!! fuel injection problems

What's your fuel pressure? Not sure what the spec is but you want it to meet the spec. How old is fuel filter?

Re: HELP!!!! fuel injection problems

new pump, new filter, new plugs, wires, cap and rotor, new injectors, it ran beautifully then just started sputtering and died, wont start again. whoever put the motor in did a extremly crappy job of wiring it, almost all of the wiring under the hood is non factory, im looking into getting a factory harness but not sure how hard that is going to be to change?

I would look at all the wiring as something is not grounded or is shorting out. Or it could be your dist CPS (that fires the injectors) itself that went bad. Unplug the wire harness coming of the dist and make sure the connection is clean.
