i have a 89 cherokee with 4.0ho and it is getting spark, getting fuel to the fuelrail and the injectors are new. for some reason it wont run on its own, however it will run on starting fluid.
any ideas??? b4:explosion
 
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.
