Changed timing chain and gears now not getting spark.Have new coil pickup asd relay and coil but now cant figure this out..I have A 92 3.9

 

Any check engine light codes? Did you mess with the crank sensor? Do you have correct fuel pressure? You did line up the cam and crank timing marks correctly right?

 

Also be sure to check the ignition/fuel pump splice under the PDC

 

Never touched crank sensor.No codes.I finally got spark now(bad distributor)but misfires something awful.Checked 3 times to make sure everything was correct before putting it back together. Has new cap rotor cam sensor plugs wires coil.I found spraying brake cleaner in throttle body makes it run smooth soon as I stop it misfires again.Checked all injectors and all are working.Im lost!

 

How is your fuel pressure and volume sounds low since adding in extra "fuel" helps.
