freinds car is only running on cylnder 3 and 4. 90 dx. mpfi swap.

all plugs are sparking. the spark plugs are wet with gas. i dont kno what the problem could be

 

Firing order correct for your plug wires?
Double check distributor wiring.

 

sounds like firing order is off.

 

yea i think its the fireing order also. but the fireing order is correct. new plugs and wires... will checc the dizzy wireing. any more sugestions

 

chipped or bent valves

 

did you just do the dpfi to mpfi conversion?

 

the valves looked good before the head went on the blocc

 

yes

 

did you check the Injector wiring? pull the injector plugs off the injector, and then make sure there is power, if so then make sure that you have it wired up to the ECU properly so the ECU is grounding the injector so it sprays.
