I am sorry for the long wait

make sure the fuel pressure is 7 to 13 psi key on engine off

if it is not the fuel p;ump is bad

if the pressure is good then see if one terminal in each injector connector shows 12 volts with the key on if not be sure the fuses are good

if it has 12 volts at the injector connector and all the fuses are good usually replacing the ignition control module in the distributor should correct this problem
