1990 , no spark at 1 spark wire pull? or all 4? or ?
what about the ignition coil,
got spark there?
is the cam turning? does the rotor spin? cranking,?
if the EFI has power, DC 12v power. and all fuses good.
CEL lamp glows key on, is a good sign, on all cars.
and the rotor turns and the COIL is dead (ignition coil)_
then do the winkyblinky tests.
