It takes time to turn on

Hello everyone I can help me; I have a problem with a Voyager 3.3 Model 94, the problem is only in the morning, it does not turn on after two or three llavas, the ignition is erratic and stabilizes only throws me a code 27 I do not know what this code refers, I have noticed that there is no land on the injectors when starting the march only after two or three attempts, I hope you can help me solve the problem, before it is appreciated.

Look to clean the spark plugs or heaters and but change them that cost almost nothing and improve

Czech in the injector connector that is a 12VOLT Fortive for 2 seconds when opening the Suwicht

Code Name: 27 Injector Control Circuit
Moment of Verification: With Batteri´a voltage of more than 12 volts, excited automatic stop rely, amplitude of pulse of the
lower injection to 10 ms and less than 3,000 rpm of engine speed.
Establishment condition: between 0.64 and 10.0 seconds are required to establish this co -set when no
inductive blow 0.18 meters after deactivating the injector and without any other activated injector is not detected.
Operating theory: Fuel injectors are high impedance solenoids controlled by the PCM. ASD's relief
supplies the battery voltage. The injector activity time (pulse amplitude) is controlled by the amount of time that the PCM connects
to the mass to the injector control circuit. By varying this amount of time, it is allowed to flow less fuel through the injector.
