The engine gets heavy when you want to start it

Hello, how are you

for the year, unquestionable that your car is Fuell Injection, so possibly the theme is for a short or damaged sensor
under the helon is the diagnostic connector, you must locate the connector and bridge terminal A and B, the board turns on the light of Chek Engine, it sometimes blinks a long one is 10 and 1 short is 1, so you add how many long signs and how many short signs. Two long is 20 and 2 shorts are 2 It is equal to 22, the fault code is sought and how much to give you the relationship of codes, if you get 12 it is that the vehicle is normal and it is not electronic failure but mechanical failure

greetings

Greetings Tech, engine beauty, here in VZLA it is used by the Century Buick but the majority arrived without a flow sensor, I think this model brings the module of 3 coils on the side, this module is initially independently independent when starting the vehicle, that is, omit Internal faults, also test the CKP sensor wiring, which is not broken somewhere and very close to some heat source. Tell us how it went. Luck.
