Also my check engine light is on but when I hook up my scanner it won't link to vehicle
Expert:  Tim's Auto Repair replied 1 year ago.
ok
tell me,,do you have a fuel pressure test gauge?how much fuelpressure do you have at idle and when giving it throttle?
thanks
Customer: replied 1 year ago.
I don't have a fuel pressure tester I'll have to either get one or borrow one
Expert:  Tim's Auto Repair replied 1 year ago.
ok..
get one and test the fuel pressure,,these must have no less than 60psi at all times..from the way you explain,it sounds as if you may need to replace the fuel pump..it sounds as if the pressure is too low,,so test it to confirm
thanks
