I have to turn key repeatedly, then wait a couple of minutes then it starts, when trying to start initially, everything else powers up, you hear the click, but the engine will not engage, I believe it's maybe a sensor that sends the signal to the starter. lately it doesn't even have to be cold. It just starts when it wants . CRAZY !!

Has happened any time of day-6am-9am-4pm. (at home almost daily) Then has started in 10 or 20 min. or 90 min.--or?? Sometimes sputters like it's trying to start but doesn't. 1 or 2 times it started rough then smoothed out.Has been at garage 5 days-never failed to start-nothing shows on scanner. No difference using original key (warn some) or new key.

Evap emissions system leak

The pickup truck is an Isuzu i280, model 2006.

Do you have to have vacum hose and or be able to close off a hose when changing the Charcoal cartrige and or the evap vent valve... all these parts are above the spare tire. i can get to them easily...not sure if it is as simple as removeing a part and replaceing it with the new part.

have spent $1000.00 two different mechanics in two weeks and the light is back on again. replaced the evap purge valve hose and electric harness. light came back on after 50 miles. Took it to Authorized service center, they said it is the evap purge valve. No just replaced it, oh ok then it is the canister. ok so they changed the canister, two days later check engine light on again. Seems you could test the parts before replacing all one peice at a time. please help, running out of money.

light problems, radio won't shut off when i close door, rear window leaks, a/c problems

Need to find a vent control valve for the fuel canister.

it occurs often

I am trying to find out where the evap vent solenoid is on my truck. And I would like to know if this is something that I can fix instead of taking it to a mechanic.
They also replaced blower motor resistor and recommended that I should replace blower motor connector, is this necessary?

could someone tell me where the Evaporative vent valve solenoid is located. read one said it was attached to throttle body another said it was back by fuel tank.
