do you park on a steep incline? could be a fuel pump issue or a check valve issue that keeps pressure in the lines when the pump is turned off.

 

Nope the car is parked on a flat surface. If it was the fuel pump would it still be able to start an hour or so later n part of the time? What do you mean by check valve issue?

 

typically, fuel pumps have a valve that holds pressure in the fuel line when the car is off. if the valve is faulty, pressure may drop between starts where you will need to crank it over for awhile to build up enough pressure to start the car.

but this is just a guess, it may be a completely different issue. it could have something to do with the ignition system, but we'll let someone else come on and elaborate on the possibilities there.

 

I see, ok thank you for your imput. Any ideas help to try and get me going in the right direction.

 

How many miles on the car? V6 or I4?
Do you have any codes coming up in the car?
I had that happen once were it would not fire, but it was becasuse I got a new key and it was no programmed to the car. So I programmed it. But mileage would help alot.

 

I also got this. MY dad is a mechanic so he told me this... "Ignition coil, Igniter or Distributor. Pull a spark plug and plug it back into it's spark plug wire. Turn over the motor and see if there's spark. You might need a helper or do it at night. There should be a small blue spark in the spark plug gap. Don't touch it. No spark...bad. A lot of Toyotas use the same igniter so they are cheap at the junk yard and easy to fix. "

 

On an older vehicle yeah. The 02 and up camrys use a distributorless ignition system. It's coil over plug. So 6 cylinders= 6 coils. Highly unlikely that all coils have a random no spark issue. Use a DVOM and check the resistance of the cam position sensors. And crank position sensor to be sure they're in spec.

 

42,000 miles and its an i4. No codes are coming up on the car. You think it could be the key not programed? Would a bad programed key allow it to start sometimes n not others? I will try the spark plug tonight or tomorrow. What is a DVOM?

 

If it starts once in awhile then its nothing to do with the key, But I would check with a DVOM ... IDK if you bought xtra warrenty with ur car, check it out at the dealership. The best way would be to actually see the car.

This is a DVOM
