Cold Start Problem

[andy750]

Hi all,

I have a problem stating the avensis when its cold and when hot! I've changed the fuel filter thinking that would solve the problem,but no. If I just start the engine it just cuts out, If I start the engine and apply a few rev's then it runs fine even on idle. Anybody had the same problem?

Cheers Andy

hello Andy

check with :

SCV;

MAF sensor;

bleed an air from filter.

check with an DC coming from from alternator. The idea is that both SCV may "play" due to voltage is variable -- and either pass or not diesel to the pump. Cheers

Could you tell me what SCV and MAF means? The filter is fine as I've done a good few miles in the car since the weekend

-SCV -- suction control valve

-MAF -- mass air flow

the filter is fine but you cound remain an air inside

Hi,

How would I know if these parts are faulty, as I've not come across these parts before, being this is my first Toyota?

Thanks Andy

-SCV -- suction control valve ---> the idea is to have the coil resistance measured + compared with manual. In case you have deviation then SCV must be changed on new one.

-MAF -- mass air flow ---> it is sufficient to just clean it (located on the throttle)

- fuel filter --> the filter case /lid has an air escaping plug or bolt aimed to escape an air. You can screw it off on 1/4 of circle , turn the key in ON position (without starter)--> bleed the system using a membrane knob on the lid. Once you can observe a real diesel without bubbles coming from this air escaping plug/bolt then it must be re-tighted.
