When you manage to start it next time, put your foot on the throttle and hold the revs at approx 2-2500rpm straight after it has started.

Does it cough or splutter?

It's propably a vacuum hose come off or split

If not then it could possibly by either dirty or contaminated fuel or a blocked air filter/fuel filter

[SMW]

I was just thinking it could be a fuel supply problem which you could eliminate if it stays running on a bump

[SMW]

A bit of Googling gives me . . .

1.Vacuum leak

2.leaking EGR valve

3.Air filter / fuel filter clogged

4.Fuel pump not delivering enough fuel

5.Leaking head gasket

6.Timing belt

7.Camshaft lobes worn

8. ECU

if i keep my foot down it still cuts out, fuel is getting in nice, air filter is new, had filter off and on but still will not run with or with out and toyota will not help with out seeing it. thanx for the help but i think i am flufed.

i have 2 more avensis 1 Rreg and 1 Sreg and want to take the ecu off one and try that but don't know if it will lose its memory???????????????

Check your vacuum hoses for splits or just swap them from your other avensis.

[micky3]
