Need a little help...
Happens mostly on cold engine,but sometimes also on hot:
engine starts as late as after 3th or 4th key turn.
Excatly-starts for a Nth part of a second and then immediately stops.
When I push alittle the accelerator pedal engines succeedes with starting.
I lately replaced TB -to-intake gasket and by that time also cleaned IAC valve & duct.
Is it a question of:
1.re-programming idle (via known GM's procedure) ?
2.a permanent problem with IAC motor/valve
3.fuel pump
TIA!
