My Pontiac start really nice when the engine is cool, but after drive for a time, and the engine gets hot or i'ts temperature 195 to 200 F. When I stoped, and try to start again with the ignition key, It's imppossible to start only with the key, I need to help pushing the throttel.
Looks when the engine is hot, that or spark or gasoline, or I don't know maybe the inyectors? I thout that was the gasoline and I changed the Fuel Inyection Pumo, with a new original one, but continues with the same failure.
Other question is about the light in the dashboard SECURITY, is always on, but the car is working ok.
Thanks

Start by resetting the security system:

GM PASS LOCK RELEARN- Ignition to "run" position, try to start and let key return to "run" position
Approx ten minutes security light will go off
Turn key "off" and wait 5 seconds
Repeat 2 more times for a total of 3 relearns.
Turn key off, then start it.

If problem persists, then have ignition module tested at most autoparts stores for free.
