99 GA SE V6 3400

Once in a while my GA won't start. It takes several tries to get it going.
Sometimes starts with no problem at all. Runs fine when its starting OK
When it doesn't start, the engine light flickers. No other lights when it runs OK.

I've replaced the plugs, fuel filter, ignition cylinder and the computer.
After the last time in the garage, computer was replaced and it ran OK for 1 week.

Please ideas

Thanks

You said the light flicker but does it register any codes?.

That flickering light sounds like an issue I had.

After getting new wires / plugs, while driving, my RPM's would hesitate severly / drop, and the SES light would blink. It turns out it was just that my wires weren't seated properly. I pushed down really hard on all the wire boots, and the problem was solved. Does your GA hesitate or sputter when driving? If so, you could have an un-seated wire.

While driving along the car drives perfectly, no issues at all. Once in a while it dies, than I just start it again and it goes fine again.
I have no idea ofwhat's going on, all the obvious it's already replaced.

Ideas Please!!!

Thanks

There was a code related to security, then they replaced the ignition cylinder. I never had the security light comming on though!
Thanks

I am going to say partially plugged injectors or injectors solenoid that are burned out.
