Starting problems

[prowler]

1999 Trans Am, problems starting.

Some time ago when this problem first came up, the car started, I drove away. Stoped the car, and sometimes I was not able to start it again. If I used the remote, locking/unlocking doors, or moving the gearshifter, it would start again, but not always.
But now, it would not start at all, doen`t matter what I do.
The diagnostic shows now; ECU. The mecanic have even tried to start fuelpump manually. Sometimes it start, sometimes not! But not now.
Also tried the spare key, no difference.
Can anyone help me out?

is your security light on or flashing? When you turn the key do you hear the pump prime? If your security light isn't on or flashing and you don't hear the pump prime start with the fuel pump relay in the fuse box under the hood. Just swap that relay with the a.i.r. relay and see if the pump primes.
