Hi . I have a 1991 GTA 5.7lt auto.. the cars suddenly started to stop. No Pulse to the injectors.. the Coils ok.. wiring around the dissy is ok..
. can it be the anti-theft module....

Car decided not to work at a gas station.. just pulled up.. it was fine.. then nothing.. .. then about 5-10 minutes later it started.. I did pull the hose off the throttle body.. but just put it on to check the butterflys were opening etc..
Car started.. then drove the car about 100 miles.. no problem.. but then did not want to restart.. took 3 goes.. then went . so I took it home..
Then when turned off at home.. it did not want to start and has NOT since..
I have changed keys.. to two others and had the keys checked . .they were all consistant.

.. any ideas.. before we look to the anti-theft module....???
thankyou

(PS.. car has 20,000 miles on it original)
