i tried to get help with my car on the lt1 and computer diag part of the board and have struckout....so if anyone at all can help locally my car is not running and my nerves are about shot... you can contact me here or by phone---469-446-4639 thanks for any help

 

What is the problem your having?

 

Yeah, why is it not running? More info please?

 

car will start and shut off the fuel after 5 seconds---tried brain in another car and it works fine...optispark is still sparking after fuel is shut off because i can spray carb clnr and it will still run---it gets nice blue spark. i pulled fuel injectors and stated car with them above the intake to see the spark continue and the fuel stop on all injectors at once. i am speculating at this point that the vats system is somehow shutting down the fuel after 5 seconds. if the opti was bad the signal to run the sparkwould also dissappear...i still get good spark just no fuel. i am not sure how to get around vats at this point but i have to get this car running...it is taking way to much time and screwing with life and work. it is a 94z28 standard trans.....i pulled some datamaster files with the trial version but i cant look at them and no one has a scanner to look for codes.
thanks for any ideas or help and i live in frisco by 121 and preston

 

try freescan, if you can use datamster you should be able to use freescan to pull up the trouble codes.

It works with obd1 Fbods

 

if it is your VAT go to a local shop and have them turn if off.

 

I'd check the fuel pump too.. I'm betting you've tried that too though.
