    Sounds like a spark issue or electrical problem, need to check to see if you got fire at the plugs.

    On these could be many things so a electrical meter ..and fuel gauge will help a lot. Could tell you to start changing things ..waste much money ..so diagnostic be way to go..no magical fixes...welcome to the forum.

    No fire,no fuel,lights on dash wont come on unless I charge it all nite with trickle charge then starts one time for a few sec.dies turns over just won't start I was wondering if it could be anti- theft system.

    Its something electrical cutting power to everything, it could be the security, can be reset.

    Try the security procedure...But only thing security does cut fuel pimp off.


    There is a relearn so if the computer lost the programming some how or if a component was replaced it can be reset, the process is below.


    1. Perform a security system relearn. 2. Let the vehicle sit for more than 10 minutes with the key off. 3. Attempt to start the engine, leave the key in the run position monitoring the security system indicator. 4. After 10 minutes, the security indicator will change state. 5. Turn the key off and wait 10 seconds. 6. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on. 7. After the second 10 minute timer has expired, turn the key off for 10 seconds. 8. Attempt to start the engine. If the engine stalls, wait another 10 minutes with the key on. 9. After the 3rd 10 minute timer has expired, shut the key off for 10 seconds. 10. The security system will relearn on the 4th starting attempt and the engine should start and run.
