Reprogram computer of 2001 chevy venture

I am seeking to reprogram the computer of a 2001 chevy venture. i have changed the heads, and put everything back together... yet it still does not start. only backfires. unhooking the battery posts doesnt work and the only other solution i have heard is to use a scanner... however, i am looking for a more inexpensive avenue to this problem.

    we.., here is the situation as it stands...

    i bought new pushrods and rockers. the venture was running before i tore it down. when i got it, the heads were warped... but i had them resurfaced. FINALLY... i put everything back together... but it just wont start.

    what would be helpful is if you could send me a pic of what exactly the engine and it's system look like.

    i do know the basic set up for it all:

    EX (long PR) IN (short PR) EX (l) IN(s) IN(s) EX(l)--- on one side

    EX(l) IN(s) IN(s) EX(l) IN(s) EX(l)--- on the other

    hopefully this adds a bit of clarity to my situation for you. i GREATLY appreciate the help you are offering.

    i saw your posting this morning , it caught my attention because i have been working on a 2001chevy venture all day , so while i was in the manual i did look for how to reset the pcm , and i didn't post a solution because the site was up & down and i do need more input from you . you've had the heads off , did it run before but a blown head gasket or something ? if it backfires , in a way thats a good sign you won't need to mess with the pcm , if you had immobillizer issues you wouldn't get the back firing , but the bad news is possible problems would include firing order , weak fuel pump , or push rods on the wrong lifters , there are long and short rods , so tell me you got the firing order correct , and the push rods back exactly were they were , and let me work up a solution for you . thanks

How do I disable security system on 2001 dodge caravan

Check your mechanics manual. There is most likely a sequence of times you must turn your vehicle on, then turn the key back one click. you can actually hear the module trying to reprogram itself. If a vandal was at fault and damaged anything, you may have to take it to a mechanic. My daughters Chevy Venture was stolen and destroyed. Little by little we put things back in etc. I was not able to reset the system, and had to take it to a dealer. Still cheaper than a replacement van though. Good Luck! :)

Why 2001 chevy venture van wont start in the cold.

Look at the ignition module or the computer. Taking off the battery cable resets the electronics. Have a diagnostic done on it to pinpoint the problem.

2001 Chevy Venture hard to start and grey smoke.

In the older cars, before all the emission laws added so much electronic garb, black smoke meant a fuel problem and grey smoke indicated a problem with internal engine parts like piston rings. Hope this helps.

The security light is on in my 2001 chevy venture message center

Hi there,
Most commonly with these cars the security system will do this if the battery is "drained" while trying to start the car. ie: a low battery that is too weak to turn the engine over. Usualy the power options & accesories will not work if this is happening.
To fix it you will need to ensure the battery is charged, you then disconnect the battery negative cable for about 1 minute with the key out of the ignition. reconnect the battery cable & start the car normally. Everything should be back to normal.
Let me know if there is anything more you need for this concern.

2001 chevy venture lost key

You must get a new key from the dealer. Bring in the registration, and photo I.D. Then they will cut you a key. After that, try this procedure....
  1. With a master passkey III key (Black), turn ON the ignition, with the engine OFF.
  2. Observe the Security telltale, after approximately 10 minutes the telltale will turn off.
  3. Turn OFF the ignition, and wait 5 seconds.
  4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes.
  5. With a master passkey III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password.
  6. If it does not work, you will need to get it to the dealer.
