Reset system by removing one of the battery terminals.

Look for smaller coolant lines coming off the back of the block or going into the firewall pretty sure it's in the dash

The module may have failed.
The module reads the chip in the key thru the sensor in the lock cylinder.

Change the thermostat and start from there.

If it starts for 5 seconds out less, and you notice a security light on the dash, go to this link for answers. Gm are notorious for failing antitheft systems http://vatspasslockpasskeysecurityhelp.yolasite.com/

Does your car have a little black chip on the key?

You may have removed the fuse for theecurity system. When you turn the key to start, does the security light start to flash? If it does the security system will need to be reset. Most GM's reset is to leave the key in the run position after you try to start it. It usually takes 30 min in this position to reset. Some times you need to try to start it and leave the key in the run position for 10 min, off and back to the run position for a total of 3 times and on the last time its off go straight to start it position. I have found it by googling resetting security system venture van. Good luck.

I had that exact code a couple weeks ago. Mine needed new oxygen sensors. They(there are 2, only one was throwing a code, but I had both replaced) cost a little over $100 to have replaced.
