Question about 1987 Chevrolet Blazer
The battery and starter works.lights fuel pump heater everything shut down.
Look for a broken fusible link at the starter power power terminal. Not easy to get to sometimes. May be able to apply power to a power link on the firewall. Look for the thick red wires.

It's that infamous "chip" in the key that becomes a nightmare to many. The security light may or may not start flashing. Sometimes it stays on steady. Gradually the car begins not cranking anymore or if it cranks it will start and die in a second. They have been known to shut down cars while driving and create dangerous situations. Randomly it will do this more and more often until it won't start anymore. VATS, PASSkey and Passlock immobilizer systems are killing cars all over North America, they have a short lifespan and are certainly more effective against owners than thieves. Here is how you save your car
QUICK FIX TRICKS
1st trick, Try a spare key that is newer or used less. The pins wear down with use and so do the keys causing the security to fail.
2nd trick, (if not starting) turn the key forward 2 clicks till right before it would normally start, leave like that for 10 minutes. ( no less ) After 10 minutes, turn key back then forward and your car might start. I did this in my regal for more than a year. If its shutting down while running, I'm sorry I have no quick fix...
There are 3 parts in this system.
1.The chipkey (Black resister chip in key)
2.The lock cylinder (Pins that read the chip in the key)
3.The TDM (Theft Deterrant Module-Sometimes called the "computer" or "brain") This allows your car to start or continue running depending on your type of system.
If any of these parts fail or are not quite funtioning properly in the slightest way, your car will not start, start for a few seconds, or die while driving. There are partial "fixes" out there, you can bypass the key and the lock cylinder in the stearing column which means ripping apart your car for a temporary fix. If you are going to do the work yourself, i suggest pulling the whole "computer" (TDM) out completely.
NEVER WORRY AGAIN FIX: Bypass the whole VATS/Passlock/passkey I or passkey II system entirely. Literally take it out, and throw it away. I just did this in my Regal. Took about an hour. It took longer to find the "theft deterrant module" so i could remove it, than it did to actually wire in the "Bypass module" from Newrockies. They sell a unit for 200 bucks to totally bypass this system FOREVER. Life time money back guarantee. Finally did this in my car. Well worth the 200 if you've looked into getting this replaced at a dealer. It can cost anywhere from 600-1000 bucks. And beleive me they will sell you all 3 parts before they "FIX" your problem. Dont go to a dealer, do it yourself. You can study up and purchase it thru this link.
-----> http://newrockies.ca?ap_id=judd0081 ----- With this fix, you can take that whole Vats, passlock, passkey system out of your car all together. If you want more info on how this system works, click on that Newrockies link and scroll down to the last link on the bottom of the home page. "The VATS/PassKEY/Passlock Bypass Tutorial" This link explains exactly what is happening and why. Once you understand how this works, you're going to be pissed at GM but happy you found Newrockies.
It works for:
Any GM, Saturn, or Isuzu Vehicle with VATS or PASSKey or PASSLock security systems.
If your car has the chip in the key or in the lock cylinder, then you can save it with this Full Bypass.
