Hello, I'm christophe from France.

I'll try to explain in english my problem.

This morning I finish to install the new heater core on my 92 blazer S10.
When I put back the autoradio and tried to plug the antenna... I put it in a wrong hole... and touch a wire inside the autoradio.
I heard a "clac" who makes me think... "a fuse"!
In fact, the radio fuse was dead.
I change it and checked all other fuses.
But until that, the chevy absolutely refuse to start.
Starter work, engine turn... but don't start.
Is there a fuse somewhere I don't see?
Is it possible to break the ECU or ECM??
Does some one have an idea to help?
thanks very much (and sorry for my english)

 

help

 

Did you double and triple check all connections that were disconnected during the heater core removal/install? Your ECU is in that area..

 

Thanks for your help...

I've not disconnected anything except the radio...
But I will check on the ecm if something is not disconnected.
thanks again.

I've found something...
I put some fuel directly in the injection body... and the chevy start.
So, it is not the ignition.
Maybe the fuel pump or the ecm??

could you help me to determinate where is exactly the fuel pump relay on my 1992 S10??
I have relay under the hood, relay in the fuse box...
If my problem doesn't come from the relay or fuel pump... where looking for??
thanks and sorry to insist

 

If fuel into the intake allows it to start, you definitely have a fuel delivery problem.

The fuel pump relay is located on the firewall. I believe it is located near the brake booster and should share a bracket with the A/C relay (if equiped) with the fuel pump relay being the one closest to the left side of the vehicle.

 

Hi there,

Just some news...
Yesterday morning, I tried again to start the blazer... and he started.
I don't understand anything but...
Thanks a lot to those who helped.
