Default 1994 Chevy Blazer 5.7L TBI

Hey all, I've read all possible chats and nothing is what the problem is. I have replaced pcv, battery, spark plugs, ect., in line fuel filter, checked for vacuum leaks, and this truck still dies when braking and turning, also it won't crank in neutral anymore

Any help would be greatly appreciated.

Have you checked the ignition control module and ignition coil?
How about the distributor cap as well?
-I replaced so much on my truck, because I had a similar problem. It was the ignition control module for me (1996 GMC Jimmy)

Keep us updated if it doesn't work. May be something deeper.

Do you have a repair manual? I use Haynes Repair Manual

Your truck dies whan braking or turning?

My 2 cents of thoughts...

Do the dash indications and lights stay "ON"?
How full ist the gas tank?

It has over 1/2 a tank of gas, but braking, turning right, and now backing up, still haven't located the problem yet. And the abs light stays on all the time

No Mr TheJimmyMan, still hasn't fixed it, could it be the EGR valve stuck open/closed?? It's the only thing I haven't done yet, and it's the factory one
