4.3 ltr nightmare
Ok, 4.3ltr blazer. When cold, start's and idols
fine. You can accelerate slowly and its fine
but if you try to rush it, a total lose of power.
This is while still in park. When its warm,
sometimes it won't even start and if it does
you'll get nothing over ideal and more times
than not it will die. Thought it was the spider
injection system but was wrong. Thought
maybe ignition, wrong again. EGR, nope. Idle
air control, not so. Checked cap and rotor.
They were fine. Went back to fuel , maybe
lose of presure, nope. Code reader is
showing a ground code and high output on
coil. Someone please, if you have any
suggestions feel free to do so before I go
bye a gallon of gas and have a bonfire.
What is your actual fuel pressure? A ground code is something that needs to be addressed, a lost ground can make all kind of strange things happen. High output on coil can mean that you have bad plugs and or wires or the system is too lean.
