what have you gotten done on your blazer today?
I hate not having more tools, and a better place to work on things, Replaced the cap and rotor today, still not starting, all fuses are good, coil is good (have a spare I swapped it out with) ugh.. still no spark
get your ICM tested
your talking to a person who has bad luck with them things.... It got to the point I got 2 spare delcos around.. Funny enough both my 4.3 and 350 take the same icm so Im good for a while
Need to get an IAC this week. Truck went crazy after I fixed it today. Took foot off the pedal and was slowing down, all the sudden the RMP's skyrocketed and the truck started to accelerate like crazy. was hard to stop.
Was able to some how make it home (were only a few blocks away)
Checked the throttle cable ect it was all good. Started the truck and it skyrocketed again, Shut the truck off, immediately thought IAC.. took it out, Cleaned it, and the truck is running fine now.
With it being that crazy today, I am just going to get a new one.. I cleaned it about a year ago also.
