sparks weak... spark has to be blue ...

what brand did you use for ignition products ?

these trucks prefer ac delco ... you can also use ngk plugs in these motors

Will not start!!
 

looking for some help. 99 blazer 2wd ran great, never had a problem with it. drove to the end of the street and made a turn...motor shut off. will not start or even try to start. starting fluid wont even make it stumble. has a fresh tune up, brand new fuel pump, erg, ignition coil, and distributor. checked the spark and its orange. what am i missing???

i put bosch in it. i prefer ngk. but thought these would be better. are they crap?

well bosch plugs. everything else is ac delco

Yea never knew i had a time machine mod ?

any ways just playing its a forum glitch that should be fixed soon

other then that I dont think the plugs are the blame for this problem like mr fog said

Pull dist cap look close at it and rotor.

Bosch plugs.. one topic sure to unite Ford and Chevy lovers.. they suck. Not the problem here, though. They just tend to misfire.

my last post is on top again wtf

Gio, do you have a time machine in your semiBlazer? It looks like the first response to the OP was 3 minutes before the thread was created. Pretty impressive.

i got a couple distributors. ill try them and see what happens. i know the timing chain could be replaced too. ill see if this makes a difference.
