I have a '91 GMC with a 350 tbi. The other day it died getting on the freeway and hasn't so much as attempted to start since. I thought it was the fuel pump but upon further investigation found that it was working and in fact the whole fuel system is working as I can see the injectors squirting gas while cranking. So, I checked the spark and low and behold there is none. I have gone through all of the checks outlined in the clymer manual (mostly ohm checks) and everything checks out as spec'd. But, there is no denying the lack of spark. Anyone have any ideas of what could have suddenly and completely crapped out? I have checked the fuses (unless there are more than those under the dash-I know the fuel pump one was tucked away in another spot). Any ideas on what to else check? I am at a loss. Thanks.
