Re: 2001 4.3 S10 wont start

gchemist: no, just checked for spark on a couple cylinders, spark was not really blue/white, was more orangeish, of course battery was somewhat discharged too. got to charge the battery up so it'll be 100%. Pulled the coil wire and was getting strong multiple sparks as engine turned, but have not did the ohm meter test yet either...just got it friday night and weathers been crappy since. did sprayed some ether and pored some fuel down the TB but forgot to unplug the mass air sensor so didnt get anything when we cranked it. from what I read if the hat is off the TB and the mass air is still pluged up the ecm wont fire the coil or ignition module since it thinks there is no air available to the engine? will need to recheck as soon as the weather breaks! hooked up the OBDII scanner and no codes stored. have not checked the EGR....are they known to give a no start condition? have had them plug up before with a chunk of carbon and it would load up, run rough and set off a code imeaditly.

thanks for your help!!
