Re: No start backfire through intake
does it have a crank sensor at the balancer?
if so then its probably failing faulty
what is fuel pressure at key run position prime up time?
check ground wires if there are any at the thermostat housing
check for any small bad wires around battery or junction block
cables clean dry and tight at all ends
any bad ecm fuses
MAF failure is another one, if so equipped
try firmly tapping on it, see if any change
and if there is change in it when doing this the next time it is running then do replace it
make sure air intake ducting is all intact and no leaks
it may not start if not all intact and tight
if all above checks out then see how much slop wear is in the distrib, it may be sloppy erratic signal, enough to prevent starting
also security system?
clean key and key tumbler slot real good with cleaner
