82 crossfire starting problems
 

first time here & would appreciate any help yall could give. I have an 82 vette that intermittently primes the injectors. when it does run it idles high & rich.[iacs are wide open I think] check engine light stays on now but I cant get it to flash codes when jumped. ive replaced about every sensor & im thinking the ecm is bad.. again.. any info would be awesome. thanks

I am not really familiar with the throttle body system but you might try cleaning the IAC. I know in the past on previous vehicles I've owned, that has been a solution.
