ok. been trying to figure this out for awhile now.. replaced fuel pump and still wont run... i figured out that if the cold injector is connected it runs for 2 secs then dies, if i disconnect it, it wont run at all... traced it back to the injectors... they have the 12 volts key start power... but they are not firing... how can i find out if the computer is bad? i tried to check for any signal coming from the computer and there is none.... its 16052541 out of an 85 tpi i believe(the guy who sold it to me told me it was out of an 88 L98, im still pissed lol)

another thing.. the chip inside says HLK if thats needed

thanks
