what would cause my throttle to not respond while the engine is running?
switched 12v i press throttle and it responds, when it starts i get not throttle

i talked to the guy who did my harness also and i have a hard start issue it wont start till after a few tries. he asked if the check engine light is on or off when i try cranking it over and i told him it turns off. what would cause the computer to loose power?

as far as the throttle i know its the right pedal tac module b/c the guy ran my engine with all my parts and it did indeed start.

i tested to make sure my switched 12v is getting 12v while cranking with a test light and it is, im kinda lost at this point? what would cause this a bad ground maybe i dunno?
