Hey everyone, I have a 97 Chevy K2500 5.7liter engine. I took my crankshaft position sensor off to test my buddies(same engine as mine) vehicle which wasnt getting spark. When I put my crankshaft position sensor back on my truck, I was having a crank no start issue as well. Which it was working fine before that. I thought maybe buying a new crankshaft position sensor would solve the problem but it did not. I have read about the relearning process for the CKP, however from what I gathered, is that the vehicle should still start just will run rough .Any ideas recommendations what to look for would be great.
