So i recently replaced my driver side exhaust manifold with bbk shorty headers because the stock one cracked. Car ran fine before install but afterwards my ccrm began buzzing when turning the key to ON. So far in the search of the problem ive changed the spark plugs, fuel pump assembly and filter, alternator,battery, ive checked all my fuses aswell. Last night i changed the crank and camshaft position sensors, i just ordered a ccrm on ebay, will that fix my problem? Is there anything i havent checked that i should? I know i have fuel pressure so im ruling out fuel as a problem, could i not be getting spark? If anybody has any advice or coule point me in the right direction id really appreciate it thank you all.

Also before the install i was getting two codes, p0171 and p0174. After the install im not getting any codes whatsoever even though the car wont start, figured that’s something to include.
