need help with c4 vette for friend
I joined this site with hopes you guys could help me get my buddy some good advice on getting his c4 running.
He purchased his car about 2 weeks ago from a friend who is a dealer. It ran great the first couple of weeks and some of the things we noticed is the engine is not stock. The rocker covers are taller we are not even sure what engine is in it but it had a aeromotive fpr msd ignition setup larger throttle body and intake custom exhaust etc...etc..
anyway on to the problem once car was warm and at running temps he would loose control of all the electronics none of the buttons worked radio had distortion in the speakers gauges were still lighting up but not working but once car was turned off for a while it was normal operation once it was restarted.
A few days later oil light started coming on when cranked checked oil and level was fine. Engine sounded fine no clatter or anything. Would turn car off and back on and light would go off.
Then it started having idle running issue while stopped at red lights after car was warmed up from driving sometime.
Then a couple of day later car stopped cranking at all
We pulled diagnostics codes from dash display and c 12 was displayed which means no problem.
Fuel rail is reading 42-45 psi pulled one of the plugs and checked for spark and is getting a spark and plugs seem fine not old or burnt looking. Engine turns over but will not start.
We checked all the fuses and couldn't find any that were blown that would relate to starting issue any help would be appreciated
