My First Vette
I recently got a 1986 C4 Corvette put a new fuel pump in and drove it home then it started with a crank but no start issue. Since then I have checked the fuel pressure its 42 at the rail and no drop in pressure. I put in a new fuel pump relay also. I checked Injectors with Multimeter and there within OHM Specs also with a Noid lite no Pulsing. Used Jumper wire to check codes only stored code is 46 VATS Anti theft Fault so I got vats bypass and no change in condition. So through Manual,Forum,and YouTube I decided to try the ICM since dont have spark when I use my Inline Spark Tester. My ignition coil is at almost Zero Ohms resistance. Im getting oil pressure when i crank it over. I have good ground and get battery voltage through the fuse panel. The car acts like it wants to start and every so often it would start I could drive it around then park it shut it off sometimes would start back up and sometimes it wouldn't Now for past week it wont start at all. If anyone has any ideas I dont know if ECM is my next step I dont know anyone who has one to try there's.
