car hard to start but starts, runs fine
So I bought a 95 Camaro... $2300, FULL wilwood set up... 6 piston up front 4 in the back... sick brake set up... Car is a 6 speed, obviously a Lt1. The guy I bought it from said the car started great until one day he had the car leaned on jacks to the left and tried to start it, ever since, it has to crank(hold the key for 15-20 seconds) than kicks over, and runs fine...has some check engine lights, but I think due to ABS... Runs hard, burns rubber in 1st and second..So Im not sure, I have heard that the fule line might get air, and you need to bleed at shader valve... Hoping someone can help..

You don't get SES lights for ABS problems. He has to scan it and determine what problems with the engine/tranny control system are turning on the SES light. The ABS has its own light (ABS INOP) indicating problems with that system.
Not likelly to get air in the fuel system. What does happen often, causing hard starts, it rapid bleed down of the fuel system pressure when the pump shuts off. Since the pump only runs for a couple seconds to pressure the system at startup, rapid bleed down will leave you with inadequate pressure.
First step is pull the codes, second step is check the fuel pressure, watching how fast the pressure bleeds down after the pump stops running. Common causes of rapid pressure loss are 1) failure of the check valve in the fuel pump, 2) ruptured diaphragm in the fuel pressure regulator and 3) leaking injectors.
