I have a 96 vette that won't start

If your vehicle is factory should have electronic multiport fuel injection, and would have a fuel pump located inside the gas tank with the sending unit to the fuel gauge. also check fuses and relays first before removing tank. and ensure that you have spark before checking fuel, unless you know that spark is good. oh i this is of course if the vehicle is cranking at lease, if not start with the starting and ignition circuits. hope this will help.

99' Corvette will not start

If it's been sitting for a year without being started, I can almost guarantee the battery is dead. At the very minimum you are going to need to either have that battery charged or replaced. I would replace it if it was me, I'm not sure it will even hold a charge after that length of time unused. If the alternator was working properly before you parked the car, it's probably still ok. Nice car by the way, I had a Torch Red 98 Vette and now drive a 03 Anniversary Red Vette. Good luck.

Have been reading the reports on the idle and starting problems on the '89 Vette, and that is the problem we are having also. We've checked the timing and vacuum leaks, etc. etc. Need to try the advice for...

I also have an 89 corvette that had the same problems.Ill tell you what fixed my problem. I also changed the fuel pressure regulator(its under the plentum in front of the distributor)This was not the problem but I replaced it anyway. The problem with the idle was my injectors.The factory multecs that are in there were original to the car and are not compatible with the blends of gasoline that are sold at most stations.Too much ethanol. I replaced mine with a set from fuel injector connection.(FIC) They are rebuilt with a three year warranty. Thats better than new ones. They are bosch 3.The car has run perfect every since.As far as the long starts it helped that too but if you do a little research on the 89 corvette youll find that GM put some crazy software in the computer that year. It requires the engine to turn over two times or about 3 seconds before the injectors fire.Thanks and good
