I'm at a loss. I have NO knowledge about cars but do know that I have a 1995 VW Golf GTI thatwill start SOMETIMES. The engine willturn overbut won't fire. It will do this on warm days as well as cold days. The exhaust and fuel filter have just been replaced. The shop can't figure out what is wrong with it. I'm afraid to go in and start replacing things as I think it can get costly. Any advice would help!!

 

might be a coil

 

or test the fuel pump, its easy just pm me
