So about six months ago I hit some tire debrie on the highway took out my radiator. I had it towed to a firestone and they replaced the radiator. After I got it back I suddenly started having problems with it starting, it would turn over but not catch, had good power but would sputter and cough but not start brought it back to shop they said I had a bad ECM and replaced that got car back worked ok for about two weeks started again and then my car started to overheat. Back to the shop and they said bad thermostat and that my starting issues had something to do with fuel pressure that they say was possibly having issues due to my aftermarket alarm and remote starter (which I've had for 5 years). So basically now if my car is parked on any upwards incline it won't start. Any ideas????
