the thing is that the car was running yesturday when i took it to the exhaust shop. it just wouldnt rev past 3k due to a bad maf ground. so when i fixed that problem and took it out on a drive it shut off and wont start now.. the car was running on some iridium ngk plugs that came with the motor from japan. i bought the same ones and put those on.. should i try running some other ones? fuel pressure gauge reads correct, but when i crank i can smell fuel.. thats why i dont think there is spark.
