well my daughter took the gn to school and when she came home the gn died and would not start, check the spark, and has fire, it has fuel, and got it started for 1 minute and and then died again, keeped on trying to start it and fouled out the plugs, and smelled like gas, and some gas came out of the exhaust, was wondering if anybody has had this problem before, put some new plugs and still did not turn on. could it be the cranksensor, or any ideas would be great, and put me on the right direction, appreciate any input?????
well got the grand national running and its running like crap, gave me some codes, like the coolant temp sensor, replaced it and still the same, then i replace the ignition coil, and still the same, the module looks bad, the clear silicone stuff is all light brown and sticky, so im thinking of replaceing the module but im not sure, bad module would the car start. and the car is smoking black smoke and rough idle, and smells rich, and when you accelerate the car still rough idle. appreciate any input.
 
If there is goo on the module...

I think if the goo on the module is melting there is an internal short in the module heating the potting material up (the goo) and it is seeping out. May try another module if someone close has one before you buy it.

Just my thoughts,

how's your fuel pressure regulator?


i have had fpr diaphragm leaks on my old tuneport cars and mustangs act exactly as you describe (except for the coolant temp code..???!!??). appearantly the vaccuum port was sucking raw fuel right into the intake. Just a thing to check. if you get a mouthfull of gas when you suck on the fuel pressure reg hose its a sure sign..lol.

my second guess would be a maf crapping out. Did you have a MAF code??
 
checked the fuel pressure regulator and seems to working good!!! but the mass air flow, don't know will check it tomorrow, thanks for the help! the car has 33lbs injectors conley chip, bigger fuel pump with hotwire kit. just thought the module goes bad and no spark, but will let everybody know when and if i get this car going again, appreciate it.
