Hey guys i have done repairs to my 86 grand prix but seems like everything i do something else breaks. My new adventure is my car wont get any fire to anything! The battery is chargers and all wires are hooked up. I recently changed the alternator and starter on it and after that this is when the problems began! PleASE HELP! I am really trying not to take it back to the shop to get raped over something small.

theres a chance you put one of the small wires on the starter back on wrong. theres 2 small terminals on the starter, put the wrong one on the wrong terminal and the car has no power.
also check the that all the wires on the alternator are in place.

this site is more geared towards the 97 and up grand prix's and w bodys.
your car is totally different platform.
on the up side thats low miles. dont know what engine you got, but if its a v6 you may want to drop a v8 in it. unless its a grand national of course, then you got yourself some thing to work with.
if it has not been ran in 9 years, you should pull the plugs drop some tranny fluid in the cylinders, then grab a breaker bar and socket to the harmonic balancer bolt, and turn the motor by hand a bunch of times, then use the starter to crank it some more, no longer then 15 to 20 seconds at a time, or the starter can burn up.
then pop some new plugs and wires on. check the air filter, change it if id needed. change the oil and filter.
if theres gas in the tank still, that needs to sucked out of the tank, the fuel filter changed, fresh gas added, then fire it up. let it idle for a while before revving it up or anything. the cranking of the engine should have primed the engine oil , aka got oil to the top of the motor, but being its sat for so long let it idle and oil its self up.
depending where this car has been sitting mice may have moved in and chewed wires, that may have something to do with your power issue. so look over as much wiring as you can under the hood and under the dash, if you see a lot of crap packed into a area you found a nest. and mice make the inside of the car smell like crap. you know is mice once you've smelled it before. its nasty.

the 80's 3.8 is nothing great. if the bodys in good shape and you want it for fun, drop a 350 or a 400 cui engine in it and th350 or th400 trans, and have fun ripping up the back tires lol
if your just gonna drive it as is, theres not a whole lot to do to it. just keep up on its maintenance.

More like 106,000 miles, those were the days before xxx,xxx odometers.
Your right it did predate those odometers but ive had this arguement before....this car was owned by my great grand mother.... Who bought the car about 7-8 years before she passed bought car brand new....and care made a few 1000 no trips but most sat due to my grandfather already owning cars....I can also remeber this car being on blocks in yard for years and my gdad would go crank once a week ... So this is my reasoning for low mileage!
