Question about 1990 Pontiac Firebird

1990 pontiac firebird wont start

Ok i just got this car last sunday. it ran fine,
bad thing was its been sittin for a year, exp. tabs and is due for emissions test. so ive been running it five minutes a day as it spits carbon out lol,
one time while reving it i guess it clogged and it wud not idle and died. it then would not restart for 10 minutes, once it did it would not idle. later on in the night it was rough but eventually idled very smoothly.
i can not drive until this monday when i get my license.
today it was scheduled for a tune up so my mother was going to drive it.
withtin 30 seconds fo starting it she reved it.... now i wish i broke the law and drove it there.... it now will not start. jumpstart does nothing. when u turn the ignition, it makes the sound that it normally makes when it starts (only difference is, now thats the only sound it makes, instead of makin it for .5 seconds and starting, it just makes the noise non stop) it did this this morning, over 14 hours ago, still will not start.
co workers said u can find a repair manual online, i cant find any for free, this is my first car so i dont kno too much lol. im not completely stupid im not a blonde woman ( not seriously i know blondes kno cars too) im jus an 18 year old dude whos never worked on a car. PLEASE HELP!!! i cant get this thing to the tune up unless it starts!
o and fyi its a great car and ran perfect when i got it, it just needs cleaning after the first few minutes of running the exhaust is fine theres just build up inside somewhere its not like the car from transformers lol

    ok i dont have tools neighbor does, and actually knows how to do it properly i see the spark plugs dont kno how to take em out looks like its in a case, its too dirty and way to cold out to work on it thanksgiving day so ya will have his help sunday. ive taken apart and replaced a fuel filter on a suv once, if its in same spot on this car its gunna be hard to get to considering its 6 inches of the ground rofl. anyways i will be looking into that, if i ca change those 2 parts i can save prolly have the labor on a tune up rofl. anyways ya will get that stuff fixed soon, the middle sparkplug when i took cap off had corrosion on it like a battery terminal so thats definately one of the issues and the gas filter is pretty reasonable so it will be swapped thanks country. any more advice anyone? or does anyone kno where i can find a free service manual? i got bucks for parts not for books and dont wanna wait for delivery anyways id rather tow it into a shop for that price

    Sounds almost like my 90 Firebird. It quit running the day after I bought it. First replaced the plugs, plug wires, distributor cap, fuel filter, and air filter. Rotor fell apart as ti was being rmoved. This got the car back to idling. I bought a Shop Manual and a Code reader. Using these. replaced the fuel pump (old one below specs), oxygen sensor, injectors. Now it was running but periodically speedometer would drop and engine would buck with no codes. Took it to a good mechanic and he finally determined by eliminating all other problem sources that the ECM was bad. As of today I've added 180 miles with absolutely no problems. Good Luck!

    Because the car was sitting for a year, you most likely have a problem with the gas going bad. After attempting to start, remove one spark plug, check to see if the tip is wet with fuel. If not, it could be the fuel filter is plugged up. This is something that should be replaced anyway, since the car sat for so long. Good luck w/ your 'bird!

Check out eautorepair website. You can purchase access to repair info for a car for 1 week $11.99, up to one year $29.99. It's a car repair manual on your computer, don't have to wait to have it delivered. It can be a bit technical, but would be a big help to you. You'll save way more than that fixing some stuff yourself, so it's worth the investment, and u can print out info u need to bring outside to the car. To make sure I understand what's going on, when u turn the key, the engine turns over, and it won't start now. Just turns over? Keep me posted as to how u do this weekend, I can help out more when u have more info on what u find then.

2002 Pontiac Firebird acts like it ran out of gas and now won't even start. Could it be fuel pump or something else. Service engine soon light also comes on occasionally due to emmisions sensor fr


with the key on engine off listen to fuel pump,if you can not hear the pump winning ,the pump is bad

if you can hear it,it might be working but create enough pressure
you can rent a fuel pressure gauge from auto store and check the fuel pressure

95 FIREBIRD 5.7 WONT START HELP PLEASE?


did you jump the timing belt cogs on the belt ? if it jump'd that would cause it to not start or them pesky control modules under the rotor sometimes even the pickup coil / did the power wire fall off the distributor terminal ? there should be plastic shrouds you can take off to peek at the timing belts (5.7 ohv) see if it's shredding apart and time for new 1 / if it did i hope the valves didnt hit the pistons / they bend it's bad . average life of a timing belt is 80,000k or so many years .

MUTIPORT FUEL INJECTION PONTIAC FIREBIRD 3.1


My 92 Bird with the 3.1 did the same thing after it sat for about 2 months. The car had aways started right away before. I had to jump start it and I thought it would never start.Same as yours after it started. Seem to get better after I ran it awhile. It was getting good spark and was getting fuel. I checked fuel pressure, it seemed to be within specs.then it started to sputter and the pressure dropped to almost nothing. Seems that the fuel pump was going bad, but still would pump enough fuel at times to run. When the car was parked the fuel pressure would bleed off, and when I tried to start it the pump had trouble pumping enough fuel to pressure the system.Long story short! Replace the fuel pump, and filter.....
