Real Problems With 1995 Bonnieivle Pls Help!!!

Well I Had The Coolant Sensor And The Therostat And Oil Changed Friday The Car Has 153,353 Miles Now, I Got It When Is Had 144.000 The Car Ran Well And Cooler Fri And Sat. I Thought Is Was Fixed But This Morning I Stated It Up To Let It Warm Up Is Ran Fine After About 6-7 Min When I Put It In Reverse And Mashed The Gas It Died, And Hasnt Cranked Sense, The Moter Will Turn And It Will Run For About A 20 Sec. But When I Mash The Gas It Will Die. If I Feather The Gas Pedal It Will Run But Skip And Never Catch Up It Will Also Make A Popping Noise And A Little Smoke Will Come From The Motor, It Sounded Like Some Bad Gas But I Really Dont Know,i Just Had Filled The Tank Up In Friday, The Car Ran Perfected Until This, What Should I Check Or Do First? Please Help!!!!!!!!!!

sounds like you maybe need a tune up, could be a couple spark plugs not firing, or could even be one of the coils, i had a buick lesabre that did the same thing, turned out to be the coil pack 100 dollar part fixed the problem, but i would definitely check plugs/wires first, could also be a plugged cat. converter

WHen things happen on a sudden after some messed around , look about the things they touched. Make sure all connectors are secured in their right place. ANd......sorry for that...but did you actually see them put oil back in the engine, and screw the plug in (in reverse order..lol .)? Just check the dipstick... This happens........
Suspecting water in the fuel is not so weird....it happens too...I got that in my furnace heating oil tank last week, and the burner did exactly what you describe...siphoned the water out, got the flame back.
ONce these simple things are checked and proved wrong, will be time to look for more.

i just put new plug wires in it about 2 weeks ago the thing will crank and run for about 10 sec then it will quit or if i touch the gas it will quit also,,if it wasnt firing would it not run at all,,,?? if i keep pumping the gas is will run skip and pop inside the air blower filter. i need al the help i can get,,oh yea i did check behind all of the work i had done,,,

OK that looks like very lean mixture: very possibly a problem with MAF sensor but I would not jump on that immediately. I would first check FOR SURE that there is no problem with the engine coolant sensor (why was it changed? is that the 2 wire coolant sensor - the one for the ECM - or the single wire coolant sensor - for the gauge?) . Reason is this: I have modified MY coolant sensor circuit so it tells the computer that engine is warmer than real. This saves A LOT of fuel in cold weather driving, BUT it will not let me start the engine when cold - too lean a mixture - if I do not switch the "correction" out for starting and maybe 30 more seconds. (has no effect once REALLY warmed up) . A short circuit in the coolant temperature sensor circuit would tell the computer that the engine is VERY warm and that would lean the mixture to the point it might not start. OF course, Georgia is not as cold as Quebec , but since someone played around that sensor recently, I'm always borne to think it might have a relation with the problem.
Best: disconnect the coolant sensor and make sure there is no short circuit in the leads and leave it disconnected and try to start: an OPEN circuit tells the computer the engine is VERY cold...thus rich mixture. Tell me the results.

i checked the fuel pump pressure it is noe nearly putting out enough pressure to keep the injectors working, the pump is pumping but very weakly,how do youy replace the fuel pump??

oh yea one more question where is the fule pump relay located???

hey yall it was the fuel pump, it was pumping but not with enough pressure. this problem is done!!!!!!
