fuel problem I think
a couple of weeks ago my 2000 bonnie would not start in the morning almost. but acted as if it was not getting enough fuel.later that day my daughter took it to school and had no problems. it did the same thing a week later. after my son let it sit it started and has been fine. before all this it had a few bouts of rough idling and stalled a few times. this morning on the way to work, on th e-way at 70mph it started to miss a little then a lot until it died. after it stalled out it started again on the 3rd or 4th try, but it was surging while idiling. after it started i kept hitting the gas and it would chug a couple times and then it would take off. I got it up to 70 mph and it stalled about 5 more times within 40 miles. after doing a search on the forum my head is spinning!! I'm not sure if its the fuel pump, injectors, fuel pressure regulator, or anything else that i saw on my search. i have ordered a fuel pump and filter, and i am going to clean the MAF and IAC. I am also in the market for a fuel pressure gauge/tester can anyone recommend a good one that wont break the bank. Any help is greatly appreciated!!

i would suspect the fuel pump or regulator. you would check that by testing fuel pressure. if you dont have a guage they have them at the parts stores or harbor freight. the parts stores will let you borrow it usually if you pay for it and take it back

Pull the vacuum hose off the fuel pressure regulator and smell for gasoline in the hose. If you smell gas, replace the FPR. If the FPR seems okay, you definitely need to check fuel pressure. Autozone will rent you one (I think you get your full deposit back when you return the gage, so it ends up being free). If you want to buy a fuel pressure gage, Harbor Freight will have inexpensive ones. You should also have Autozone scan your car for diagnostic trouble codes (for free) as that will help to understand what is going on. You probably have a P0300 code, which is a random misfire, but a scan will help us to see if anything else is going on.

over reaction!
I'm hoping I did'nt over react by ordering the fuel pump before doing more diagnosis. The man I got the car from had put 2 fp'* in by 145,000. I doubt he ever changed the fuel filter and the car sat for two years before i bought it. lot'* of good post'* to research with! Will check FPR this weekend. fuel pump and filter are on the way. fuel pressure gauge is $20 at harbor frieght. will update the situation as soon as parts arrive! thanks guy'*!

looking for the shrader valve
bought a fuel pressure tester. themotor in my2000 bonni is from a 97 lesabre. the only shrader valve on the fuel rail is at the base of the fuel regulator. is this the hookup point for the gauge? took that cap off and it looked like it had gas in it.hmmm? had time to change fuel filter tonight. hard to blow through the old one, much easier on the new one.
