well i posted my problem a few times before and got a lot of fast responses, no luck yet so im looking for more suggestions. Here are the problems with the car. When it initially broke down i was just driving along and it started bucking and bogging out then dying, then start right back up etc. etc. So since i dont get muh time to work on it the car was sitting for about three weeks. So when i initially posted everyone was convinced it was the TFI, replaced that no luck, so i went with my first idea and threw a new fuel pump in today, still no luck. The car will fire up everytime then bog out after a few seconds.......anymore suggestions, thanks

did you run the koeo and koer tests. change the fuel filter?

yeah go with the tests, but first are you maf, if you are make sure that is working, your probably getting too much air in your intake and not enough fuel...my car dis that when i would take off the plug to the maf when the car was on...

ya changed the fuel filter, yes i am maf its a '92gt, no i havnt run any codes, that was my next step. Can i rent a code "checker"(sorry i dont know what its called) at advance or pep boys?

autozone will run the codes for you for free if you can get the car there. have you checked the fuel pressure regulator?

You could check some of your ignition components like cap,rotor,plugs,and wires,even timing to make sure you car is operating correctly in those areas........I once had a burnt spark plug wire that happened because it touched the headers. It caused bucking because of a missfire on that cylinder. Then as a result the cap and rotor were not good because of the arcing. Just one thought, might not be the answer though.

DIY KOEO/KOER/Cylinder Balance Self-Test no need to spend money in a scanner + check the link for the EFI No Start tests.... don't throw more part$ at the problem, until you're sure they will solve the condition.
