crappy fuel pump? Please Help!!
 

hey, i have a problem with my 88 gxl. first let me say that my cats are extreemly clogged. but that will be fixed. but the problem is that every time that i turn left whether it be soft or hard the car bounces in lack of fuel or spark. my dad said that it could but the fuel pump not getting enough fuel because of a not baffled tank. this sounds correct because the fuel pump is on the left. but it happens when full or low on fuel. please help it is rendering my rx useless:mad:

when was the last time you changed your filter?

i just got a tune up and they were supposed to do it but i will do it my self. could that do it

first of all ... is the car all stock?

well, the filter would not cause your starvation problems only in turns, it would be everywhere, but especially at the higher RPM. i only mentioned the filter because i figured it would be best to start off trying to find your problem, knowing that your fuel system is healthy. did the car sit, undriven, for any period of time?

to be honest, i'm not sure why your dad would talk about fuel tank baffles. did you do something to your tank that would alter it in any way? besides, you said that it happens whether it's full or low ... so i'm definitely a bit curious as to why he would say that. the stock tank must have some sort of baffle system or surge tank system to compensate for cornering. unfortunately, i can't speak that intelligently on the fuel tank of the Gen II cars ... so this may just be a load of crap ...

it may very well be the pump about to shit itself, but that still would not explain why it only happens in left turns ... now does it? i'd start simple, like checking the wiring (the pump, the injectors, etc.) to see if there are any loose connections that may loose contact under the loads of a left turn. if they all seem fine, then maybe drain the tank and have it cleaned out ... could be rust water or rust flakes. however, don't condemn the pump until you've exhausted all the cheaper possibilities first, because in my experience, EFI pumps usually just crap out without warning, so if the car is starting at all and it revs out smooth and clean, then i would not suspect the pump just yet.

the car is all stock except for a k&n drop in filter which i just cleaned. but thanks i will start small then go big

well ... change the filter and make sure you take note to see if the gas coming out of the old one is rusty.

ok
