    hello Tanya,

    I've been trying to figure out what can be wrong with my car. The cars starts and runs but only for a moment. I've changed the fuel pump, filter, temp sensor, changed air flow meter, and throttle postion sensor. It is still giving me the problem of not wanting to keep running. I followed the test in the manual and still nothing. The thing is giving me 23 32 codes indicating the air temp and air flow meter. Is there anything that Im missing, is there a relay that can be the problem? HELP Please

    I'm not very familiar with either air temp or afm issues, but you can try the online TSRM if you haven't already...

    could possibly be a bad EFI relay too, does it click when the key is turned to ON?

    Well I went back to fool with the car some more. I so happened to spray cab cleaner in and the car started, then stopped. I had my brother spray some more and kept sprying, it ran like it did before all of this. Its getting fuel, the fuel pump is new and working, new filter. It could be a relay, could it be the circut opening relay or the EFI main relays.They're in the engine compartment fuse box right?

    Yes the relays are in the black box under the hood.


    It can't be getting fuel if it's starting with carb cleaner. Somehow it's not getting to the injectors. Check to hear those relays click. Also, there's a yellow check connector by the AFM, use a paperclip or something to jumper it out, turn the key to ON and put your head near the intake manifold in the back, you should hear fuel going through the return line. If no noise, I would listen under the gas tank for humming, sound of the pump actually running.

    I jumped the pump already, it's working. Im looking at the relays, circut open relay and the two efi relays. Is there a way to jump a relay once it is unplugged?

    yep, when I was having EFI relay issues of my own a few years back we did this




    and it worked like a charm.

    UNLESS, the problem causing it to die instantly is too much air due to an unmetered intake air leak (after the afm), in which case the extra air now has extra fuel and the engine can continue to run as long as this extra fuel/carb cleaner is applied to use the extra air, otherwise it dies from too much air relative to the amount of fuel supplied.

    That is a great list, Tanya.

    One of my pet peeves, people who prime there fuel pump without knowing (cycling the key) when the car still is still in running condition, then wonder why the car is flooded and smells like gas.

    ah, that would have to be a pretty large vaccuum leak I would think to cause that... should be able to hear the hissing when it's running off the carb cleaner I would imagine
