fuel pump, or relay?

[Tims_240]

i cant start my car its a 91 350 camaro, everytime i turn the key in the on position i cant hear my fuel pump whine for like 3 seconds building pressure.
and i dumped some fuel in the intake and it started for like 3 seconds and then died, so it is not getting fuel, so is it the fuel pump relay, or a bad fuel pump?
btw: where is the fuel pump relay at? im guessing its the one by the brake master.
thanks alot

start by replacing the relay, if that does not work, then it is the fuel pump.

so we know your pump is not dead, cause it builds pressure like it should.. you should try something cheap first of all.. get a relay.. like 12 bucks and who knows.. it might solve it.. and yes, it is by the brake booster.. its the relay farthest to the left of the 3..

How about something even cheaper, like inj. fuses and filter.

By the way, the security light wouldn't happen to be staying longer then normal wiould it?

YES the security light does stay on, i forgot to mention that

AFI 05 : i dont think it is building pressure, i said i poured some fuel into the intake manifolds, and it obviously gets into the cylinders and fires up. but when i dont pour fuel in, it doesnt start.. so it is fuel related.

im not sure what the security light means, i hope this solves my problem, thanks alot guys, this is probably one of the helpfullest(word?) forums ive been on.
thanks guys.

it means order your copy of 'VATS gone wild' today.

Do you happen to have another key? Otherwise, you could try cleaning up the resisitance chip on yours.

AHH so if you dont hear it whine.. its not starting at all.. i think its either A) your relay, B) the pump itself or 3) the regulator.. could be other things but first things first, before you start replacing stuff... start with relay and fuse.. the fuel pump fuse is by the battery in one of those weatherproof fuse deals..

[AFI 05]

ooooh if you have a VATS problem.. then none of that replacing stuff will be necessary hopefully.. i dont know anything about bypassing or getting through VATS..

sorry man, ive never worked with camaros before, or american cars at all for that matter, i am not sure of what VATS stands for? plz explain, ill do a quick search too.
AFI 05: im not sure where by the battery you are talking about, everyone keeps telling me its by there, but i cant find it, AH!
ill give it another try, infact i might try looking for a service manual to know where everythings at, that would be a good idea.
keep the advice coming, thanks all.

alright, so i looked into the vats thing vehicle anti theft system, and found that the car wont start without the key with the resistor in the ignition, maybe my resistor is bad? would the fuel pump turn on if it was bad? it still turns the car over multiple times...

[AFI 05]

uhh dont know about VATS.. but that sensor. yeah its a little hard to find.. its in the passenger side fender well.. just follow the wires around there and youll find it for sure.. cant go wrong its right there.. not hidden or anything.

vats won't allow it to crank at all, and if the security light goes out when you turn the ignition back off then the vats is fine. i'm going outside now to take a photo of the fuse you're looking for.

[Rally Sport]

Was about to suggest the same thing, but Geno is getting to it..

[Genopsyde]

ok, here's the fuse in its holder located on the passenger side fenderwall.


and here's where the fuse goes, mine is removed for the engine swap.
