fuel system shot?

[emeny2]

i have a 92 camry with the 5s and about a week ago it started to hesitate or stall when i try to accelerate. now just over the last few days its been a pain just to get it to fire up. cranks fine but no start. any sugestions?

Sounds like your going through the same thing I am currently going through, my gen3 would almost just like stall but the car would still be running just not moving when it should be. Than after a few weeks it would crank fine but not start.

We have been playing with the fuel pump thinking it was the problem, but it was fine.
There are 2 relays involved with the fuel pump, the EFI Main and the Circuit Opening relay (behind your glove box); we checked both of those and they were working fine.
There are also 2 fuses under the hood located with the EFI, they are called EFI 15a and AM2 30a those were also fine.

So now we are looking for corrosion underneath the relay connectors, and if its not either one of them we are guessing the computer is broken.


I’ll be sure to keep you updated if we make any new progress

actually i replaced the fuel pump and the car fired right up. but it still hesitates when given full throttle. thanks for the other info tho i will keep that in mind for future refrence.


hehehe spoke to soon. i have basically replaced the entire mechanical end of my fuel system so now im trying to get a diagnostic computer hooked up to see wtf if going on in the electrical side. i was telling someone what was going on and they said that it sounds like the car is getting starved of fuel? if anyone else is having similar probs any help at all is welcome. im not used to working on cars cause im a heavy equip mech.
