I have a 1990 toyota camry dx.fuel pump relay

The fuel pump is suppose to be buried in the middle of all the float assembly. You will need to pull it all out of the tank. You will need to disassemble the float mechanism to remove the metal cylinder in the middle which is your fuel pump. Here's a pic of what you are looking for. In some models it is located about a foot further back in the tank. According to the MFG these have been like this since 1990. Look for the item in the attached photo and you have found your fuel pump. To check the fuse and relay for this fuel pump. Try checking the fuse/relay box under the hood of this vehicle. Look at the UNDERSIDE of the relay box COVER. Toyota calls this relay a "C/OPN" relay

I know, , experience talks.
we buy new belt and the clerk gabs abox
1: wrong belt in box, last customer returned it like that.
2: clerk gave you wrong box used wrong engine table(GATES)
3: you told clear wrong and he did it wrong.
4: learn that some engines even same 1.6L displacement had 2 head types that year. or series of years.
my car here, has 3 belts sold for it, 2 are wrong, per above.
no belt brand told just 164 code (gates?)

OP never told it is a toyota , nor the year, wow no year.
3s-fse =1987 to 2000 year made. no car model told what can go wrong, answer ALL. that.
DOHC engine 2 cams. CR = 9.8 (3S-FC, 3S-FE, 3S-FSE)
2.0L engine 1,998 cc, 121.93 cu-in
step one make sure both belts new and used, laid top of each other have same number of teeth and pitch. (viewed) if not WRONG belt.
OOPS? (the new belt can be touch tighter.,old belt stretched be longer or even a wreck)
some models have VVT, in the head and may change the T belt USED, no car told no year, no VVT told.
1990 turbo?
1990 camry is gates T138
1990 turbo T125

if you buy a belt for the wrong 3s-HE engine you fail
learn what is there, first, under hood. exact engine
turbo or VVT or what, make and model and year not old.

The fuel pump is controlled by the "Circuit Opening Relay" It is located under the Engine Electronic Control Unit (CPU) which is under the center of the dash.

what a Pain.In.The.A..................................................................................

The fuel pump should run for a second or two when you first turn the key on, but then shuts down to prevent the engine from flooding if the computer does not get a signal from the crank or cam sensors which the computer uses to trigger the ignition system. So no spark no fuel. Check to see if you have a spark in the ignition system.

Pull the distributor cap and allow time for drying or used light compressed air if available.

checkout the crank sensor and the engine timing also checkout these websites www.autozone.com and www.alldatadiy.com

Fuel pump relay is in the engine compartment left side fuse block

just an idea... install a free-flow air filter like a K&N brand filter for example & then get the air flow meter adjusted again... if you can afford it, a shop with a dynamometer & performance tuning skills will be able to do the best job for you. there may be a user-adjustable ECU available for your model so you can set it up for economy by you as needed too...
