You need air/fuel/spark to start a car check to make sure your getting all three. While cranking did you pump on the gas pedal ?? Could be a fuel problem since your getting spark but don't do it too much you don't want to flood it. Also check for check engine light codes (since your obd1) jump te1 and e1 with a paper clip and put the key to "on" while counting the blinks of the check engine light to determine what codes you get.

Make sure you battery is not dead too if the cars been siting for awhile.

i'm leaning more towards fuel pump issue more than anything

is there a way to access the fuel pump or to see it without dropping the tank i had a jetta a while back and it was under the back seat is that the same for ours??

its under the rear seats.

get a fuel pressure tester and see if your getting the right fuel pressure at start up. This test will do more good then just opening up the fuel pump.

im sorta new to 6th gens but i know on some toyotas you can jump the fuel pump via a connector or something under the hood

[presure2]

i doubt its the pump, but you can check it by using a peice of wire to bridge the FP and B+ pins in the diagnostics box in the engine bay.
whens the last time you did a tune up?
do you know how to verify the timing belt is still connected? (pull the distributor cap, verify the rotor is spinning when you crank the engine.)
if the belt is still good, you can verify timing is correct by setting the crank pully to 0, and check that the rotor is pointing at wire #1 or #4.

at the diagnostic connector, FP to E1 will kick it on.

hey pressure dude thanks alot....i did the FP and the B+ and the car turned right on. what does this mean and what do i need to change?? can it be the relay or is it the fuel pump?

[legalkid86]

Pressure:

Now thanks alot now that i guess this has got me somewhere what would this mean the car turned on doing the FP and the B+

heres the link of the car turning on

fuel pump relay.

[Bitter]

fuel pump relay.

or wiring to the fuel pump, or wiring to the fuel pump relay, or the circuit that activates the fuel pump relay, etc.

well guess what i changed the efi relay cause that is the only one in the fuse box nothing else has fuel pump replay on it, but idk it still does not turn on can you guys tell me what else to do and now i did that bypassing" now it does not turn on at all....i got another problem now help me out what else can i do??

[Bitter]

iirc isnt there a green circuit opening relay behind the radio console thats part of the fuel pump circuit? i only have diagrams for a 7afe corolla on hand, should though be similar to your 7afe celica.

i'm seeing efi relay, clutch pedal/park neutral switch, circuit opening relay, several grounds and several power feeds. all needs to be checked.

well buddy i still got problems now, guess what happened well i went to autozone bought a efi relay thinking that maybe the fuel pump relay had something to be related to it, it didnt work. when i changed it out now the weird thing is that i tried to bypass the fuel pump in the diagnostics box now it wont turn on at all and well i tried to do check for spark by getting someone to crank it and screw driver in the plugs to a ground and now i dont get any spark at all, now guys what can i do can it be my timing belt that maybe cause this problem keep in mind the problem i had before as well , please help me out guys thanks....
