Was driving and the car died and now have no spark
You will have to prove out the wiring to make sure there are no shorts,
opens, or poor connections. If there are no wiring problems, then the
EEC may be at fault. The crank sensor produces an AC voltage signal that
may be getting corrupted by the time it reaches the ignition module,
due to bad wiring. Make sure to verify whether the ignition module is
receiving a clean strong signal by using an oscilloscope or at least
measure the signal with an AC voltmeter at the ICM connector while
cranking the engine. The voltage will vary with speed, you are looking
for a steady signal that doesn't drop out or become erratic. You can run
new wires, and make sure they are not connected to possibly shorted
sections of the old wiring, by cutting the old wires off at the
connectors and connecting new wires to the cut ends. Or replace the
connectors and wiring if you suspect that the connections are bad.
Inspect carefully for damaged terminals that won't make a good tight
connection with their mating pins when connected.

if you have wiring diagram,start at icm,if not,start at distributor cap and work ur way backwards

Get a T belt from toyota. It has 3 white lines on
it and and arrow mark. 2 lines are solid and one is broken. Put the
arrow facing away from the engine. The cam gears have a dot punched
into them near a certain tooth. This is where the solid white lines
will line up with. The crank gear will have a dot also. It will line up
at 90 degrees from the top, towards the front of the car. This is where
the broken line will match up with. With the belt installed with all
lines on their proper dots and arrow away from the engine, you valve
timming is correct.
Of course you need to remove and compress the tensioner also. I assume you know this already since you didn't ask.

Check your transmission fluid level asap. if the level is good, you will need to inspect the shift solenoids located inside the transmission pan. replace any solenoids that are proven to be faulty. i would also advise to test the pcm/tcm for its operational value as well. this device controls the shifting patterns of the auto trans.
while checking the solenoids, if you notice any metal fragments on the bottom of the pan, this will be a sign of major gear friction. you should re build in this case.

The fuel pump is located in the fuel tank and it can be reached by removing the back seat of the car.
be sure to get a fuel pump of the same rating with the one you are replacing.
Good luck.
