Basics, always works. they are.
1: good engine?, (compression over 150psi cranked w.o.t)
2: good spark , got spark to all cylinders?. (a simple test)
3: fueling good. (not too lean, not flooding)???
from 1920 to now, all cars running on gasoline.

i can advice a simple test for each, non are complex. or costly .

if spark is good, and test fuel fails (spray)?
i bet you skipped #1 ,

here is a guy running a gas motor with no fuel in car. period

see?

he is a human carb. here.
just keep eyes away from the induction ports , in case it backfires.
dont 1000 of times by me.

one other tests is to (EFI) is to kill EFI (pump relay pull)
and start car on test fuel.
this helps prove engine was flooded and runs. like above.
also the opr.guide told you to clear floods with
WOT, wide open cranking, this tells tells the ECU to cut fuel 100%
to clear any flood, this works on all cars.

The pump should be running and producing fuel when ignition switch is in the on position.

Yes the points on the relays need to be clean. If the fuel pump does not turn on when you turn the key on the relay is bad.

HI my 1993 toyota supra its a twin turbo 2jze engine wont start it was fine when I parked it 2 months ago.....the first time i started it started then shut off right away.........now when the engine...


Hi lovebtngu,
First thing to check is the ignition system. Spark plugs, coils and distributor/rotor. If all ok then go to fuel system check if there is gas coming out. If no check the filter check the fuel pump.

84 toyota supra 5 speed man.


sounds like ecm. car starts but when it switches over to run setting from cranking setting the cumputer ecu doent activate the run curcuits which may control your fuel injectors. check to see if engine has spark. remove one plug wire from spark plug put it close to the valve cover if you see an arc then you know that you have spark. then also go to fuel pump in tank and check voltage on the power wire if you have good voltage and the pump doesnt make any noise while ur cranking then it may be a fuel pump if the pump is making way to much noise then check the fuel pressure by hooking up a fuel pressure gauge. all test are to be done while someone cranks the engine. noid light for the injectors, disconnect on injector electical connetor connect the noid light to the wire that u just unplugged from the injector. the light will flash while u crank , once it goes to the run circut the light will either stay on which will shut off ur car or the light will stay off which will do the same. if the noid light did what I said when it went to the run circut then it is what controls your injectors...ecm good luck....daniel
