May have a faulty air/fuel ratio sensor or o2 sensor, throttle body may need adjusting or have a stretched spring or there may be grime restricting air flow so it's flooding it.

Why isn't it firing?


With engine cranking, do you have spark at the spark plugs? Do you have fuel injector pulse? I can't tell if that fuel pressure is initial prime or not? The initial prime doesn't need rpm signal, no cranking, after that the computer needs to see rpm signal. I saw what you replaced, I'd have to check wiring circuits before replacing anything.

Spark plugs getting wet from fuel, compression ok, not starting, timing ok, spark ok, new spark plugs, changed fuel pump in tank,


Check fuel pressure regulator. The actual pressure with a gauge the clean injectors. I'd double check the timing. It also can be the throttle body. Only so many fuel problems the take a good look at the distributor. Small crack or bad wire gives off spark but might not be enough small 4 cylinder for their pecission motors need to be precise check fuses and main busses those are easy and cheap fixes

Cranks over. But wont start.


Pull the injectors and have them tested for electronic continuity and spray pattern as the needle may be rusted up or the coils in the injectors corroded away for the long period of no use. Regardless of what engine you have if you have spark at the correct time --compression --fuel then you must have go in the engine . Continuing to run will depend on the make and design as the other variables come into play.

1989 astro van turns over will not start seems not getting fuil gas tank full


#1 NEED TO VERIFY SPARK AT SPARK PLUGS # 2 CK FUEL PRESSURE AT SCHRADER VALVE ON FUEL RAIL ,,PRESSURE DEPENDS ON TYPE ENGINE ....IF NO SPARK AT SPARK PLUGS CHECK SPARK FROM COIL WIRE , IF NO SPARK AT COIL ,CHECK VOLTAGE TO IGNITION COIL SHOULD BE 12 VOLTS, IF NO VOLTAGE AT COIL ( KEY ON ) CHECK FUSES THEN IGHITION SWITCH. IF NO FUEL PRESSURE AND FUEL PUMP RUNS REPLACE PUMP .. CK VOLTAGE TO FUEL PUMP WHILE CRANKING . CK USING PUMP GROUND WIRE AT THE PUMP CONNECTOR THIS WILL PROVE GROUND ALSO. USE TEST LIGHT TO VERIFY

I checked my spark plugs and have a spark going to each plug. I changed the fuel pump thinking I didn't have enough fuel pressure. I sprayed some starter fluid in the intake and it started for about 5...


If you are getting spark and the engine tries to run on starter fluid, then you have lost fuel. Check that you are getting injection pulses at the injectors and check the fuel pressure at the fuel rail at the injectors. Check for power to the fuel pump when the engine is cranking, If you get no power to the fuel pump when cranking the engine, check fuses and relays. If the pump is running but you have no fuel pressure, check the fuel filter and fuel pressure regulator and replace any that are faulty. If the injection pulses are missing, check the supply relay which supplies power to the injectors first ( the injectors are earthed by the ECU) Disconnect one of the injector plugs and using a test light (buy one from a auto parts store) clip the end to a good earth on the vehicle body, switch the ignition on but dont start the engine, then probe the two connections in the injector plug. One of these connections should be active all the time with the ignition switched on. If it is, you may have a sensor failure (crank sensor etc), if it is not, check fuses and supply relays. A word of warning, the wiring you are dealing with is connected directly to the engine control, if you make a mistake, you can cause irreparable damage so if you have any doubts, take the vehicle to a professional..

My 1986 Toyota 4x4 won't fire up


you will need to drain the fuel in the tank and replace the fuel filter and plugs after a couple years the fuel will go bad and it will plug the filter and foul the plugs if you do those 3 things and in that order it should start it is important even though you have good fuel pressure that you replace the filter to prevent damage too your injectors

Continues cranking. Wont turn over. what s my next step?


You mean it cranks but wont start (cranking and turning over are the same thing) When cranking, rap on the fuel tank, if it then runs, the pump is bad and will need to be replaced.

I have fire and fule I just replaced the spark plugs and redid the timeing and it still wont start what ellse can I do?


are the injectors opening? fuel pressure doesn't mean the injectors are delivering any fuel to the cylinders, does the system have any trouble codes? if u are not sure if the injectors are getting a signal buy a NOID tester from NAPA or a tool dealer like Snap-On, it is very easy to use, plug it onto the fuel injector connector and crank the engine, if the injectors are getting a signal the light will flash, it is kinda hard to see so do it in the evening, if the injectors are not working then check to see if the computer has power, if the computer checks ok then u may have an issue with the engine wiring harness, very common on this car. also make sure the timing belt is ok.
