Check the fuel pressure at your rails and compression in your cylinders.

2003 kia floods..no start hot


How do you know it floods? Fuel injected vehicles should not over fuel the engine unless an injector/fuel pressure regulator is leaking internally or the computer commands a high injector pulse rate based on sensor information. Does it have spark and fuel pressure when the no start condition presents itself?

98 toy sienna no spark no injector pulse coil and injectors have b+ but they have no ground signal


Dont worry about injection the rule of the is the same, correct for spark and establish it and fuel will come for spark you will need to trouble shoot CKP(cranksensor) and your ICM . The crank sensor is a alernating wave form and the ECM will only see its tope voltage and frequency or RPM, If the signal doesnt generate a good healthy signal ,your ECM will not give fuel injection pulse. The second problem you may be faced with ICM ,this include the Ignitor, its at the left strut tower, for now no spark I would start he trouble shoot at the cranksensor this include the terminalonnection and the toner wheel itself

Why can't I get spart. Don't have injector pulse.


Loss of injection pulses usually means a loss of an engine timing signal or even the security pack preventing the vehicle from starting.
You need to check all the timing signals, crank angle sensors, cam angle sensors etc and ensure that any security is disabled or turned off.
Check for spark, if you have spark but not injection pulses, then its a timing signal issue. If you dont have spark or injection pulses, also check the ECU (the cars computer) although I do not know of any issues with this make and model.

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..

88 cavalier has no spark


you need to start somewhere. get hold of a scanner and see if car has a crank signal. the crank signal supplies refrence for both base for ignition and injection pulse. if it has injector pulse and no spark, look at the ignition module/ coils but if has neither look at the crank sensor or harness to the module

Not starting


Hook up a fuel pressure guage, the start and run fuel pump circuits are seperate, see if after it starts the pressure drops.
