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

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?

I have 1993 suzuki sidekick head gasket was replaced then cant get it start has a week spark


If it isn't pulsing right, maybe it is staying on all that time -and spraying fuel like crazy into your cylinders! Come on, Joel, a weak spark and injectors not pulsing right? Get a different ecm and plug it in. Then you can learn the circuits on your old unit and fix it in your spare time.

My 98 gmc 1500 V8 5.0l won't start. Has good spark


Spray starting fluid into the air intake of the engine, if it starts and you have fuel pressure you have no injection or injector pulse as we call it. Check ECM fuse one and two for continuity if it starts with fluid..

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.
