1990 eighty eight 3.8l. Why no fire/pulse to the injectors?


The camshaft sensor may be bad. Check the fuse for the injectors and it is possible the ECM is bad or the injector drivers more specifically are bad in the ECM .

I have a Mitsubishi gallant cylinder number 1 not firing but spark plug is firing engine misfire,engine check comes on for it to start and it has a hard start help.


If you have spark, but no fire, then check injector for proper activation. If good, check compression. If injector good, and compression bad, possible head gasket, valve, piston, etc.

1998 mitsubishi mirage winding over but won't start I have plenty of spark at plugs I have fuel at the fuel rail .I have power at injectors .should power at injectors pulse when cranking ?


Injectors fire when grounded. The power should be constant.

However, if its not turning over and just cranking, make sure your injectors and plugs are connected to the right cylinder. Also, check your plugs for moisture after cranking. If the plugs are wet, then that cylinder isn't firing. If they are dry and hot, maybe they aren't getting any fuel. Has the car sat for a while? When was the last time it started?

Spark without fire 1992 celica


Not sure I am following your story, but you need compression, spark at the right time, and fuel for the engine to start.
If you know for a fact the plugs are firing, and you have compression, you may not have fuel at the injectors.

Car not starting or turning over indicates towards multiple possibilities. It can be issue with battery or weak battery. But if battery checks out ok, then it can be starter issue or faulty alternator or problem with low fuel pressure or no spark at spark plugs due to dirty spark plugs or faulty ignition coil or injectors getting cracked or dirty and needs to be cleaned.


To confirm the problem, the basic troubleshooting is required.

I had a problem like this on a 1997 VW Jetta 2.0L. I suggest you obtain a multimeter, a gas pressure gauge, and a used injector from a junk yard. You need to find if the car has spark if it is getting gas and if the injector is firing. Plug a used spark plug into say # 4 spark plug wire and ground end against the manifold or other ground. Have someone crank the engine and see if there is spark. If there is spark then disconnect the electrical connector and plug in the used injector and hold in your hand. Have someone crank the engine and if it clicks as the engine revolves the injector is firing. Now if you have spark and an injector that clicks then put the pressure gauge in the upper line going to the injector manifold. Use a T so that the fuel can still flow into the manifold. If these three things check out. You need to also verify the engine is timed correctly and the timing belt did not slip a few teeth. I had a problem with my crankshaft sensor. I bought a new one and although I was getting about a .3 volt ac signal, I still had no spark at spark plugs. I wound up getting another new crankshaft sensor and read 3 volts ac from the new sensor. I then had good spark Hope this helps

Injector pulse comes from Cam sensor, If you have a BAd CAMSHAFT sensor you will not get injector pulse, replace sensor and that should solve your problem. Good Luck and thanks for using FIX YA

Will not start,(but engine rotates)


make sure fuel is going to engine from injectors, you can try by adding carburetor cleaner to intake and crak it, if it runs for a little be then ijectors are not firing, some times the ignition module to control the spark will keep the injectors from firing
