Cranks but no start (STARTER REPLACED)(OBD SCANNED)
Hi my 2009 lancer ES starter blew a couple weeks ago and had no crank so I switched the starter myself and got crank but no start I OBD scanned it and I have Fuel,Spark,CCM,MIS but says no air EVAP,O2S,HTR and egr is not working anyone no the issue
Those are just the tests the car run. They mean nothing unless the car is running and trying to pass emissions.
Are you sure you have fuel? Fuel pressure.
Are the injectors firing? Test light to one of the injector pins.
Are you sure you have spark? Sparkplug in pug wire or coil toughing bare metal on the engine.
All other fuses are good? The ones relevant to ignition and computers
Hey I switched my spark plugs as soon as the starter blew thinking that was the reason and it wasn’t I haven’t tested the plugs for spark yet which i will do ASAP and I have 80km of fuel inside my tank you think I should check my fuel pump I checked all engine fuses and nothing was blown
Check spark first.
If that is working that means the computer is reading the sensors on the engine to calculate the spark. Thats a good thing.
The fuel is not about what's in the tank but if its being sent to the motor.
Sound test: Remove gas cap, put ear next to filler neck, have someone turn key on. the pump should run for 15-20 seconds to prime the line.
If you hear it thats good.
Now go to the fuel rail and loosen one of the hoses bolted to the rail. DO NOT HAVE KEY ON
There should be "3"
The little one is a vacuum line. Ignore that
Theres 2 left
Slowly crack one of the fittings and see if fuel comes out.
you should wrap a cloth around the connection before loosing the line to keep the fuel from spraying everywhere.
If a theres pressure fuel will spray. If theres not it will dribble out or the rag will not get wet.
My battery should be fine and the key turns and cranks but just no start I’m testing my spark plugs out today I tried testing my spark plugs on a piece of metal and even my battery and no spark.
so this last test today should figure things out on the spark side I’ll probably try starting my car with my moms car battery too see if it’s juice cause I once was disconnecting my battery and my 3/8 socket touched my battery and made a mark on the silver tip

So I tested my spark plugs today with a spark plug tester and found spark but 1 of the 4 is losing all its spark and has a tiny bit even at 4000 rpm volts from the tester would that 1 bad spark plug stop my engine from running

I tested my fuel pressure and got nothing and sprayed at me when I released it but not even a drop hit the towel no gas coming
If there's no fuel then you'll have to start with the pump.
Find the relay, jump 30 to 87 and see if it runs and builds pressure
Other thought that just occurred. did you crack the connection on the regulator or the feed.
If it was the regulator side then you probably wont have pressure because it is a drain back to the tank.
I’m not too sure it might be regulator but while I was attempting a lot of starts my battery got drained and went and got it charged now the spark noise came back I think it’s the fuel pump I found a used one that I’m going to pick up and test
So I just switched my fuel pump and trued starting my engine and not my fuel is leaking and no start any help ?(ALSO BROKE ONE OF THE 8mm blots sealing the FUEL PUMP )
