Kind of a weird problem because my car ran fine before i put it away. The car trys to fire but wont start throwing codes p0201 p0202 p0203 injector circuit open on cylinders 1-3 but never cylinder 4. the plugs are new and is getting spark, there is injector pulse, the resistance on the injectors checks out fine and the resistor is bypassed. i replaced the cam position sensor with no change. the fuel system was done by rs in Minnesota. If anybody has an idea or has ran across this type of problem before any help would be appreciated!

 

Disconnect fuel supply line from fuel rail,let somebody crank it and watch if you getting fuel.

 

Is this on 91oct or E85 ? Take the injectors out and spray a little bit of wd40 and just a bit of air through the injectors, theyre probably clogged.

 

I'm on 91 and definitely getting fuel

 

are these high impedance injectors? i'm assuming so.. since resistor is bypassed?..how long was it stored for? I'd try to get new fuel...

 

How do you know without seeing it?do you smell unburnt fuel when cranking?

 

I'd suspect old fuel based on the circumstance but those codes sound like an electrical problem in the injector circuit.

 

There's a fuel pressure gage on the rail I have the injectors out gonna try that...at worst I can see if the code follows to cylinder 4 when I put a different one in there

 

Ok I tried blowing a bit of air threw the injectors and switched them around when i put them back and still no start and the code did not follow to cylinder 4. Im thinking the the the ecu witch is locked or the COP ignition control box

 

Injectors are no good try to swap your stock ones and see if it starts up

 

Mice?

 

Depending how you store your car it sounds like you had some critters visit your wiring harness.

 

I really don't think so the injector wires run into about a one inch loom with what looks like a billion wires and everything else is working

 

Bad fuel, bad injectors? Could any critters have gotten in it and chew up the wires?

If bad fuel is your cause you might wanna look into cleaning her out.

 

I driven mine maybe once in a year with e85 in the tank.took the battery out stored it in the trunk during winter.when I was ready to start up again charged it over night.after two or three cranks fired right up.is your battery good?
