1998 saturn sl. Car would start in the cold, then just quit after a minute. Did this several times. Now wont start at all, just turns and turns. Got a p0404 code for the egr. Fuel seems fine, spark may be a bit weak. 300, 000 plus miles on car. What should the resistance be on the pins of the valve? I only have a book for 1990-1993 (?) model and it calls for 22-45 ohms. Im reading 8. Does this mean the valve is bad? I cleaned it an will try reinstalling but dont know for sure this is problem. Will also try blocking valve ports to see if that works.

Take it off and look at it internally, See if you can move the diaphragm if not then it needs replacement. But you should just go ahead and replace it anyways since it is a 99 it would just be worth it

SOURCE: I have diagnostic codes of

well according to your codes that i looked up for you i think its safe to assume that your timing is off. i will paste the codes so you can see for your self. i hope this is what the codes actually look like.
P0022 "A" Camshaft Position - Timing Over-Retarded (Bank 2)

P0023 "B" Camshaft Position - Actuator Circuit (Bank 2) - See Trouble Code P0020

P0024 "B" Camshaft Position - Timing Over-Advanced or System Performance (Bank 2) - See Trouble Code P0021

P0025 "B" Camshaft Position - Timing Over-Retarded (Bank 2) - See Trouble Code P0022

Check for intake manifold leaks and carbon in EGR pipe and EGR.

====

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.
