Long crank before start...no codes

[qiksho]

Well I finally got home again to work on the SHO.

I ran the codes again...this time doin the koer test also (last time car wouldn't stay running long enough)

KOEO
Current 539, 551
Stored 336

KOER
116 ? What is this? I can't find it
538
632

Cylinder balance - 9

I am assuming 538, 539, 632 were my fault running the codes.

But 336 - PFE sensor signal is/was high?? What is this and how do I clean it or replace it.

116 - ? I can't find what this means on midwestsho or shotimes??

551 - IMRC solonid/circuit? What am I looking at to solve this? SHOTimes calls it a IAS circuit failure which is what??

Thanks guys
Brandyn

Try the Dali Design link in my signature for testing procedures and code descriptions. Here they are:

The "116 (O,R) Engine Coolant (ECT) sensor out of range" code is the engine coolant temperature sensor (ECT) out of normal testing range. Recall that the test assumes that the engine has warmed to normal operating temperature. Was the engine temperature below 50F?

The "336 (O,R,M) PFE sensor signal is/was was high" code indicates that either the exhaust system is plugged (check for rattling cats) or the DPFE sensor on the rear of the intake manifold requires replacement because the electrical portion has developed a problem.

The "539 (O) System shows voltage at PCM pin 10. Is A/C on?" is self explanitory.

The "551 Problem in Intake Manifold Runner Control (IMRC) solenoid/circuit" code refers to the secondary solenoid circuit - NOT the idle air control circuit. The cause of this code is usually that the connector is not properly attached to the solenoid valve on the rear intake plenum.

The "538 (R) System did not receive "goose" test" says you need to learn the EEC test procedure and punch the throttle when you see the CHECK ENGINE light blink during the test.

The "632 (R) E4OD - Transmission Control Switch (TCS) should be cycled once between engine ID and Goose test" says once again that you need to learn the test procedure.

The Dali Design link has a good description of the testing procedure to avoid the three codes you suspected were from your testing method. The descriptions are available at a link at the top of the main page.

Ok, one thing I have noticed is that the engine never gets warm on the gauge, but the engine gets hot to the touch. I was thinking it needed a thermostat, but maybe I am simplifying this too much. I also noticed that the cooling fan comes on, so shouldn't my gauge be reading warmer? Does this have something to do with my 116 code the ECT sensor? IF so where is this sensor located.

When I ran the test the engine was less than 50 degrees it was about 33 degrees outside.

The "336 (O,R,M) PFE sensor signal is/was was high" code indicates that either the exhaust system is plugged (check for rattling cats) or the DPFE sensor on the rear of the intake manifold requires replacement because the electrical portion has developed a problem.
This is the one on the back of intake towards drivers side with all the exhaust stuff connected to it??

The "551 Problem in Intake Manifold Runner Control (IMRC) solenoid/circuit" code refers to the secondary solenoid circuit - NOT the idle air control circuit. The cause of this code is usually that the connector is not properly attached to the solenoid valve on the rear intake plenum.

Is this the sensor in the middle of the intake that is operated by vacuum? I took it of and its dirty, but I wasn't sure what this one was. If not where is it?

I am chasing a fuel delivery problem. The car floods itself. I can only start most the time with the gas to the floor, thus shuting off the injectors. I popped the vacuum hose off the FPR and there is no gas in it, like some suggested might be suspect.

Once running it runs pretty good, but it cranks forever to start, and sometimes won't idle after starting unless you play with the gas for a few minutes.

What controls fuel delivery on startup?

Ohk the gauge problem, go to autozone and pick up a coolant temp sensor, the on for the gauge, its right near the coilpack on the T-stat housing, its only around 10 bucks that should fix the gauge problem, also the car on start up uses the other cooling sensor that is by the heater core hoses on the T-stat housing, its 25 bucks at autozone, if that sensor is bad then the car will stay in warm-up mode, and run rich(lots of fuel) Im not sure if the coolant temp sensor for the computer even pulls a code(the one im talking about is the 25 dollar one), well check those things out, and It might fix your problem.... The thing that controls the secondaries is on the back of the intake itself, it has a connector with two leads, and a two v-lines on it

UPDATE

Replaced Thermostat, And both temp sensors. Cleared codes.

Now I still get the IMRC Failure code 551.
I tried to run the Koer test..but ran out of time as I couldn't keep the car running long enough.

I did have it running long enough to cycle the coolant several times and make sure there were no leaks on the cooling system. Seemed to run beautifully. Until I shut it off and came back 10 min later to run the codes

The IMRC is the intake manifold runner control a.k.a. the secondary solenoid. Make sure the electrical connector is plugged into the secondary solenoid on the center of the backside (firewall side) of the intake plenum.

Ok...checked that..it is plugged in and the wires look to be fine. Can I take this out and test it? Or what should my next approach be?

This is the only code left, and the car still has fuel delivery issue??
