Codes...no start

[ATXSHO]

Well here's the codes:

"KOEO"

96 = High speed fuel pump circuit open
14 = PIP circuit failure
79 = A/C or defrost on during test (my air doesn't work)
32 = EPT cicuit voltage low (PFE)

My car never had the CE light until last night on the way home. Before that, my car would start up and then all the sudden it doesn't start and I changed the starter soleniod & clutch switch and it didn't help. My car doesn't even crank, just goes in the on position and nothing else, no clicks no nothing when trying to start. I been driving my car by bridging the starter solenoid and then from there, started seeing the CE light.

Anyone out there that can point me out what the heck is going on or what it is? I need to know as this is about to be equipped with nitrous.

Thanks in advance.

Oh yea, it's just so weird how all these codes pop up in a half an hour drive. jpshakeh

I had did the test over and the same codes are still there accept for code 32, which vanished in the KOEO test.

"KOER"

91 = HEGO sensor indicates system lean (front HEGO)

Fix the starter problem first, then worry about the codes.

You say you replaced the clutch switch on a 93 ATX??????

First, clarify what you really meant by this.

I had some similar starter issues when the battery cables where corroded. I would check all the connections, and clean them up a bit.

Starter problem? Yes, clutch switch and two digit codes from an 89. thumb Whatever it is, is causing it not to start from what I seen. I have this big ol' book and it says for those that can't start their car go to the next part and asked if it cranked and mine didn't and then it referred me to another book. shrug Never saw that and for my other codes, the book didn't personally list it, it simply said for all other codes go here. I'm really confused.

The battery cable connections are fine, as I checked and the fact that the car can still start when I bridge the solenoid.

Can I also mention that what ever it is,it's droping my track time dramatically by at least a whole second everytime. frown

Your signature says "93 ATX" and thats really disconcerting. You should probably change it so that you dont have to say you have an MTX in every post.

Well my non-reading self misread the codes , so here are the new *correct* ones.

"KOEO"

49...67...91

Fix the flippin' starer circuit. The only thing there is the ignition switch and the clutch interlock switch. The clutch has TWO switches, only one is for the starter, the other is for the cruise/PCM. Get your meter out and start diagnosing it properly instead of guessing.

Then, reset the flippin codes.

Start over. You're getting yourself (and us) screwed up by not following a logical process and not giving complete enough information.

Then where's the other switch? And how am I guessing and not giving enough info? I stated what was new and what codes and problems I have. I cleared the codes and only have 67 and 91.

67 = neutral/drive switch open or A/C on
91 = No HEGO switching detected

So from what your saying this other switch is bound to be the one described in code 67? As code 91 in memory only says that stated above and in my KOER it says the rear runs lean. Do you also think as I'm thinking it's the back 02 sensor?

"Not enought info" - failed to identify specific vehicle has nickname and signiture that indicate a different vehicle.

"Guessing" - swapping parts without troubleshooting.

The second clutch switch is located on the upper end of the clutch pedal arm and has W/PK & R/LB (89 colors). The lower, easy to get to swith with the P/Y & BLK/W wires is for the cruise/PCM.

See this post: http://www.shoforum.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=20;t=001168#000001 for exact steps to take to properly diagnose the primary starter circuit.

As for the 67 code, make sure that the climate control is set to OFF. Make sure you are not holding the clutch in while running the test. Make sure you distinguish WHEN a code is issued so that you can determine if it is a KOEO, KEOR, or Continuous/Memory code. Certain codes must be read in the context in which the computer issued them in order to be properly interpreted.

Make certain you follow the Quick Test preparation instructions by properly warming up the O2 sensors prior to performing the KEOR portion of the test. If the sensors are not properly warmed, they will give inaccurate test results.

If, after making certain that all prerequisites are met and the results are repeatable, then you can assume with a high level of confidence that the results are accurate and that the sensor is likely the fault.
