My car on my way to work started shutting off every time i would hit the break and my SES light would come on saying i had a code 42 any ideas what it is its a 91 3.1 i need a way to fix it since im stuck at work.

 

CODE 42 is for EST(electronic spark timing).

 

could be a problem with all the aftermarket ignition parts or the chip u have. how long has all that been on the car?

 

I have had all these parts on my car for about 5 years about. should i disconnect my MSD 6AL?

 

sorry guys but you are wrong, i got the haynes manual open to page 0_25. it says this "Engine will start in gears other than park or neutral. chapter 7 deals with adjusting neutral start switch used with automatic transmissions.

that is word for word right out of the haynes manual.
chapter 7B says this on section 5
"1 remove the screws retaining the shift indicator plate to the console.
2 slide the plate up the shifter handle and secure it to the shifter knowb with a rubberband.
3 position the shifter assmbly in the neutral notch in the detent plate.
4. loosen but do not remove the screws retaining the switch assembly.
5.rotate the swithch assembly so that the service adjustment hole on the switch is alligned with the carrier tang hole.
6. insert a 3/32 inch drillbit as a guage pin through the service adjustment hole to a depth of 19/32 inch.
7. tighten the switch assembly retaining screws
8 remove the guage pin.
9. reinstall the shift indicator plate.

this is all word for word out of the haynes manual, so if there is any problem, contact them, not me.

 

When i looked the code up on here it said EST and something aboyt the fuel pump. But dam i need to get this fixed to get home.

 

87 what the hell r u talkin about?

RS what time do u leave work? i have the haynes book at my house but i wont be home til like 4:30. hopefully someone else can get more info before then for u.

 

I leave work in 5 hours but i either need to get it working in by 1pm i hghave an hour and a half until it is 1 pm if i cant fix it its gettin towed to my friends shop

 

(almost fell off the chair laughing)

isten i looked code 42 up in the manual, on the page i specified, that is what they gave me for the cause. then i went to chapter 7 (auto trannies)where the book tells you to go, and pages specified again, and typed exactly what the book said word for word.

 

blueracer if it is what you are sayin i will be takeing it to my friends shop man this sucks it worked perfect last week with no problem.

 

CODE 42 EST (Electronic Spark Timing) The code is set when this circuit is grounded or open. A malfunctioning HEI module can cause this code.

 

87 the SES codes r in chapter 6(emission control). not the front of the book. thats the troubleshooting section for diagnosing based on a particular action. not an error code.

 

oops, your right, my fault. talk about brain fart.
i guess that i was looking for it off of memory, not taking the time to read where i was at. i just went to the front and saw troubleshooting!!!!

 

Found the problem my EST connector came off i hooked it back up SES light went away drove it around and no problems. Glad it was a cheap fix How ever the boss was mad for me beling late to work today since every 10 seconds i had to turn my car back on.

 

lol. good job. always remember, its usually the simplest thing so check those first

 

I just think its werid how it let the car run perfectly fine but the second i hit the break it would die. But hey its fixed im happy and i can go to school tonight.

 

i just fell off my chair from laughing, but yea i thought that you already checked the connections!
why is it always the stupid stuff that goes wrong(meaning easily fixed)

 

Did this code also make your car run like it was during on five cylinders instead of six? I was driving down the road when mine went to crap and it too wanted to die when the brakes were applied.
