95 found on road dead

[mcquack]

Alright, here is the deal. Any advice would be greatly appreciated. My 95 seems to have a mind of its own. It will run for a while with no problems, not even a CEL then out of nowhere completely die. Sometimes I can drive it for 1/2 hour with no problems, sometimes only 5 minutes. It seems to have the most problems stalling when coming to a stop or decelleration, however, not limited to this. Once the vehicle dies it will just crank with no attempt to start. However, if I wait ten minutes it will start up like nothing ever happened. I noticed this did not begin until I become dangerously low on gas, unsure if this could have been a factor or not. I have had a mechanic replace the ignition module, thinking that's what it was. He says that he does not believe it is a fuel problem as he still has fuel pressure while the vehicle will not run. Yet the problem still continues and my mechanic has kind of thrown up his hands. Thanks in advance for your help!!

Uh, sounds like a cranksaft position sensor

Ditto, look in my sig for a link to check the codes yourself for free to confirm this.

My 93 did this for about 2 weeks before the fuel pump relay died. It also seemed to have fuel pressure, ran fine when it would run, finaly she quit on the way to work and would not restart. After it sat for a couple of hours it started and ran just long enough to get on my trailer, but that was it. I wired a jumper around the relay and put power to the fuel pump and she started and ran great.

Went to pick the car up from the garage tonight to begin to do something )with it. Made it about half way home (6 miles ) when it quit. Went back tonight to try to get it and it still would not start. This time the motor turns over about 10 revolutions then runs for less than a second before starting to crank via the starter again. It continues in this same rhythm and will not start. Hoping this gives someone a bit more knowledge as far as what is wrong. I was going to attempt bypassing the fuel pump relay but could not find it. Any help there would be appreciated as well.

I would say fuel pump or fuel pump relay

please pull your codes,before you go throw money at it!
my GUESS is a crank position sensor,but it could be somthing else too
check you codes ad let us know what you get

Pull The Codes

 

[mcquack]

Alright, went tonight and got the codes. Hope they mean something to someone. The only codes I could get were KOEO. They are as follows:

172,175,176,211,332,335,543,648

Focus on the 211 code.

Click on the SEARCH tool and enter 211 as your search argument.

Once you fix the cause of the 211, reset the computer and see if the O2, EGR, and tranny codes come back.

Thanks for your help. After doing some searching I am quite sure the problem is in the CPS. I had the water pump replaced approximately 2 months ago because it was leaking something fierce. The car currently has over 180K and I doubt a 60K was ever done. Currently leaking about a quart of oil ever 120 miles from valve covers, plug seals, etc. Therefore my next question is if there is on the board within a reasonable distance from Jackson/Lansing Michigan area who would be willing to work on this at a fair rate.

172 No HEGO switching seen. Indicates lean.
175 No HEGO switching. System at adaptive limit.
176 HEGO shows system always lean
211 PIP circuit fault
332 Insufficient EGR Flow
335 PFE or DPFE sensor voltage out of range
543 Fuel pump secondary circuit failure. Battery to ECU
648 Incorrect gear ratio for 4th gear

My money is on CPS.

My SHO was doing exactly the same thing. After many tows to the shop it turned out to be the CPS.

 

[mcquack]

All fixed

Thanks guys for all your help. Replaced the CPS last week and all is working great. Now if I can only find someone close to do a 60K

Scroll down and check the Great Lakes SHO Society forum. We're in the planning stages of a tech meet in the Grand Rapids area

I have had this same problem....and I used to deliver pizza my car is at mechanics right now maybe it is the CPS
