starts then stalls

[anovib]

2002 Grand Prix GT. this is a one time incident so far.

1st try ___Starts then stalled

2nd try ___Starts then stalls

3rd try ___ cranks will not start

two hours later.. Starts as normal..

update two days later still running fine. Afraid what may be around the corner. Any ideas?

when it stalls do any lights come on? "Trac Off" by chance? This indicationg a failing crank position sensor.

You could also try unplugging the MAF sensor to see if it will start with it unplugged.

I agree with Tim, your symptoms are indicative of either a bad CKPS or MAF sensor.

I've had this happen a couple of times recently...so far has gotten started each time. This seems to happen at a gas station fill-up (??).

Anyway, what I've been doing is to key up to the 2nd position to allow the fuel pump to run a little bit then it seems to hit on the 2nd try.

I do have plans to replace the crank sensor at my next planned maintenance session.

crazyhorst, your issue almost seems like a fuel delivery problem.

[CrazyHorst]

It may very well be...my bro had the fuel pump replaced under duress about 120k but not with a GM-Delco part....it is on the list...I was planning to wait about 2 years before I dug into it again unless forced sooner......

[tblake]

on the list.....

(seems to get longer and longer doesn't it?) Same for me, there are a bunch of things on my list. Just not enough time.

How has your car been since the most recent service?

[CrazyHorst]

The car has been running well as far as I can tell. The running average mileage on the DIC was topped out at 25.2mpg max before the service, I saw 26.6mpg on Friday. Not that this is the absolute source of truth on mpg, but at least an apples-to-apples comparison.

My one major driveability issue was the 4th gear TCC locked, ~45mph under 2-3 bars of boost, usually "lugging" uphill where it would stumble badly. This is completely gone.

In other interesting technical news I learned that the GTP has likely never seen a drop of premium fuel other than what GM put in it at the assembly plant. Conversations with my brother indicated he never put anything other than 87 octane pump-regular in it and neither have I. So maybe I'll be a cautionary tale. Maybe not...its mostly been a commuter car with a slight bit of rock-n-roll mixed in.

Regarding list of projects...you see I have 4 hi-milers...current limitation is to get a personal shop facility going in my new location. Hopefully planned for this summer.

CPS have something to do with it, is engine light on?
