SHO won't go!!

[Trojan Man]

Hey all,
I have a problem. The car is getting spark and it is getting fuel, yet it will NOT start. I pulled the plugs, cleaned them, etc, tried everything that you would normally try to get it to start, but nothing. Any ideas what could be wrong?

Have you done a 60k service? Your crank position sensor could be out. Thatd do it. Its usually caused by the water pump leaking all over the cps.

Is there any sort of popping when your trying to start it, and do the RPM's jump up quickly while cranking with no accel and WOT?

Check for codes?

Need more info. What services or problems preceeded the no start condition?

The engine has 101k with no 60k done. I was under the impression that I would not get a spark if the CPS has failed. The waterpump isn't leaking.

As far as popping, the engine did fire for a split second 2 times, but that was it. And it was only for a fraction of a second. Other than that it just cranks.

I haven't checked codes yet. Maybe tomorrow if I have the time.

The car has been running fine lately. It has been a little hard to start on a few occasions but I just blamed it on the cold weather. The only thing I did before it stopped running was pulled the battery. The only thing I can think of is that perhaps something got fried somehow when doing this. (I took the battery out to get the headlight out so I could polish them, at least they are nice and clear now.. lol)

Thanks for the help

How did you confirm that the engine is getting spark and fuel to the cylinders? Hard starting is not normal even in cold conditions for a sequential port fuel injected engine such as the SHO's. Something is less than optimal for the engine to run. We can only go on the information that you provide us.

I used a spark tester and the spark plug to test the spark. It's a good clean spark. For the fuel, I can smell it, see it on the plugs, and hear the pump.

Any more ideas?

Well how's this for a weird one... I go out into the garage this morning to try pulling codes, and the damn thing started right up!

It seems to me as though the timing is out of whack or something. It would hardly fire last night and this morning it just started right up and ran smooth as ever. Is there something that could pose an intermittant problem causing the plugs to fire at the wrong time in relation to the opening and closing of the valves?

I'm still going to check for codes and I'll also check the tension on the timing belt.

Any more ideas?

Thanks everyone,

Well I pulled the codes but it doesn't seem to make sense. I did the KOEO test, and got 33133. It gave 3, then 3, then 1, then a long pause, then 3, then 3 again, and that was it. Doesn't seem to make much sense to me. This is a 92 so it should have a 3 digit code. I checked Shotimes and 331 isn't a code.

Engine still runs though. It seems to me like perhaps when I first went to turn it over yesturday, it may of not been sparking, which flooded it. Then after the sparking started to work again, it wouldn't start because it was flooded. But after sitting over the night, it fired up this morning. So it seems to me either I have an intermittant spark problem, or a timing issue.

Thanks

Sounds like the crank sensor might be failing. Or the cam sensor isn't finding the correct firing order? The code you have read is incorrect unless you have egr problems.

If it were the CPS I wouldn't be getting a spark though. I'm not sure about the cam sensor.

I did drive the car around tonight with no problems.

I'm stumped.

Im not sure if a bad cps=no spark...

Well she did it AGAIN today. Came out of work, hop in the car, wouldn't start. I'm gonna go back again in a few hours and see if I can just get her home.

BTW, the tach does move while cranking her over so it can't be the CPS. All I can think of is the computer...
