  • no start after overheat

    96 contour sport 4cyl 5spd mileage unknown, had been overheating for 2 days, it got hot and died while stopped at offramp. wouldnt restart. pushed to parking lot, let cool for an hour in 35 degree weather,filled up reservoir with water. started right up drove a mile home. next day got in no start. have spark, timing correct, good even compession all cylinders,tried starting fluid no start.pending code for temp sensor,oil level went up, getting something in it, doesnt "appear" to be water, not milky any ideas? searched forums saw nothing quite like this.

    after overheating the engine several times .... I would get the cylinders' compression tested

    I would also check out the fuel system, as running lean will cause overheating and difficulty in starting ....G

      I will compression test cylinders again. Shouldn't it have started up when i used the starting fluid? that baffles me.

        ... until you prove you have the basics.... trying to second guess the issue can be confusing.

        Prove you have compression
        establish you have a spark at each plug.and fuel pressure at the rail.

        Turn the engine over to see if the plugs get wet ... all of them.

        post up the figures so the guys can see them .... G.

            If you overheated deep enough then engine damage.

            If the oil level truly went up then water in oil, the oil only gets milky when they mix, under odd circumstances the water can simply sink to the bottom of pan and not show. Maybe you should drain a bit of the oil to check.

            Need at least 120 psi each cylinder to run correctly.

            Many have trouble with starting fluid on MPFI cars with 'dry' intakes, the volume is quite a bit more than on old school carbed engines and the amount of starting fluid has to be increased but that leads to another danger, the possibility of a misfire then having enough fuel to shrapnelize (is that a word? never mind I just made it one) the intake into a million pieces to then kill somebody with a backfire that lights off the ether in the intake. Meaning if spraying the normal 2 second max shot for safety the engine will likely not start, not enough fuel.

              Has water in the oil, taking head off currently, will post with results after that. I really like this car, hope a used or rebuilt head is all it needs. Thanks for the replies!
