I posted several months ago about this starting problem. Car
run for more than a minute or so, it would stall and then not start until it
sit overnight. I have since changed the fuel filter and that seems to have
somewhat. Now the car starts and will run until I shut it off, but (I think
what is going on) if the car sits in the super hot sun and cooks for awhile
start for a few seconds or will not start at all. When I try to start it
when the temp
cools it always starts. So is there something that the sun is getting hot
that is not
allowing the car to start. I'd really like to get this car back on the road
but it is not worth taking to a mechanic. Thanks for any info,
Before you piss away all that money!
Try disconnecting the Coolant Temperature Sensor, if it is on the low side,
it will send a cold signal to the computer. Flooding the car and making it
stall after a few seconds, if it starts at all.
The 2.2 has a new type of injector on it, where the dwell time is almost
like an on and off, rather than a timed injector.
My money is on the Coolant Temperature Sensor. I'm not ruling out the
Module, or the crank position sensor. Which, by the way are a major pain in
the balls to replace on a Cavalier. But I own a cavalier with a 2.2, and
have fixed literally a hundred of them. It qualifies me to make the sensor
statement. not that the others are inexperienced. But the other poster even
said he had a 3.1.
It should be:
On or near the thermostat housing, I'm nowhere near mine. So I can't look to
tell you. There is a two wire connector on the sensor, and I think one wire
is yellow, with a red tracer?
Thanks Refinish King, I found my Haynes book to look it up. It looks like
there is actually 2 sensors, one with 2 wires
and one with 1 wire. The thing ran fine today, ran it for 10 to 15 minutes,
hiccuped a few times. We will see what it does
on a scorching hot day. I'll post back when I find out something.
It will hiccup if you run the car with the sensor disconnected all the time!
Disconnect the sensor, let the car run for five minutes or so, then you'll
have an idea if that's the problem, shut it down, reattach the wire. If the
car doesn't restart, you know for sure you've found your problem!
The one wire sensor, is more than likely a temp gauge or idiot light sensor,
depending on which your car is equipped with.
Sorry to hear that:
I hope you don't junk the car for a $40.00 starter?
If so, where are you located, I'll buy it for what the salvage yard offers
you if you aren't too far. As long as it's a two door?
I usually put V-8's in them and make them rear wheel drive, I just gave the
third one I did to the customer, so he could finish it himself.
