93 Grand Cherokee-Won't Start in Cold
 

Hi all.
Hope to find some suggestions here.
93 Grand Cherokee Laredo, 6 cyl, auto, 4wd, air etc. Has 220,000+ miles, been excellent and still is.
Problem is when the temp gets into the 30's, it will crank and crank, give a huff or two like it's trying to start, but no go. New plugs, wires, Oxy sensor, other things over the last couple years.
Read a forum message somewhere on a similar problem and the fellow said he finally took off the ECM and heated it in the oven. Seemed it had a crack in the insulating material that let moisture get in and freeze. Or something like that.
Possible related symptom; the engine, when running well, gives a 'miss' on acceleration at right around 2800 rpm and has for years. I've gone through most everything but am really suspect of the MAP sensor or the ECM now.
I've had a lamp on under the hood for overnight, but no help to start today. I would appreciate any ideas or suggestions for this old beauty.
Thank you.

Re: 93 Grand Cherokee-Won't Start in Cold
 

Update to this problem.
I got a can of starter fluid and tried it. The car seemed much more willing to start, but still no joy. It did huff a lot more, but didn't actually start. In my view, this points to more of a fuel problem than electrical? If there's concurrence on that, what in the fuel control system would be so subject to the cold temperature?
Would appreciate additional thoughts. Thanks.

use starter fluid for anything.

I know, I know. At my wit's end. Only used a short shot though. Figure the
valves are prob. loose enough, a little more wouldn't hurt catastrophically.

Re: 93 Grand Cherokee-Won't Start in Cold
 

Do you have a ballast resistor like in the Cherokee?

When those go bad, the engine will almost start with the key turning the
starter, but drop to run and it up and dies.

Re: 93 Grand Cherokee-Won't Start in Cold
 

Thanks Mike. I think it does have a ballast, but again, it never gets close
to turning on it's own enough to let up on the key.
Also, I don't think the ballast resister would be affected by the cold like
this.

Re: 93 Grand Cherokee-Won't Start in Cold
 

Thanks Mike. I think it does have a ballast, but again, it never gets close
to turning on it's own enough to let up on the key.
Also, I don't think the ballast resister would be affected by the cold like
this.

Re: 93 Grand Cherokee-Won't Start in Cold
 

AH. I remember in college (Potsdam, NY) it was below zero (+/- a few
degrees) and my buddy was outside trying to start his car. He poured some
gas into the carb and it still wouldn't start so he came in to take a
shower. I look out my window (I had a great view of the parking lot and the
grass where the chicks would tan) and I see this car on fire. I trotted
down to the bathroom and was like "dude, your cars on fire"... well, thank
GOD he grabbed his towel before sprinting down the hall to my room!!

Car burt to the ground (there is not a more miserable sight than to watch
firemen put hoses away in sub-zero weather).

I lost some eyebrows in the service that-a-way. Believe me, I'm careful.

Re: 93 Grand Cherokee-Won't Start in Cold
 

I'd try to fix the problem as to why it's not starting. Mostly
because I had an old Austin Healy with the side draft carburetors that
one of the slide was stuck open, that sucker went to twelve grand and
exploded so quick. The only place I'd use it is if gasoline was puddled
in the intake manifold, from severe flooding, fouling the spark plugs.

Re: 93 Grand Cherokee-Won't Start in Cold
 

Sure it would, especially if the starter bypass wasn't making a
connection. What happens when you battery jump it, spinning the engine
twice as fast with a hotter spark.

If the starter spins fast enough and you get no firing, is either
fuel or spark. Unless it stops right away in which case wrong
oil weight is another suspect.

You mention a miss even when warm... that would be worth getting
rid of as that engine should never do that.

Still the same problem, just spins a bit faster.
Location of the ballast resister? I'll put the torch to it. j/k. I will try
a lamp though.
