Don't think so...

The one that was on my 76 saab...

As to the Toyota, we've got an 87 with 192k on it. Only really started having to make repairs around 175k, so I'd say its a pretty good truck. Aren't S10's import? No offense, but I thought all those little trucks were made in Asia regardless of brand name. Maybe I'm a decade or even two behind the times.

>I just went out, cracked it for a minute and it started. }:~[

It's got to be something simple, and that is why I hate to spend big money on a replacement truck. Besides, I'm of the mind that everything has a fix. If the motor was wore out, body was rusted out, front end was bad, transmission slipping,etc, etc, than I'd have no second thoughts of getting rid of it, but everything is in good working order--just won't start when it's cold.

Jesper, I hear ya'.

Joe, I changed the coolant temp sensor just last year.

John, No offense taken. I admit that I don't know where the S-10 is made either, so it just might be an import for all I know.

>I thought the S10's were Izusu's. I have my second one. I'm not 100%, but I don't think there is a cold start injector on a throttle body. Could be wrong though. One common problem on those throttle bodies are the IAC valve (idle air control). This is a simple little valve that controls some air flow during idle. Being intermittent and only when it's cold, it could be a contact issue (connector or ground somewhere). Might check when it won't crank to see if you have fire and fuel. I would buy a book at the zone. I'm not a big fan of the S10's but they will run forever. My old one is still going at close to 200k miles. As for buying American, its darn hard to do these days. Our old Chrysler had a Mitsubishi engine, the S10 is an Isuzu, lots of Japanese companies have plants here, etc. Anyway, good luck with the truck. Those engines/systems are fairly simple, so hopefully, it won't be too hard to figure out. I went through all the simple stuff on last one once and it turned out to be the computer. The dealer mechanic figured it out by accident (long story).

>I brought in my Haynes book to work with me to look thru, and have discovered that there are at least 3 different throttle bodies I could have. Tomorrow I'll have to check to see if mine has a tag on it saying which model it is. Right now the truck is at home doing it's "plant-pot" imitation.

Thanks for all the info.

Lower 60's and it's cold out OOOOHH

>Dang Todd I hope you werent serious about moving back to Maine! I here it gets even colder there. 60� and I am still wearing shorts and flipflops to work. They sure do make them soft down there in Florida.

Get the Totota...

>I bought mine new in 1992. 150+K miles on it, I just had to replace the water pump, radiator and clutch. Still on the orignal brakes. Great trucks and as Jesper said they made a bit north of me in Fremont CA.

DOH! Make that Toyota...

>Now Ernie, you know much better than that! It's not that I think it's cold, it's just that warm blooded S-10 of mine. I orginally bought it in Maryland and am thinking of sending it back!

Yeah, right, like 60 above is cold, HA! Now I might find 60 below be a bit brisk I will confess, but only if the wind is blowing. 60 above Heck man, that's easily t-shirt weather for me.

>Hey Todd,

I don't know anything about the 4.3L Vortec Chevrolet motor, but on the thought of you getting a Toyota and thinking it un-American, you must remember that although parts are from all over(mostly Japan), I know for a fact that Toyota has at least one plant in Indiana making the Tundra. I would almost guarantee they have plants for the Tacoma as well. I am ABSOLUTELY NOT a Chevrolet man, but they are trying to regain some of the market by providing a decent warranty (5 years 100,000 miles)to bolster their sub-par products. So, if you have been happy with the S-10, and other GM products, I would at least consider. If the Japanese hadn't brought their cars over to North America, we'd still be driving cars that drank gas, weren't efficient, and needed new piston rings after 70,000 miles. I can't help but be drawn to the foreign offerings. They raised the quality bar. Now 'foreign cars' are foreign designed but American built. I can't argue with that.

Andrew

Good Idea!

New PLant Here

Tony - Memphis


>A subsidiary of Toyota just opened a plant across the river from here to make truck parts. I forget which truck, but there is talk of opening a truck plant in the same area someday. Nissan has a big place over in middle TN and there is a big Nissan plant in Al not far from here too. The lines are blurred these days. Our new Nissan, however, came over on a boat.

Re: S 10's are 'Murican

Tony - Memphis


>Actually, the LUV was before my time! Chevy and Isuzu did do a joint thing on the S10's, but they were made here and Canada. This is straight from a GM brake engineer (who drives an S10 too)...Both of my trucks have had the 4.3L. About the least efficient motor one could imagine, but they do run forever and with very little maintenance. I've even gone to the extended synthetic oil and once a year oil changes. Funny thing is, our Nissan manual specifically says to use conventional motor oil. Not sure why.

They actually made some Isuzu badged S-10 pickups like you and I have. And some Isuzu Trailblazers as well. We see them down at the truck plant south of us here frequently. But no � they are good �ole American designed and made vehicles.

You may be confusing your older truck with the new Colorado/Canyon line. They were indeed designed by Isuzu, but made in North America. In our parlance, they are called GMT-355s. The Isuzu branded version, made in Korea and sold in the Far East is referred to as an I-190. From a brakes standpoint, there are subtle differences � like a 14� (small) system over there. But that�s all I know about � the brakes.

Isuzu did flounder at the end, as start of production neared, and GM Truck North America had to step in and save the day. I think they learned they can�t trust such an important part of their product offerings to such a minor player. As far as I�m concerned, they still have a hole in their portfolio � no small truck like ours.

>Todd, temperatures in the lower 60's were just about where you used to have a carburator freeze - in the old dys of Holley double pumpers. You could try something simple like finding out if there is some condensated water in the tank - it does not take much.

If the tank has a drain plug, let some out when the tank is low and see if there is any water in it. Add some methanol to the tank as a co-solvent to get the water and gas to mix, or make sure you tank up with gasohol for a couple of tankfuls.

It is cheap and if not the problem, you haven't lost much.

>My local library carries the various car repair manuals (Motor, Chilton, etc.), and even a few of the vehicle-specific manuals. If you haven't solved the problem yet, I'd go to your library and see what they have.

I'm not current on the American fuel injection, but cold start injectors are somewhat old-fashioned devices - the newer fuel injection (and early 90's should qualify as "newer") don't have a separate injector, but simply crank up the rate on the regular injectors when the system senses cold ambient air and cold coolant.

Your truck is of the era that it might have an OBDI system, in which case, you should read up on the codes for fuel injection system, and see if the system has popped up any codes that will help you.

Old-guy grumble - it ain't like the old carburetors, where you could spray in some spray-start, hold the choke closed, and see if it started. On the other hand, both fuel economy and exhaust pollution are so much better with these more sophisticated systems that it's, in my opinion, a worthwhile tradeoff; maybe eventually, I'll start to get the kind of intuitive feel for what the problem is that I developed years back with carburetors and points-based ignition.
