Has your Jimmy had any hot day starting problems since replacing the pickup coil? Now that it is summer my Jimmy symptoms sound a lot like yours. let me know, it has been a 3 year mystery for me...lucky Cannada has only 2 months of hot weather.

Sending unit on engine or the wire to it would be first place to look and easy to change.

i have a 98 jimmy with a 4.3 csefi and it wont start unless I put gas down the air plenum. I have checked all the engine sensors and fuel pressure, had to change crank sensor was bad. what I dont understand is why after I dump fuel down it it will run all day drive it anywhere as long as you dont shut it off and let it sit for more than 30 to 60 sec. if you do it wont start again unless you put fuel or eyther to it. please help its driving me crazy.

Was the fuel pressure a minimum of 60psi with key on engine off tested at the fuel rail test port? There are several articles published on this and that is required to fuel the richer start mode. Running drops to 54psi. Fuel filter been changed also. After this - you also take the air housing off to do this so is the air filter clogged at all. Try unplugging the MAF sensor on startup and see if it starts - clean it with electronic spray or replace if this fixes (larger connector in air housing to the 1" wide metal asssembly).

This is a 98 you said so no MAP - yes thats the MAF there. The small one in the air housing is a temp sensor. Again, 60psi key on engine off for start.

We need your help! by tidester HOST

Hi, everyone. As you've probably noticed, we have been trying to refine the discussions into more narrowly focussed topics. Our objective is twofold. We want to make it easier for people seeking specific information about their vehicles to find it easily and without having to wade through hundreds or thousands of postings.
 
To those ends, we will be shutting down the general make/model discussions and work exclusively with specific issues. This requires us to populate the make/model subsections with relevant, interesting and timely topics. Rather than having the hosts simply create boilerplate topics for each make/model, we feel that you, the owner, the make/model enthusiast and the prospective buyer can best judge what those topics should be.
 
You can help by adding a discussion (it's easy!) or suggesting one here.
 
To add a discussion, click on the last link in the "You are here" line at the top of this page. That will take you to the topic page for this make/model. Review the list of topics and click on the "Add discussion" link when you've decided what topic you'd like to add. Follow the directions and you're done! Feel free to add more than one. Just avoid duplicating existing topics and try not to make it TOO specific!
 
Your help and continued participation in the Forums is greatly appreciated! Thanks.

I own a 2001 gmc jimmy diamond edition,I have a problem with the hvac switch,it usually stuck in the vent position and very rarely does it go to any other position.I have read a recall that a vacum switch is leaking oil and it is getting into the hvac switch.Where would I find this vacum switch.
