[darush01]

I have a problem with my 2000 jimmy i thought it was fuel related but ive had 2 shops say its ignition one said it was the ognition switch i had them replace it and it did nothing, now another guy says its the ignition switch module but wants almost $300 to fix it, where is the module and how hard is it to change? If i can do it and save as much as possible id like to because im on a tight budget any help appreciated

OUCH! The part only costs a few bucks. It's located above the left side valve cover. It's bolted to the coil. Disconnect the distributor wire and harness. Unbolt the bracket hold coil and ignition module. Seperate them, and replace the module. 20 minute job!!

You can see the coil in this picture left of the TB.

That is the ignition control module right? I finally got to talk to the guy who wants to charge me 300 for a 20 min job and he sounded sure that that was my problem so im gonna try it thanks for the info

I'm coming from a different angle on this one-are you getting good oil pressure while cranking? If the ECM does not see enough oil pressure while cranking, it will not kick the fuel pump relay on or fire the drivers for the injectors. If the ign module doesn't change anything, try changing the oil pressure switch/sensor and/or inspect the wiring for it.

If it doesnt fix it ill look at that thanks for the idea

Did the mechanic mention it does not have spark? If so then, yes the ignition module has failed.
Quick test. Pour a little fuel down the TB. Crank it. If it runs for a few seconds, spark is good, fuel delivery is bad.

i recommend checking out s10forums for problems with your model and year. I have a 2000 gmc jimmy 2dr 2wd 5 speed and let's just say that these vehicles have some pretty common problems. Almost all of my searches end up in those forums reading problem descriptions exactly like those i was about to write. Like said above, spray some fuel down and see if it ignites to test if ignition is working or not.

So, what is the problems that you are having with it? Does it start and run? What are the issues. Then I may be able to give you a little help on figuring the issue out.
