#289 of 301 Jimmy [jsimmes] TEMP SENSOR switch
Aug 08, 2012 (5:45 am)
Jimmy, There is a engine temperature sensor switch on the engine block between the #1 and #2 spark plug (driver side). Two wires, remove the wires and if vehicle starts everytime replace sensor $25 to $35. Do not leave wires pulled off, if you do it will waste a lot of gas. Depending on temperature of engine this sensor send a signal to computer and computer send gas to the intake. Hope this helps.

#293 of 301 99 Jimmy vapor lock when it is hot outside.
Sep 24, 2012 (10:21 am)
When it is hot outside, I have to drive with the gas cap off. Recent;y with cap off I am vapor locking. This is new.
When it is hot if i leave the gas cap on the car will vapor lock and a whoosh of air comes out of the gas tank when I open the cap. Gas is also pushed out of the purge valve. I have tried a vented cap same problem.
I can drive the when it is below 75 degree outside with the gas cap on. Gas mileage is perfect, no pressure when I remove the cap.
Parts replaced: sparks, rotor + button, wires, all O2 sensors, new fuel tank, pump, fuel lines, fuel filter, evap charcoal canister, evap purge cylinder, and the evap part by the carburetor.
In the past it has given a p1352 code with the vapor lock condition.
#294 of 301 1993 GMC Jimmy start and stall problems
Sep 26, 2012 (9:33 pm)
Hi,I have a 1993 GMC Jimmy that will start and run for a few.maybe 5 minutes at idle but after a few minutes if you hit the gas it will stall out and will not start back up...If you wait say 1/2 hour to an hour it will start back up but stall again in a few minutes...So far i have replaced the gas tank...The gas pump...The gas filter...The gas pressure regulator and the fuel pump relay but it still does the same thing...Any ideas on what else i could try to get this thing running the way it used to run would be greatly appreciated...Only thing i havent tried is maybe loosening the gas cap...I just thought about that...I'm running out of ideas here...Thank you and have a great day...
#295 of 301 98 GMC Jimmy won't start after head gasket replacement
Dec 14, 2012 (9:18 pm)
I have a 98 GMC Jimmy with a 4.3L V-6. My son was driving it and it died on him while driving. Low and behold, there was water in the oil. It sat in the driveway for about 3 months. I finally got around to getting it in the garage, and replaced the head gaskets. I got it all back together, and it won't start. I've replaced the following items: plugs, wires, Distributor cap, rotor, Crank position sensor, cam position sensor, fuel pump. I have tested the ignition coil, ignition control module, and all fuses. And, oh by the way, I had to rebuild the starter as well. I did get it to start one time, with the gas pedal on the floor, but once it fired up, I let off of the gas, and it died. It hasn't started since, or even acted like it wanted to. I'm at a loss, with the exception of a possible timing chain slip. I really don't want to go there. I have poured a little gas into the throttle body, yet still nothing. When I crank the engine, I do hear a little bit of a "flutter" from the exhaust pipe. I'm at a loss. I do have a 5 gallon can of gas, and a match. Any thoughts?

Did you get the problem solved?
I have the exact same issue now with wife's 2000 Jimmy. She over heated it , water in oil, barely runs now. Now I'm persuing head gaskets, BUT....
If you're gonna replace the head gaskets....you have to send the heads out for warpage & to be pressure tested for internal CRACKS!!
