SOURCE: wont shift back from 4x4 low, to 2x2

I also have a 2002 Envoy. Shifting to and from 4wh and 4wa can be done on the fly but shifting to 4wL has to be done stoped and while in neutral. Try that. Otherwise I'm afraid its a new computer for you. Its located under the left rear seat and you need a loan for one.

You have a short to ground somewhere in the drl-fog lamp circuit. Check for obvious wiring connector or wiring to drl & fog lamps. check wiring for pinched or broken wires coming from sockets. If you don't find problem, you can trace wiring from lamps to main harnesses and hopefully find source of short.
hope this helps.

Before you spend a ton of money check the switch in the dash. Sometimes the metal just doesn't connect.

Mike fuel filter may be dirty and plugging after running tank so low or possibly fuel pump has now weakened and is failing. Have vehicle scanned o see if diagnostic codes are stored to help diagnose.

I have a 93 GMC Suburban and I got it from my dad he replaced the fuel lines and put new fuel injectors in it and it ran fine I got it today and it ran great I went to play pool and she I came out my truck...


Were the new fuel lines the same size as the originals? What about bends in the lines? Is the line kinked (closed off) anywhere? Did he use a tubing bender to make all the bends rounded?

Ask question fixya


have a pressure test done on the fuel manifold to check for pump-regulator pressure and filter performance. You state that the filter was last changed in 2007 so it is well past it's blocked up date .. Run fault codes . replace the canister . Have a compression test done as the engine is getting long in the tooth and may need refreshing .. Check that the cat converter is still operational as they will block up the exhaust system and cause poor performance

Won t start


run the fault codes and look for faulty cam/ crank position sensor as this is indicated by the backfire/hard start and lower idle RPM. Check that battery terminals are clean and tight..

2002 chevy suburban shutting off whil driving in extreme heat


I had the same problem with mine. I installed a fuel pressure gauge, and drove around until the problem started. The truck should be running between 48 to 56 lbs. of fuel pressure. Mine ran at idle at 42lbs. , not even high enough. Drove it for about 20 minutes, and it started to stumble. Fuel pressure dropped to 30lbs, 20 lbs - then all the way down to 2lbs. I shut it off, and it would not start back up. 30 seconds later, I turned the key and it came up to 10lbs. press. 10 more seconds 20lbs. After almost a minute, it came up to 42 lbs. started and I drove away. I replaced the fuel pump assemb. on 7/3/2008. Drove it around,and the problem is gone. Mine is a flex fuel, and the pump retails for $668.00. I did find a AC Delco pump for $221.00. I hope this helps.

1997 saturn sl did some errands, then wouldn't re-start


If it wouldn't start, you have to see if you are missing fuel or fire. Could be a bad sensor, or a bad fuel pump, or if the security light is blinking, a problem with the security system.

99 gmc wont start


check electric fuel pump operation ( located in the fuel tank ). Occasionally a fuel pump will burn out when running out of fuel, due to the fact the pump runs DRY for about 30 seconds till the fuel stops flowing out of the injectors, the engine quits, simultainously losing oil pressure which FINALLY shuts off the fuel pump. Sometimes TOO LATE. Hope this helps
