Engine trys to start but stops. Could the SRS be involved & how do I fix it?

and the dash controls. I have bench tested the old mode actuator and it works in both directions. I have tried to calibrate several times. Could the dash controls still be bad.

2005 Silverado z71 automatic ext cab 4x4 5.3L V8

I have had it checked by my son with a plug in under the left side of the dash. He says it is the e-vac system and that I could have a leak or a censer if faulty. Can you tell me a common fix to this or give me a little info so when I take it to a mechanic to have it checked and won't get my bank account raped.

I tried turn on AC but looks like it won't turn on. Light on switch keeps flashing

I was in 4 wheel drive high now I'm trying to get it back into two wheel drive I've done it several times and it will not work what do I do

I need help determining where to start with diagnosis. There are no engine codes. The maf and iat seem out of wack. See 20 data points and description below:

MPG has been 12 in mixed driving for a while but this is the first time data points were pulled.

When I shift to reverse or drive and push accelerator there is a slight noise from rear end. Guessing u joints are bad. Do I need to replace all? Is it expenpsive? How difficult to do on my own

Had charging system tested battery tested "good" 12.59V 930CCA rated 770CCA temp was 65 degrees though. What about below zero temps an wind chill? Starter tested 11.22V 217.2Amps Charging test No load 14.74V Loaded 14.65V I would rather not replace battery if not needed

Just had a rebuilt tyranny installed.

Recently had rear rotors replaced and now I'm receiving a brake system error every time I drive at random times. ABS light comes on too. Technician looked at it again and couldn't find anything wrong. Now wants to charge me to investigate further. I'm calling BS because it never happened until they worked on the brakes. Any ideas?

after a few seconds sometimes the problem will clear & it runs ok again. sometimes you may have to cut ignition off to stop problem and it may or may not restart without a jump start & it runs ok until next time. has been to dealership, no trouble codes show up, no prolems found. HELP!

flash on & off,gauges jump up & down,engine starts bucking like its being turned on & off. after a few seconds all this goes away and its ok until it happens again. dealer has checked it,no codes show up, no problems found.help!

My truck functioned perfect all day and I parked it for the night. I tried to start it the next morning and nothing happened. There was no starter click or noise of any kind when I turned the key but the cluster lights and bells. The lights and bells stopped functioning instantly also and all that remained on was a battery light. I turned the key probably three times and nothing. When I looked down to remove the key and pursue the problem I noticed a very small wisp of smoke coming from what looked like the top of the steering column shroud where it disappears under the dash on the ignition side. It didn't smell and lasted a millisecond. I checked the battery connections and battery they were good. I checked the starter and when the s terminal was hit with 12v it worked properly. I checked all the fuses inside the cab and they were all good. I found the ign b 40amp fuse blown in the engine compartment. I put another fuse in and the results were the same instantly blowing the fuse. I have concluded with the small amount of smoke I saw and fuses blowing there is a short and it's probably the ignition switch. Before I start tearing into the steering column I thought I would ask first if there is any other possibility it could be?

lights flicker, abs light comes on i changes battery, cleaned terminals, alternator been tested it good

Was driving down the road heard a pop and the truck acted like it ran out of gas checked the fuel pump fuse it's ok was gonna check to see if the emergency fuel shut off switch went out

I want to know what it could be.
How much will it cost?
and where do I go to fix it.
