2010 GMC Sierra 1500 - Page 8 - Answered Questions & Fixed issues

It's the gas cap sensor. Or you are getting a vaccuum leak somewhere.

1996 GMC 1500 Pickup.
Replaced Coil, Dist cap/Rotor, Ign Mod & pick-up.
All showed to be bad with OHM meter.

20A ECM-B fuse keeps blowing out and I'm afraid to burn these new parts up....

ANY IDEAS OUT THERE???

hi, 1- the sensor can look the same from outside but maybe not having the same specs 2- deffected wheel 3- bad fixing/bad wiring plug fixing

Put more than 3 gallons of gas in your tank- $20 = 3.5 gallons here. The bottle of cleaner specifies how many gallons of fuel is to be mixed with the cleaner. Usually 8-10 gallons for the small bottle cleaners. Whatever. Follow the directions. It will likely run like garbage for about a quarter tanks worth, but should clear up eventually, UNLESS - there was something wrong before you put the cleaner in. Have you put cleaner in before now? If not, why did you decide to do it now? If there was an issue before, that issue needs to be cleared up before trying additives, unless you are absolutey sure you have a dirty injector or two. Also might help to buy the highest octane rated gas you can for a tank or two. The more expensive brands (Shell, Exxon, Mobil, etc.) usually have some detergents in their gasolines that help clean injectors on their own too.

check shift cable for adjustment or wear

Model 3210 is not compatible with your vehicle. You would need a newer Model Tester, and the 23104 adapter. 3257, 3258, or Allscan would be compatible with your 1987 GM Vehicle. Most other competitors testers of the same vintage were more expensive, but time is a great equalizer in the used market.GM Data streams changed every year and required constant updating by the scan tool manufacturers. Starting in 1996 with OBDII, testers became easier to use and more generic, however it can still difficult to keep of with the proprietary data streams.

Sounds like it could be weak fuel pump.Check your fuel pressure and if its not within the specs then replace the pump and filter.

You can find them at www.rockauto.com and you just splice them into the return line.

on the dryer there is a switch with 2 wires, disconnect connector and bypass the two terminals with engine running you will hear compressor clutch click and engage...if yes feel low pressure tube for cold ..if it does the switch is defect if not low Freon in system hope it helps

Just a rough explanation. First gear is the low clutch engaged by power to the 1-2 and 2-3 solenoids, second gear applies a band by power to The 1-2 solenoid turned off. Third gear, however, both solenoids have no power. If you are showing power to any solenoids, there is an electrical issue. If the solenoids shut off, the direct clutch is worn and I must say this is very, very common for this clutch to fail.

you need to remove the transmission first remove the oil pan if small parts of metal inside the transmission pan there is no electronic that control the reverse hope it helps

bad abs sensor , front wheels . you didn't specify a year , so be prepared to be shocked by the price of the replacement hub assembly . yes , you have to replace the whole hub !

Drive around for 30-40 minutes, then re-check. I'm assuming you're using some kind of OBDII reader?

Check all your maxi fuses in the power distribution box. You may not even have fusible links, but if you do, they would be tapping in to a direct battery source, and not on the firewall. More likely a maxi fuse supplies power to the ignition switch.

You haven't provided a lot to go on here but I'll take a stab in the dark. If you are somewhere that is unusually cold, maybe you just need to let it warm up. Could be the choke is not working, could be the choke is closing but wont open because the heat riser passage in the intake manifold is plugged up with carbon, could be the fuel pump is weak or the filter is plugged and the carb is starving for fuel even though the tank is full. To check the choke operation, take off the air cleaner lid before you try to start it and operate the throttle by hand while watching the choke plate. It should snap shut. If it does rack the throttle two more times, start it up and watch the choke plate. it should open just a little (maybe 3/8') on a cold day let it run on fast idle for a few minutes, as it starts to warm up the choke should open more. And be fully open after a little while. Given it's age it would not surprise me at all if the carburetor is not working right. If you are going to take it to a shop, look for a mechanic in his late 40's. I know that sounds weird but most of the young guys out there have never even seen a quadrajet let alone rebuilt one.

Normally, yes.The flasher should be in the fusebox - turn on the signal and get your ear close to the fusebox - you should hear the flasher clicking. There should be 2 flashers there - 1 for the turn sigs and the other for the hazard/emergency flashers.

If nothing works including the lights, you may have a bad battery cable or a burned fusable link on the starter.

Sorry we do not have these diagrams available.

If you don't have an oil pressure test kit to measure actual engine oil pressure, try replacing the oil pressure sender 1st and recheck. Its the cheapest and easiest to do .
