#225 of 444 Taillamp Dilemma
Oct 26, 2008 (7:08 am)
2002 GMC Sonoma. No foglamps installed. Good taillight bulbs. New headlight switch. Voltage at taillight connector. Ran a jumper wire from battery to taillight and it would not light. Grounded with no change. All other lights work fine except license plate lights. Fuses have all been checked. Relays are fine. Finally have installed my own taillights on the rear bumper, but I'd like to fix the original ones. Anyone have any ideas?
#226 of 444 Flex fuel sensor wiring problem
Oct 26, 2008 (12:17 pm)
my flex fuel sensor has an error. so i figured its either the sensor that has went bad but i checked the voltages from the wiring harness and they are not what they are supposed to be. anyone know where the wiring harness is routed or how i can trace the problem. thanks

I have a 93 sonoma with the 4.3L and 4WD. recently I have been having some electrical issues. A few days ago I was driving and the engine just died. I let it sit for a few moments and it would start back up. The next morning i needed a jump to get it going. So i thought it was the alternator, took it in and had it tested 3 times. Passed all 3. The guy at the autoparts store said to check all the grounds, which i did, and even replaced the negative batery cable. now the voltage will fluctuate from about 10 to 16 volts. To make the issue more confusing, 1st gear on the transmision has never worked like it is supposed to. but now... when the voltage is high like it should be, the transmission shifts smoothly and 1st gear has all the horsepower you would expect. but as im driving the voltage will drop and bye bye 1st. Any ideas on what i can do to fix the electrical??

I have just recently purchased this truck that had a motor swap with another 2.2 liter and after the swap they didnt strap the positive cable down and it burnt up , they replaced the wire and it ran fine drove it for a week and then it died now the truck turns over fine just wont start , so i replaced the fuel pump and still nothing ,so then i hooked my snap-on scanner to it no codes but i noticed on battery voltage with the key on only reads 5.0 volts and theres 12.0 at the battery i checked the grounds but maybe im missing something any suggestions?
#229 of 444 Voltage meter jumps when cold
Nov 03, 2008 (5:48 pm)
When the cab is warmed up the meter is fine, I had alternator replaced 2 times, new battery, Check cables at battery and on starter.While cold and rev eng,lights go dim then meter drops I am going insane with this problem. I am wondering if the instrument cluster is bad since cold contracts and warm expands, Maybe volt meter gauge itself , maybe the starter? Any suggestions would be appreicated. One person told me a ground problem. If a ground problem wouldn't it do it all the time? Thanks in advance
#230 of 444 99 S-10 Starting Problem
Nov 15, 2008 (1:07 pm)
My 2.2 S-10 started having issues starting, at first I took the starter out and since it was o.e.m with150000miles. replaced with brand new (not rebuilt). Still had the same problem so I traced all the wiring where it went, tested the relay by swapping with headlight relay, and everything looks good. Took the plastic cover off pos. terminal and cleaned all corrosion off. Yet I'm still having the same problem. The starter kicks the bendix out when I turn the key and just spins, it wont turn the engine over. I have been informed by Napa that there isn't a shim pack for this model year. does anyone have any ideas.

Just wanted to update found the problem in case anyone else runs into this. The flywheel is not connected any more don't know if bolts are broken or vibrated out. will update later. Found this by pulling inspection plate and watching as someone else turned key. Saw flywheel spin but didn't turn engine. had helper stop and was able to spin flywheel with fingers.

My flywheel broke near the C/S under warranty, they installed the transmission wrong at the factory. There was even a service bulletin on it.It broke at 10 K.

Check for the ground connection, it's a tab between the motor mount bolt and the motor case, it could be broken !
I had that problem ...
Hope it'll help !!
