Chevrolet - 3500 :: 1993 - Truck Starts Surging / Tachometer Jumping From 2000 To 2500 RPMs
Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....

The truck is a 2002 F450 7.3 diesel with about 120k Miles.
While driving from 45-70Mph the truck engine stops for about 1 second and starts back up by itself. I thought the problem was the cps so I replaced it with a ford CPS. Today the problem still persists. The truck engine turns off and comes back on, the tach drops to 0 rpm and so does the speed.
The Check Engine Light comes on and so does the water in fuel light and so does the Check Gage light. After I turn off the truck and start it back up the truck does not show the lights.
I believe I found the issue, but can't look into it today. While I was moving some of the wires on the truck I found out that if I move the red/black bunch just a little bit the truck shuts off and comes back on when i let it go.
Pickup - Chevrolet :: 1973 - While Driving Away From Stops / On Highway Power Fades?
My father passed down his 1973 Chevy C-10 pickup truck to me and my family. It's been our 'runner' truck for many years going to the mountains for wood, lumber from the store, garbage and yard debris...etc. Unfortunately, it recently has been starting and warming up just fine, but once it's running as I'm driving away from stops or even holding speed on the highway the power 'fades' from the engine and it lugs like it is in gear, but flooded and lurches as the engine seems to 'catch up'. I have replaced the carb(holly quadrajet), fuel pump, fuel filters, battery, fuel lines, throttle cable, distributor cap (ceramic piece too), alternator and more...we still can't get it figured out. NOW the truck won't start or turn over - have we reached the end of it's life no matter what we do? What is left to replace? I don't think we can afford much more $ to fix it. We also found that somehow water was in the gas tank, which we think was from a kid in the neighborhood messing around. Could that have made a permanent issue?
View 5 RepliesChevrolet - Silverado :: 1995 / C1500 - Air Conditioning Blower Stops Blowing Air While Driving
I have a 1995 Chevy C1500 Silverado. The blower and heater work great when I start driving. After about 20 minutes of driving on high blower speed, the strength of air blowing out reduces drastically and eventually no air is blowing out of the vents. I can still hear that the blower is blowing air, but there is no air coming out of the vent. The Midas repair shop I frequent couldn't reproduce the issue on their short test drive (of course). They told me to bring it back to them whenever the problem occurs. I haven't had the opportunity because by the time I get out of work, they are closed and I am freezing to death every morning.
View 1 RepliesAstro - Chevrolet - Batteries - Alternators :: Battery Occasionally Stops Charging / Runs Down And Dies While Driving
So I have a very confusing problem. In my 92 Chevy Astro the battery occasionally stops charging runs down and dies while I am driving and will not restart via jump but must be fully charged. This first happened a couple months and several thousand miles ago but has occurred 3 times in the last two weeks. Both the battery and the alternator have checked out good, and the alternator belt is tight as a drum. What could this possibly be?
View 6 RepliesChevrolet :: 1986 - Oil Pressure Starts Dropping After Driving For A Bit
I have a 1986 Chevrolet El Camino with a small V-8 engine. The vehicle has 150,000 miles on it. It starts and runs fine. It does not use oil. My problem is the oil pressure. After the car runs for a short time, the oil pressure starts dropping. It will drop all the way to 0 if I let it. I have had the sending unit replaced and it did not work.
I have had two mechanics look at it and they have not been able to solve the problem. One checked it with a mechanical gauge and confirmed the low pressure. He suggested a higher weight oil and an additive. The other mechanic's solution was to raise the idle speed. I have had this vehicle since it was new and always kept the oil changed and all other maintenance done. I would like to keep the vehicle and complete any repairs necessary.
My question: Is the engine repairable economically or does the engine need to be replaced and what is causing this problem.
Chevrolet - Blazer :: CEL Starts Flashing Sometimes When Driving On Highway
Okay....I have an 01 blazer 6 cylinder 4.3. For a while it was missing fairly bad until I had the distributor replaced and the problem went away for about 2 months. Now it seems to have the same problem again so I am wondering if that wasn't the real problem. Here is what is going on. The tac needle bounces and it feels like the engine is misfiring. When I am driving on the highway sometimes the CEL starts flashing. Sometimes it stops and sometimes it doesn't. Plus now it feels like when it changes gears it's lurching. It only does that sometimes. The odd part is there seems to be no distinguishable pattern to the lurching. I think the misfire could be just the timing needs to be adjusted.
View 2 RepliesChevrolet - 2500 :: 1997 - Chugging When Truck Starts
1997 Chevy C2500 silverado... Ok, so when i go to turn my truck on she'll sit there and chug as it starts. usually a few seconds and then roars up just fine. However I've noticed a couple of distinct things. 1. when it does start i see a second or three of black exhaust come from the tail pipe. 2. if its been started recently. IE within 24 hrs it has problems. but if i leave it over a weekend then the first start has no problems. 3. Last weekend we replaced the Fuel filter and the first few starts there was significantly less problems starting but after 5 starts its back to doing it again.
I checked and the fuel pump does work, I've tried changing the fuel filter ( #2 above), and put sea foam into the gas tank hoping to clean out any gunk in the lines somewhere. It does turn on and when it does it runs great so i know its not having electrical problems as well as the alternator is charging like normal.
Im about to take it in for an oil change and see if that does anything, and I'm praying its not a clog in the Catylitic converter.
Chevrolet - 3500 :: 1996 - Won't Start Sometimes
I wait for the glow plug to stop before attempting to start. Then it's like Aaron Tippin sings, "sometimes she runs, sometimes she don't". It turns over fine. When it's running, it runs good. But most times it won't start. The fuel is being stopped somewhere. The in tank pump is working..I can hear it when I turn on the key. What else can I check?
View 5 RepliesChevrolet - 3500 :: Stinky Mushroom Smell In Van?
I suspect there are very stinky mushrooms growing in the debris inside the ventilation system. We live in Florida and the van sits outside in an area in our yard where stinky mushrooms grow at certain times of the year. I have tried spraying Lysol in the outside vent with the fan on full. That seems to have worked over time but can I dump some vinegar in there without harming anything?
View 1 RepliesChevrolet - 3500 :: 1989 V8 - Stalled When Decelerating And Would Not Start
I have a '89 Chevy 350 v8 in my boat. It starts fine, but then stalled when decelerating, and would not start. I smelled some gas fumes when trying to start it after it had died. It started up fine the next day without problems. The distributor was just replaced so I know that is good. Not sure if this is related, but occasionally it will diesel a couple cycles when I turn it off. Could this be the carburetor, or something else?
View 9 RepliesChevrolet - 3500 :: 2006 Express Van Won't Start In Cold
My 2006 Chevy Express 3500 (cutaway) 6.0L won't start when the outside temperature is below 35 degrees. Warmer than 35, it starts right up. Seems to be a fuel problem, as it fires, but doesn't keep running. I can start it by fooling around with the position of the gas pedal, but usually it takes a few minutes of cranking. My mechanic thought it was low fuel pressure and replaced the fuel pump- a thousand dollars later, it is no different.
View 15 RepliesChevrolet - 3500 :: 1995 - Truck Stalls With No Warning
My 1995 Chevy Silverado 1-ton diesel stalls with no warning at various times while driving, such as at intersections, on the freeway, coasting, idling. It may go days or weeks without doing it, then all of a sudden stall eight times in one day. My husband says it has sediment, such as rust, in the fuel tank causing it to clog the fuel line. We've replaced the fuel filter twice, and we keep the tank topped off with gas, but it still does this out of the blue at times. I no longer trust the vehicle and will not haul the horse trailer using it, which is why I have the vehicle in the first place. By the way, the problem began after the truck sat for several cold winter months due to drained batteries. After we replaced the batteries to get it running again, it began stalling like this on a semi-regular basis. If it is rust or sediment in the fuel tank, what can we do to fix that? Could it be something else causing the problem?

Have had the vehicle since 24k miles - currently at 43k and just started doing this in the past 5k miles. When cruise control is engaged, and we go over a bump (of decent size) the cruise disengages. Perhaps a bad connection with a sensor? I do not know the cruise system that well on this vehicle and would like to know where I should start looking.
View 1 RepliesChevrolet - 3500 :: 1994 - Intermittently Dies At Idle
94 Chevy W-4 wheel-lift wrecker 5.7L TBI4l80e trans
Had a run of about 100 miles round trip on Wednesday. On the way back running at 65 mph on the interstate, got a couple of quick muffler-end back fires and engine died. Coasted to shoulder. Had memory of almost exact same incident last year and it was dead ignition module. Fortunately had a spare (used) module in glovebox. Swapped it out and engine started right up. Remainder of trip didn't quit, but ran very rough, lots of stumbling and getting it up to 60 mph was a struggle. Also when I got on surface roads it died twice when I was sitting stationary. It would restart, BUT only after cycling key; if I just turned to the key to "start" from "on" it would crank but not fire.
Limped it to my tow buddy's shop where I freeload and told him the tale. He said, "throw those old spare modules away and get a new one". Called the local parts house and had them send two, one for installation and one for glovebox. Took for test drive and appeared to be running okay except idle was a bit low. Couple of hours later went on a call and first stop sign I came to, went "blip" and I'm dead in the water again. Same story as earlier, must turn key off and back on to get it to fire. Drove rest of day without incident. Yesterday, no issues all day, drove total of about 120 miles both highway speed and surface. Gassed up this morning and mpg was above average (yay!), actually about .5 above average which is significant improvement (about 6%). Success?
Today died four times while sitting still. Same having to cycle key for it to fire. Did some quicky t/s to satisfy my curiosity about the key cycle thing. With truck running, pulled fuel pump fuse to kill truck. Then reinserted and it started up without having to turn key to off. Tried same thing by pulling one of the module plugs to simulate loss of signal to ignition. Reconnected and again fired up without key cycling.
No codes at any time since this came up.
Swapped out the module since I had bought a spare, no change.
Ohmd the ignition coil and no problems noted. So far, only dies sitting still at idle.
Additional info:
Plug wires, cap, and rotor <1000 miles. Distributor low miles and negligible play in shaft. Pickup coil checks right in middle of ohm range. None of these, of course, should need to have the ignition key cycled to restart if they caused a stall.
Next up will be replacing ignition relay (had to order), but I'm not very optimistic.
Chevrolet - 3500 :: Slow Coolant Leak Above Rear Transaxle
I have a small leak of greenish fluid (appears to be coolant) coming from a silver/aluminum tube that runs the length of my van, just above the left rear transaxle. The leak seems to be in the tube, near a support that keeps the tubing flush against the undercarriage. It is a slow leak, but it is dripping onto the transaxle/transfer case, and is beginning to leave a small puddle on my driveway -- gets a little worse each time I drive. I haven't noticed much loss of coolant in the reservoir, so not sure what this is and how to fix it. I have a photo. I am thinking the tubing might be part of the heating system.
