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?

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?

96 Chevy express 1500 V8-305. Have a P0305 code...Misfire on 5. Let me tell you everything I have done so nobody wastes their time.
I have, replaced the entire ignition system, "EVERYTHING" including a new distributor...Not the problem... I did a compression test...Not the problem...injector cleaning...not the problem.
When I moved the wire harness that goes into the "spyder" fuel injector system the engine smoothed out. I untaped the harness from around the plug and applied pressure to each wire the engine smoothed out. The back row 2nd pink wire seems to cause the most reaction.
My question is...Is it the wire harness or is it the injector system not reading plug? or could it be a combination of the 2? If I replace the wire harness might I still have to replace the injector system?

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?

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.

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.

View 5 RepliesChevrolet - 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....
Chevrolet - Cobalt :: 2009 Will Not Start In Cold But Only Sometimes
My Chevy Cobalt will not start when it is cold (when water freezes)...but only sometimes. When you go to start the engine, it will initially turn over but does not ignite. Then, the second time if you turn the key normally no sound will emit. However, if you put the key in and only turn to get the lights on the dash to come on and THEN turn the key, it will turn over, but no dice. This past time a code "engine pwr reduced" came up, but that doesn't always happen. When you wait four hours or more, it will start like normal accompanied by the check engine light. The check engine light goes off the second time you start it after the non-start.
I have taken it to a mechanic and they have not been able to reproduce the problem, even when it was cold enough to theoretically have happened. He said it might be an issue with the body module which explains why the ignition switch code comes up when you run it through a computer, but since this is such an expensive fix he said he can't recommend I get it done until we know for sure. So there is a pattern, this happens about every 2 months and then the issue clears up for a while.
What is going on??? Will there ever be a way to tell what is wrong (and fix it) without a mechanic reproducing the issue?
Chevrolet - Suburban :: 2005 - Won't Start When Cold?
I have an '05 Suburban with starting issues. When it's cold out (below 40 degrees) and you turn the key, all accessories come on but truck will not crank. It then seems like the power just cuts off.......dash lights go out but gauges are fixed in place and a couple of seconds later, I hear a strange buzzing noise from the dash area behind the radio and the gauges will then go to power off position. Then if I try to start it, there is nothing, no lights on dash, no starter engaging, no clicking of the relays, nothing. I tried, on a hunch to disconnect the ground lead from the battery. Had it off for 10 minutes or so, put the cable back on, tightened it down (wasn't loose to begin with) and it started right up first try in 20 degree weather. I had previously had the battery and alt checked and both were good.
View 3 RepliesChevrolet - Malibumaxx :: 2006 - Intermittent Starting On Cold Mornings
I have a 2006 Chevy Malibu Maxx with under 100,000 miles. Battery 1 year old, starter 3 months old. On cool or cold mornings I have intermittent starting issues. All lights come on, instrument panels gauges and indicators function right, no clicking or any noise. Just won't start. Typically if I come back in a couple of hours, it starts right up. Once it starts, I have no other starting problem with it the rest of that day.
On Christmas eve morning it wouldn't start. It didn't start for 2 days. I jumped it and got it started once, but after revving it and sriving it for 10 minutes I turned it off and tried to start it again - but couldn't. I wouldn't even jump after that. 2 days later, I had it towed to a shop where they removed the starter and greased the connections - and it started. They then sent it over to a Chevy dealer who checked all the codes (It never turns up any codes when it doesn't start) - but since there were none, they flashed the computer and started it 20+ times - no problems. They sent it back to the shop who also started it a bunch of times with no problems. They sent it back to me and it worked for another week or so before it started happening again.
It is not every morning - only random mornings. Except for that one day, it will always start later on in the day.
Chevrolet - Mailbu :: 2006 - Brakes Pulse Briefly After Starting Engine Cold Or Hot
2006 Chevy Malibu Maxx. This just started a little while ago, before I replaced front brake pads. after I start the engine whether cold or hot, the brakes will pulse briefly when I step on them to get the car in gear. It feels like the ABS, but it only does after a fresh start, and not when braking. The car stops fine. The brake pedal is a little spongy, probably because I didn't bleed them, but the pulse was already happening so I don't think they are connected. there are no warning lights on at all. Also, it doesn't do it 100% of the time, maybe 80 to 85%.
In order to bleed I guess I need a scan tool, but the bleeding procedure is a bi-directional function which is not supported by most of the gizmos available. Know of one that might work without spends thousands?
