Chevrolet - 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?

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.

Recently the check engine light came on and coded out to the mass air flow sensor. I changed the sensor and cleared the fault code, but after doing so the car wouldn't start. After many failed attempts to start the motor, I disconnected the positive lead at the battery and reconnected it a few minutes later. The car started and ran smooth, however the check engine came back on and coded out to the mass air flow sensor again...
I let the car continue to idle and disconnected the lead at the sensor how the motor would react; it continued to run smooth....I then reinstalled the old air flow sensor and engine continued to run great...So with all this said, car runs great when check engine is on and code is not rest, however, car will not start upon clearing the code and resetting the light......is it safe to assume the computer is going bad and needs to be changed?

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?

Problems started 2 days ago, after the weather got colder. Related? Can hear starter engage (loud click) but not enough juice to spin the engine. The only way to start is to get the rolling and pop clutch. Will not start when I attempt to jump start. When running, battery emblem in the instrument cluster is illuminated and voltage gauge shows very low. Batteries (two 12-volt 800cca batteries) old and worn out? Had alternator went bad?
View 19 RepliesChevrolet - Suburban :: 1996 - Dry Start Only When Engine Warm
My Burb starts right up when the engine compartment is cold. Can barely touch the key and the thing fires right up.
Once engine compartment is hot (operating temp), I shut off the motor, let it sit for a few minutes and I get about 3-5 seconds of dry start each time I start it. It fires right up, runs great after that dry start period.
The dry-start behaves as if it's starved for fuel for those 3-5 seconds.
It's a K1500 with a stock 5.7l (350 ci). 180,000 miles and the entire drivetrain runs like a top. Only mod I've made is a K&N cold air intake.
Here's what I've done/changed recently (i.e. within the past 5k miles):
Fuel pump, OEM installed by dealer.Fuel filter.Ignition control module, BWD.Ignition coil, BWD.Crankshaft position sensor, GM OEM.Engine coolant temp sensor, BWD.Oxygen sensors (all four), GM OEM.Catalytic converter, replaced one of the two.Plug wires, BWD.Plugs, Delco OEM.Distributor cap and rotor, BWD.Cleaned ground connection (bolts to frame) for fuel pump.Alternator, new not reman.PCV valve.Battery.
Full diagnostics by a very qualified shop two weeks ago, no bleedback from injector spider, fuel pressure solid and holds perfectly. After 90 minutes of troubleshooting, the mechanics finally gave up.
One last thing with potential that I can think of is that I started running ethanol-free gas around the same time this issue surfaced. Not at the exact time, but at a relatively similar time. Gas mileage has increased by 40% and power increased, hard to blame "bad gas."

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.

View 1 RepliesChevrolet - 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 3 RepliesChevrolet - 1500 :: 1996 Chevy Engine Hard To Start When Cold
I have a 1996 Chevy Cheyenne pickup with a fuel injected small block that has 50k miles. Earlier this summer the truck developed a problem where it is very hard to start when cold (after sitting overnight or after sitting for many hours on my flat driveway). When the engine is cold (say the first start of the day) I can only get it to start by giving small bursts of cranking power to the starter. That is, it won’t start if I hold the key in the cranking position but is more likely to start if I give it a short burst of cranking power (when I hold the key in “start” position) for a second or two.After the first start of the day, the engine runs fine and subsequent starts are quick and normal. The “Check Engine” light is not on and there are no trouble codes…. Other than hard starting there are no issues with engine performance.
