Camaro :: Engine Starts And Runs Well For About 15-20 Minutes Then Shut Down


Jan 2, 2012

Here is my question.. 94 Z28 38K 6spd. Starts right up and runs well, for about 15-20 minutes then will shut down( like the key was turned off) When this happens I have no signal to either the ignition module or to the injectors.

This car was damaged by an idiot that flooded the dist. with coolant doing a flush. They replaced it with a Advance auto remain. This is when the trouble started. I did replace the I/M with an AC OEM Module, no change, verified all wiring from the computer to the Dist. and I/M. All checked out. I am thinking that the cheap remain unit is my problem and am looking to get the MSD Opti spark system to hopefully fix and to prevent this problem from happening again.

I cannot retrieve codes (94 won't flash CEL codes). Is there any other method of diag I could use to verify my suspicions. Oh, there is not response from the Tech either once the engine dies.

Prius (Gen 3) Fuel :: Engine Starts Up And Runs For About 4 Minutes

My Prius waste gas by always starting the engine. Even with the battery indicator at full charge. Every time the Prius is shut down, like leaving the car to go into the store for 3 minutes or more or backing Prius out of garage, the engine starts up and runs for about 4 minutes, regardless of being fully charge or not.

Dodge - Neon :: 1995 - Starts / Runs For A Few Minutes Then Stops

Camaro :: Bogs Down And Has Terrible Acceleration When Runs For About A Minute

I seem to have fixed all the other problems i was having except 1. I blew the head gaskets on my Z and it sat in the garage for about 2 months. Tore it apart and changed everything, now I have an issue when it runs for about a minute or so when i get on it, it bogs down and has terrible acceleration. I just changed the opti, coil, icm, oil pressure sender, new plugs. Engine light was on previously gave codes, 48 and 29. swapped out my MAS sensor... checked fuses and there was a bad one for the air pump, changed it and the ses light went off.... I am thinking a fuel filter needs replaced? I am at a loss here. It ran perfectly fine before i blew the gaskets. its a little rough at idle, but i had cut my cat off and ran 3" out the back to the flowmaster....

Prius (2004-09) :: If Engine Runs Out Of Oil / Will It Shut Off Automatically?

Title sums up the whole post. My Prius tends to use a bit of oil, I don't know the exact numbers just that it can't go without a couple top-offs between 10k oil changes. As much as I love this car it's because of that fact it will be sold after it's paid off as I've never seen a car that uses oil and yet drips none onto the ground.

Anyways it's because of its oil consumption and me not being used to having a car that needs its hood opened between oil changes that I've worried and wondered if I forgot to check it and it gets low enough to make the oil pressure drop will the hybrid system turn the engine off assuming I'm going slow enough for it to do so? I understand if I'm going over ~40mph the engine has to be spinning to prevent MG1 from over-revving.

So lets say I'm doing 65 on the interstate and the triangle lights up then I slow down and come to a stop will it prevent the engine from turning back on, or I'm sitting at a light and the engine is running because the heater is on then the oil pressure drops will it prioritize protecting the engine over the heater? Or is it like a typical car it will warn me but it's up to me to stop the car and turn the engine off as fast as I can to lessen the damage that is being done?

Prius (2004-09) :: Engine Idle / Won't Shut Off And Runs High

I've noticed the last few days that my Prius seems to be dropping MPGs horridly (even worse than the typical winter drop). The engine will idle hard and loud when stopped sometimes or when braking even. I noticed this morning, when I am braking to a stop, the MPGs are registering at 75 or below and it's running when idling and it seems to be running the gas engine more. It will sometimes shut off at a stop light, but hardly at all the last few days regardless of if it's been running 5 minutes or over an hour.

I thought maybe it was because it's cold-- we've dipped to single digits, but have been above 30 or so the last week or two and has only happened in the past two or three days. It happens at start up and at the end of my hour long commute to work. I've turned off the defrost and heat and it still does this.

She's a 2005 and has just over 105,000 miles. I just had her oil changed, a fuel injection cleaning and spark plugs replaced two days ago and had the inverter serviced and recommended transmission work done at 100,000 miles. Her water pump was replaced in the last year with the recall. I just replaced the air filter. There are no warning lights, so I"m not sure if anything would show up with the codes. I'm worried because it did not do this previously, and started to as soon as I got the car back from the injector cleanings and plug work...

Dodge - Neon :: 2001 - Runs Hot / Radiator Fan Turns Off When Engine Is Shut Off

My son's 2001 Dodge Neon tends to run hot. The radiator fan comes on while the engine is running, but does not stay on when the engine is turned off, even if the temp indicator is in the range where the fan should be on. Wiring diagram looks like the fan control relay only works when the ignition is in ON or RUN, which would indicate that this is the way the electrical system is designed, but that seems weird...I thought the fan is supposed to operate even if the engine is turned off. We have already replace the thermostat.

Passat (B5) :: Engine Runs For About 3 Seconds Then Starts Rattling And Stalls Out

One of my friends recently asked me to change the timing belt on his 2004 Passat 1.8T. I put on everything as instructed by the manual that the parts department gave me. However, when I start the engine, it runs perfectly for about three seconds, then starts rattling, and stalls out. I took the belt off and put it back on three times and yet, it still continues. This rattling seems to be coming somewhere from within the exhaust system near the engine and sounds like a back-fire. The check engine light also appears when this begins happening. I replaced everything, water pump, pully, tensioner, and etc. Note, I am a professional mechanic and have worked on several Volkswagen cars, including my own, but I never encountered a problem like this one.

Prius (2001-03) :: Engine Starts And Runs For A Few Seconds Then Bucks And Stalls

My 2001 Prius (230,000 miles) is unusable. I can clear the codes. The engine will start up fine. After a few seconds it starts bucking and jerking as if the engine is trying to engage something that won't turn and finally stalls. It is similar to a manual transmission car's action if you fail to push the clutch in when you stop the car. What the engine is trying to engage? I don't have any scanner to read the codes.

Prius (2010-12) :: Engine Won't Shut Off / Keeps Running For A Few Minutes

If I put the Prius in park while I get out and mail a letter, engine temp is 190, I can get back in and drive off on electric, zero rpm's. However, if I push the start/stop button, mail the letter, and restart the engine (temp is still 190), I cannot get the engine to spool down. It keeps running for a few minutes.

Ford F-150 (2004-2008) :: 2005 STX - Hard / Rough Starting When Engine Shut Off For More Than A Few Minutes After Driving

My 2005 STX 4.6 fuel pump crashed a couple of months ago. A couple of days after having it replaced I started having hard/rough starting problems accompanied by a 0300 and 0301 code. I reset the codes several times and they only come back during the 3rd or 4th hard start, never while driving. The hard starts occur after the engine is shut off for more than a few minutes after driving. I have replaced the plugs, #1 COP, remaining COP boots, Cam Pos Sensor, Fuel pump drive module and had and FI. Also had the fuel pump replaced again on warranty thinking maybe a bad check valve. Again...it worked perfectly for a day and now I'm back to square one. Haven't gotten any codes YET but its only been a day. Bad injector? EGR?

Cavalier :: Radiator Fan Starts And Within Few Minutes Engine Radiator Fan Stops - Fuse Blown

I start the car, with AC on, radiator fan starts and within a few minutes the engine radiator fan stops working, idles rough since the AC compressor pump keeps cycling on and off and engine starts to overheat. After shutting down I check the engine cooling fan fuse and it sure enough is blown.

How do I determine as to where the short is? Is the short in the wiring somewhere or can the actual motor short out?

Regal :: 1988 / 2.8 Runs For 5 Minutes Then Stops

We have replaced crank position sensor, ecm/ coil packs and computer. got good pressure on fuel rail. Starts cold, will run normally for approximately 5 minutes before it dies and will not start.

Sometimes we can hold accelerator to floor and it will "hit" a few licks but promptly dies when accelerator is released. We've checked fuses and relays; what are we missing?

Passat (B6) :: V6 Runs Rough For 1 - 2 Minutes At Startup When Cold

My V6 3.2l runs very rough for 1-2 minutes at startup when cold i.e. the first startup of the day, or after it has not been driven for several hours. Is this normal? I understand this might be something to do with the 'anti-knocking' feature. But I only use RON 98. Also I can here something like a tappet sticking when idle all the time. Is this normal, is it just a noisy engine design? The car has only done 1800kms.

I have a 93 Camry that quit on the highway. No spark, crack in condensor replaced distributer. Still not run. Rotor not turning, replaced timing belt, main engine fuse heating up replaced that.
