Toyota - Corolla :: 1981 - Won't Start When Hot?
My 1981 Toyota Corolla wagon began to intermittently fail to start when warmed up about five years ago, and by fail to start I mean all lights come on but zero crank and no clicking sounds either. The amount of time I must wait for it to cool down and start again has varied between 20 minutes and today's record, 3 hours. This problem is common with older Toyotas and usually means the starter motor needs to be replaced, believe me I've looked into it, but here's the puzzler. I've replaced the starter motor two times and it has failed to solve the problem. I've replaced the ignition switch four times, same thing. I replaced the battery thinking maybe my old battery was losing mojo, but tears came to my eyes when it happened again.
I've studied how a hot starter head close to the exhaust manifold sees it's resistance go up, that the initial crank requires big voltage throughput. But an aluminum heat shield is built in and wrapping the starter in a heat blocking blanket is not physically possible with my configuration. What I haven't looked into yet is the clutch safety switch. I did receive the following bullet from a previous CarTalk query which read: "If a manual transmission, the clutch safety switch must be working and have low enough "on" resistance. Likewise with an automatic transmission, the neutral safety switch." I would love more detail about the clutch safety switch. I can add this interesting caveat to today's 3 hour record wait. I've gotten good a bump starting the car by myself. Today I bump started it in rolling reverse, re-parked it, and tried restarting again. Started right up when it wouldn't start moments before.
Toyota - Mr2 :: 2000 Cranks Fine But Barely Starts When Engine Warmed Up
My 2000 Toyota MR2 started to act up a bit lately.
I noticed that the car cranks fine, but turns over very weak. almost seems like it barely starts. This happens ONLY when the car is already warmed up. This does not happen when car is starting from cold start. Like, starting first time in the morning is fine, but after 10 minutes of driving, then turned off, the subsequent starts are weak as a fart from a butterfly. But it does start, and when it does... it seems to drive okay.
Now, I've been hearing it can be leaky fuel injectors, or... Mass Air Flow sensor, .. or .... bad fuel pressure..(which may be part of leaky injectors?)
Toyota - Corolla :: 1978 SR5 Won't Start And Sometimes Cranks Right Over And Goes Like Blazes
My '78 Corolla SR5 with 2TC engine, starts sometimes, and sometimes not. If she has rested in the carport for a few days, she cranks right over and goes like blazes. After a twenty-mile run, if I shut her off, she won't start again. Not a sound not a click nothing. But if I leave her alone for a couple days, she cranks right over. I need to take the old girl through emissions pretty soon. I don't want her to go into a coma in the emissions bay. Her mechanics can find nothing wrong.
View 9 RepliesToyota - Corolla :: When Turned The Key, Sounds Like Cranks But Car Would Not Start
I have a 1996 Toyota corolla. it has been working fine until recently. I had problem starting the car intermittently. When I turned the key, it sounds like it cranks but the car would not start. If I tried it again after a minute or two, it would start again. It happens twice to me already so far. It has been around 4000 miles since my last oil change. And my engine oil has been leaking slowly for years (probably due to bad gasket) and I checked regularly and made sure the Engine oil is filled up to Full level. I haven't brought it to a mechanics yet but I would like to know what could be the issue.
View 4 RepliesToyota - Corolla :: 2000 - Cranks But No Start / Pump Works But Does Not Prime
My car was performing poorly then Stalled while driving, no start since. Put starting fluid in open throttle body for 5 secs, then tried to crank.
fuel pump doesn't turn on (can hear it) for 2 seconds When the Ignition switch is in ON position, You can hear it when cranking in Run position though. So this makes me think that Its not building enough pressure
Pulled it out, hooked it up to a 12V batt and it works.
Someone else changed the spark plugs. Fuel comes of of the line just before the fuel rail. Doesn't squirt like there's a lot of pressure.
Pulled the injectors clean them put them back in with new O rings. Fuel only came out of 2 injectors when cranking.
Pulled the spark plugs check for spark while cranking. They all spark. Put new ones in.
Pump does send fuel when cranking which means the pump, and pump relay should be working I assume.
Toyota - Corolla :: 2009 - Noise After Turning On Ignition But Before Engine Starts Only In Very Cold Weather
have an 2009 Toyota Corolla 62K miles. If the car sits out 8 hours or more in VERY COLD (zero degrees) weather makes a 1-2 second clashing/sparking noise the split second after turning the ignition on but before engine starts. I tried to attach video/audio. The car starts and runs fine. isn't a ticking or knocking or tapping noise assoc. with bad engine. It isn't squealing noise assoc. w/ serpentine belt. I've been waiting for it to get cold enough to leave overnight at Toyota dealer. I keep wondering if it isn't related to the botched oil changed at the Toyota dealer a couple yrs ago when they forgot the oil & I ran car about 30-60 seconds. At the time, they said all was okay and did compression test (Cyl 1=178psi, #2=175 #3=180 #4=178) all within the normal specs 145-189. I got a 2nd opinion at another Toyota dealer at time who removed valve cover and inspected cam caps and scoped cylinder walls and said all was okay and compression good. No mechanical problems- uses no oil, check engine light not on, etc. What noise is and why just when very cold and car sits out long time?
View 18 RepliesToyota - Pickup :: 1981 - Refuse To Idle / Only Sputters And Runs Rough
I have a 1981 Toyota pickup. when i start her. she starts fine, but sometimes she will idle fine, and then suddenly refuse to. it seems to be random. i can keep her running if i keep my foot on the gas just a little, to keep her rpm's up. but have to put her into N and keep my right foot on the gas and my left on the brake to stop her when she refuses to idle. when she does this on the freeway, it just sputters and runs rough, but as long as i have the gas on, she keeps going.
I don't know what it is that regulates the idle to keep her going when my foot isn't on the gas. also her serpentine belt is slipping. the one attached to the alternator, i can see her charge voltage dropping when she squeals her belt. that i know how to fix, but i'm wondering if it's that, that is the issue? i was told that, but i don't think her serpentine belt has anything to do with her idling. i was told how to raise her idle on the throttle cable and the Idle screw, but is there something else that regulates her idling?
Toyota - Cressida :: 1981 - Windows / Heater Works Intermittently And Turn Signals Quit?
Toyota Cressida 1981 5ME sedan. Problems with drivers kick panel fuse, breaker block due to water damage and ?. Long story! Some things ( windows, heater etc) work sometimes for months then dont work. Turn signals were first blew two fuses then quit. Flashers fine. Horn stopped then caught up at next left turn. etc. etc. Have replaced, tested, cleaned and am still doing so. At one time every warning light was lit. now only battery light is on, battery is charging. Windows and heater quit, they worked two weeks ago. and Haynes book and owners manual are incomplete and confusing.No Chiltons for this car. Had power steering pump replaced last year, mechanic moved, knocking noise began again in 2 months got worse. Just last week figured out that the nut on the power steering pump pulley was gone.

Toyota - Prius :: 2007 - Air Conditioner Blows Mainly Warm Rather Than Cool Air
My 2007 Prius air conditioner blows mainly warm rather than cool air. I took it in for repairs and they replaced the high pressure hose but it is still not cooling the car. The dealer has had the car for 2 weeks trying to determine what the problem is. They tell me it should be blowing 42 degrees but is only blowing 62 degrees. They think that it might be the invertor that cost $1,000.
View 1 RepliesLexus GX 2004-09 :: GX470 Cranks And Starts On Second Try
This is a problem that started a couple months ago, and I've taken it to two separate mechanics. Neither knows what the problem is. Basically, most times I try to start the car (~75% of the time), it cranks, and keeps cranking, but does not start. I have to pull the key back, and turn it again. Then it starts no problem.
Not fuel related, as pushing the gas while it's cranking and not starting does nothing. It's not regular either; sometimes it starts first try on a cold start, sometimes not. Sometimes it starts first try after driving for a while, sometimes not. It's a 2004 with 130k miles.
Interestingly, I am pretty sure this started when I got a new key. The physical key shell snapped and separated from the blade. I ordered a new one, and put the old transponder into the new key shell. I haven't had any sort of anti-theft problems afterwards (unless this is one).
Toyota - Pickup :: 1991 V6 Overheating At Idle And Cool Down Again Once Began Driving
I have a 1991 V6 automatic Toyota pickup. The transmission has ~230,000 miles, but the engine has been rebuilt and probably has less than 5,000 miles on it. I am having overheating issues in both departments.
Engine overheating: This has started fairly recently. My truck began overheating at idle (usually at longer traffic lights) and would cool down again once I began driving. My coolant was low, I took it to a shop, and they fixed a small leak. Fast forward a few weeks and it happened again, and this time when I turned on my heat full blast to take heat off the engine it blew cool air until I started driving. Took it back, they found no more leaks, and couldn't duplicate the overheating symptoms. They also said the fan and thermostat seemed to be working fine. It seems to happen sporadically, regardless of coolant levels.
Transmission overheating: Firstly, my truck tends to delay/hard shift when I first start it in the morning. Once the engine warms up it goes away for the most part. I took it on a 100 mile trip camping on a fairly curvy/hilly forest highway and the A/T Oil Temp light came on. This has happened before when I took it on forest roads, even after a recent ATF flush. Needless to say I had to stop a few times to cool it off. It felt like the transmission was working too hard at a flat 60MPH (2,500-2,800RPMs). A couple times the RPMs were pulsing like it was switching gears back and forth. The next day driving in town everything was back to working order.
I'm not sure if these two things are connected... but they never happen at the same time. I'm taking it to a transmission shop but I want to make sure they don't try to rip me off unless absolutely necessary.

View 1 RepliesGolf IV / Jetta IV :: On Every 4th Or 5th Start It Cranks And Then Finally Starts / Sometimes Stalls
Recently my 01 Jetta 1.8T has started to not start like it should. Say every 4th or 5th start it cranks and cranks, I see the tach eventually flick a couple of times and then it finally fires up. It's also stalled while I'm driving, say when I stop at a light but will usually start up again ok.
After the not so good start I get the impression the car is kind of surging while driving - like a fuel supply issue although maybe the fuel pump has nothing to do with supply after starting?
So anyway my thought is perhaps fuel pump issue? I decided to try and search for my issue or fuel pump issues but it talks about things that happen when you open the drivers door which in my case isn't working properly (i.e., I believe it is a DLM as my windows sometimes all go down and I don't get any chime or door light when the door opens).
So just wondering if based on what I'm experiencing if fuel pump sounds likely and perhaps what further tests I should run. My battery is new and the engine does crank pretty good if that eliminate it. I guess I should be thinking fuel filter perhaps also.
Pontiac - Grandam :: 2004 - Cranks Fast Starts Slow
I will try my best to describe the problem:When the car sits for quite a few hours it basically will try to fire up , but can take 4,5,6 seconds before it will actually start. It is a fast turn over just as if your car was going to start normally, but it just takes time. This is not a slow turn over as in a battery problem, or a very cold weather thick oil problem.After the car starts the initial time, you can turn it off and start it and it fires right up.
When I turn the key to the on position, I can hear the Fuel Pump. I have tried doing this a few times in a row, but it doesn't work for the initial start.
This has been going on for about 8 months, and I have basically ignored the problem. The last few starts the same issue persisted except instead of firing up after 4,5,6 seconds it just shuts off. After this I turn the key over and it still fires right up.
Ford F-150 - 1997-2003 :: 2001 4.2L V6 Cranks Perfectly But Starts Sometimes
Doing some research for my dad, we got a 2001 F150 with the 4.2L v6. Recently, we've been having an intermittent starting problem. It'll start, run & drive perfectly with no problem some days. Then some days the truck wont start. It will crank perfectly fine, sometimes start & then run rough for about 5 seconds then die again. Usually happens when the truck is warmed up & has been started, driven & shut off multiple times. We've replaced the fuel filter & the pcv valve i believe & still no luck. We take it to our mechanic & it starts right up every time for him. This problem has me, my dad & our mechanic stumped.
View 1 RepliesFord 6.0L Power Stroke Diesel :: Consistently Cranks For Around 5 Seconds Before It Starts
Where to monitor or what to check. The past few weeks this truck all the sudden went from a quick starter(barely hit the key and it would pop off) cold and hot to one that consistently cranks for around 5 seconds before it starts. Doesn't matter if I wait for the glow plug dash light to go out when it's sat for two days or if the engine has a ECT of 198 F and was just running 5 minutes prior...it still cranks over for 5 seconds before starting. Seems like it's an electronic issue vs mechanical, but that's just a guess.
The truck runs, drives and tows excellent outside of this starting quirk...so I know I shouldn't complain but this isn't right from what it used to start like and seems like it's a warning that something is likely to fail down the road. I'd Rather find it now than when 100's of miles from home if possible.
I updated it with better dummy plugs, standpipes, STC fitting, rebuilt FICM, 2 fresh batteries, new fuel pump, ICP sensor all within the last 10K miles. I scanned it with a code reader and found no codes in the history and the check engine light is not on.
Monitoring with a Scan Gauge all inputs seem normal for what I've read on this website with the exception of SYC it says 0? Which should mean it would never start I think but yet it does? I checked my code numbers from the list and I had it entered correct. Is this my issue a bad crank or cam position sensor?
