Toyota Camry Problem Report
Toyota Camry "No start" Due to Pickup Coil Failure Inside Distributor
The pickup coil inside the distributor can fail and cause a no-start condition. There have also been some failures of the radio noise suppressors inside the distributor which can short out. It is recommended to replace the whole distributor with a complete genuine Toyota distributor if any of its components fail.
Tricky to diagnose coil failure because you may still have a spark at the plug and think it is some other problem, but in fact the spark is too weak to provide ignition. At 190,000 miles I had the same symptoms (car cranks normally, sounds like the engine wants to catch but never does) So I replaved the coil again, didn't fix it, and after further research learned about the stupid radio filter capacitor inside the distributor will overheat, and the potting will melt. This allows the capacitor to ground out the whole ignition system so the car won't start. Rather than removing the coil again to gain access to the capacitor, I just cut the wire lead from the capacitor going to the terminal connection. Thuis solved the problem. Crazy. For those old enough to remember mechanical distributors, this capacitor was called a condesor and served the same purpose - eliminate radio interference from the distibutor. By the way, cutting the lead did not affect the radio at all!! - Visitor
the car runs great but only for about 10 miles. then it shuts down as if there is no ignition. after it cools dow for awhile it starts again - chef d
I was driving on the freeway (rush hour traffic, of course) when all of a sudden the engine just died. Will not start. Turns over. Further checking reveals not only no spark at the plug, but also no spark going into distributor. AHHHHH!!! - Visitor
blown fuse on am2 circuit, traced short to noise suppressor in distributor, replaced distributor w/reman. - Visitor
Engine couldn't start, no spark - Visitor
Ran like it was onlt using 3 cylinders. Replaced Distributor - speedrover
While driving the car after it was warmed up it would just stop. Could not start again until it cooled down. Let car idle in driveway for about a half hour and it stopped. Checked for spark and there was none. Waited about 15 min and it was back. Replaced complete distributor and car runs great. This has happened twice to this car. First around 140,000 mi and then around 230,000 mi. - Visitor
starts runs fine for 2-ten mins. then dies ; wait 2-3 min restarts then dies. removed capacitor inside distributor - Visitor
Also had this problem right after I bought car (used). $200 plus $50 tow for a $10 part. - Visitor
car turned off while driving, will try with new distributor. - Visitor
The ignition coil, which is attached by screws to the disributor body, can fail because of heat, age, etc. This will cause a weak spark. The engine will almost catch, but will not start. The coil potting had cracked and this resulted in a weak spark. About 50,000 miles later, I had the same symptoms and replaced the coil again. Problem continued and through internet research I learned that the radio interference capacitor had melted, and this shorted the coil to ground. You could replace the capacitor, but it is easier to reach in with small side cutters and just clip the connection. These capacitors were also called "condensers" in older distributors. Cutting the wire did not affect the radio. This apply to all 4 cylinders w/the distributor. - Visitor
AM2 fuse blows every time the ignition switch is turned on. Thought the problem was related to the fuel pump but when the pump was disconnected, the fuse still blew. Read this thread online and followed the diagnostic procedure by removing the connectors to the distributor. Replacement fuse did not blow when ignition switch was turned on. - Visitor
Would not restart and coil had a crack in it - Visitor
Car died while driving and engine would not fire.Found no spark at plugs so went to distributor and removed cap.Found a fair amount of oil inside cap and finally determined that the internal oil seal inside the distributor had failed,allowing oil into the coil area and shorted out the coil.Purchased complete distributor assembly,installed it and it has been just fine so far.Toyota dealer of course wanted a huge fortune,($979 not including tax or shipping for one!,and it was not returnable).So I went online and found a new one with a lifetime guarantee for $108 and free shipping and it was returnable.Lucky me.It has been about a month and it still runs fine. - Visitor
I had someone with the same problem. No start. Inspected the internals of the distributor. Dist Cap had the coil carbon button missing. Replaced it. Still no start. Checked the coil and ohmed out within specs. Recommended replacing anyways and it started. Cool. The next day it went back to no start again. Checked the module. Good. So we took a chance and replaced the Dist with a salvage yard unit (I know... bad idea) But it fixed it and has run for a while now.
I think the key here was that there was no spark AND no fuel pump start up.
Most Coils will crack across epoxy. So its usually a good first step. - ECMech58
Every couple of days ill turn car off and go in the store and when i get back in the car turn key and nothing happens. If you wait a a while car will start again. Any ideas - ballbat
Started to sputter one afternoon. Had to put the petal to the metal to try and get home... Then quit running and won't start at all. Of course it cranks however will not actually run. Replaced the fuel filter. It
ran great for about 300 miles then, it happened again. Replaced the fuel pump and sock. Started up sputtered then quit again and back to the drawing board. Checked fuses, relays and all good. I'm stuck! - Visitor
no power to distributor and would not start - Visitor
