The ignition coil inside the distributor may fail. Our technicians tell us this may result in a hesitation on acceleration, especially when the vehicle is warming up on cold, rainy days. The pickup coils inside the distributor can also fail and cause a no-start condition. There have also been some failures of the radio noise suppressors inside the distributors, which can short out. Our technicians recommend replacing the whole distributor with a complete, genuine Toyota distributor if any of its components fail.

    i have replaced the ignition coil and it still dies and is hard to start what is the cause and effects of this problem and what else do i have to replace.

    My car died. Very hard to start, if it did start at all. Ignition coil appeared to ohm out ok. So I replaced fuel pump. Still a problem, So then the fuel presssure regulator. Still not good. Would cut out, then run ok. Then would not start unless really cranked it. I checked and replaced the throttle postion switch. Ran better, but would cut out. I ohmed out the Ignition coil again. A bit over spec. So I replaced it. It is runnnig good. Except that it is displaying error code 71, egr valve. I try and clean it. Still a nice car I bought brand new in 1994. It has given us great service for many years.

    I just purchased this car a few weeks ago. On my initial test drive(s) the vehicle was always cold and didn't really exhibit the problem- stumble/loss of power on acceleration. I pulled out the distributor last week just to see what I could determine by inspection and checking with an ohm meter. On visual inspection I could find no indications of any obvious problems- looked real good! -I checked the impedance of the coil, and it was within specs -or if off just barely.

    secondary resistance 11,700 Ohms (11.74 kohms)

    primary resistance 1.7 ( *maybe 1.8~1.9)Ohms

    ( * I suspect this reading to be erroneous due to my using a pretty low-quality meter. Probably actually would've measured 2.0 ohms or greater with a quality meter.)

    I took a leap of faith and ordered one off of eBay made by 'Gamma Electric' - American made and cost less than $20- I know, I know, but that is all the market would allow. Today I installed it, checked the pickup coil impedance this time (it was fine) also visually inspected further into the distributor what I could see with the coil removed- all looked good there, too, except some strange waxy buildup on the cam sensor reluctor (?)

    I put the new coil in, put the distributor back in, buckled it all up... and wow am I impressed! -I could tell it was an improvement from the moment I turned the key in the ignition! It always started fine before, but this time (now) it just feels "spunkier" -and the performance is way beyond my expectations!

    Test drive @ 20 miles -no hesitation, no loss of power, really good and strong acceleration from standing stop and WOT high speed pass ... just wanted to keep on accelerating, not a hint of the original problem! -Actually amazed at the ability of that tiny 1.6l motor to respond like this! -I thought the acceleration before was probably about right for an econo-box with such a small engine (that is while cold, before displaying the stumbling) but I'm pleased to report that this little car can flat out s#$t and git! -Runs like a scalded ape!

    I can see that there are many possible problem areas that might arise in the distributor on these, but I'm happy to report that -even though it "ohm'ed out" okay, all it took to fix my little '94 Prizm 1.6l was $20 bucks, an afternoon, and a little faith. (Well, make that prayer and faith. -Sure can't hurt :) )

    I've had trouble starting my car. The times when you would think it should have trouble, it's fine. Then it randomly refuses to start even though there is plenty of cranking power in the battery. It's really a hit and miss situation. The mechanic is guessing it could need a new distributor but so far it has started perfectly for them -- 30+ times while at the shop.

    cranked but no start, changed distributor, car ran ok for a couple miles, then no start, changed distributor assembly again with new, ran for longer but requires another distributor!

    intermittent starting problem, noise suppression deteriorating on AM stations
    Replaced distributor.
