Topic: Bad Igniter?

[brockbuilt85]

So i picked up an 88 2wd pickup carburated, and im not getting spark out of it all the time. when i turn the key over to "ON" no spark, when i crank it over, nothing, but when i turn it to off, i get one good size spark. i replaced the coil with one i knew worked and same thing. when i turn the ignition to on, i get power on the positive side of the plug going into the igniter. anyone have any ideas that might lead me away from the $300+ dollar fix, maybe some other thing i can test?
Thanks in advance!

i ran into this same problem in a ford bronco with a 351 modified it turned out to be a wireing issue somewhere it took us for ever to figure it out a wire was freyed and grounding out

there is a toyota sticker on the side, in bigger font it reads
375 but in smaller numbers its 89620-35140
those were all the numbers i saw on it, they were on the side not on the top, there was nothing on the top

bummer! thanks for looking tho!

[yotaneck13]

yep not a prob ill keep ya in mind at the scrap yards tho

[brockbuilt85 [OP]]

ok, so i found another igniter, looks the same, numbers are different. hook it up, has spark, has gas, tries to start but sputters and coughs, wont start. is the igniter still the problem as its not the exact same one? or do i have another problem? we have adjusted the timing like crazy, but same result. its got a weber carb and it has plenty of gas....
thanks in advance for your help guys

[yotaneck13]

im betting it is since they are not the same it could be giving you the wrong spark and what not i may have found the right one tho pause and ill re check it monday night

anyone else have an insight to this?
