No Spark and EVERYTHING has been checked, HELP!!!! Options

[6G94celica]

These are the readings i got on the 5 pins of 5 the igniter.
White with Blue stripe = 10.9V
Black = 10.5 V
Black with Orange stripe = 10.9v
White = 12 mV
Black with Yellow stripe = 557mV

The readings i got from the two coil wires were as follows.
Black with Orange Stripe = 10.9V
White with Blue Stripe = 0V

I did these tests with the key On but the car not running.

All those seem to be correct based on what I remember when I was trouble shooting mine... however, there is something that sticks out. You should be getting 12v and not 10.9. Thats too low of a voltage to start the car. Have you checked your battery and alternator? It sounds like thats whats going on here. Especially since the car was already running with the swap at one point.

Most distributor and ingiter problems would also throw a CEL. Its actually the only part of the efi system that the stock ecu is really good at diagnosing.

ya my battery is a brand new optima red top but alternator could deffinetaly be bad. ill look into that.

Anyways update with even more bad news. Cylinders 1,2, and 4 are dead. they dont even flicker the compression test. cylinder three jumps around. it will sometimes read 155 and sometimes only a mere 55. this sounds like my timing jumped. if my timing had jumped would that effect the spark at all. could this be a possibility of why i have no spark. Also ive read this before but dont remember, are the 3sgte motors a 0 tollerance motor or no. could any of my valves possibly been bent.

All of this sounds like a new battery that got killed by a dying alternator.
You need to have a perfectly fresh charged battery to do a compression test. Since yours is only sitting at 10v, it doesnt have enough power to even perform an accurate compression test.

Swap out the battery with a fresh one from another car, and try to start it.

well now all i need to know is whether or not i have to rip the head off. my timing belt broke so do i need to worry about any of the valves or anything else being bent or broken. from what i remeber when i tore the motor apart the piston wouldnt hit the valve am i correct.

Wait... who said your timing belt broke? How do you know that happened?
The 3s is a none interference engine. Even if the belt goes, nothing will get damaged.

[6G94celica]

ok thats what i was looking for. i just pulled off the timing belt cover and there she was split in 2. does the HKS timing belt for a 1990-1995 turbo mr2 work on the all-trac 3sgte or is the teeth count different.

[6G94celica]

anyone know if the mr2 turbo timing belt will fit the celica all-trac

[lagos]

yes, since its the same motor.
but its total over kill. all you need is a new stock timing belt.

[6G94celica]

ok just checking im gonna get the new timing belt this week and ill update you on how it goes.

[6G94celica]

so the new timing belt is in and everything is back together. i tried to start the car and it fires once and then just turns over. it sounds like a timing issue but i rechecked everything and its all fine. i just got in my nology hotwires and nology silver spark plugs. my cap and rotor are fairly well worn but it ran before just fine on them. it seems to be getting fuel but lacking in spark so that is the only thing i can come up with. my battery is a little dead but i hooked a charger up to it and cranked it over on engine start with 12-13 volts to the coil. if anyone has any ideas other than cap and rotor let me know. thanks alot

Hey guys i think have a similar issue as 6g84celica...... i own a 5sfte... after i finish servicing my car.. took it for a run down the road... everything was good. then when i went for second run... about 80km (in Australia).. the car just died out... like it just stop... i tried looking for and looses wire or unplug cap from the distributor and ignition side they were all good.. but when i turn the key to start it, the starter activates but the car just wont start or fire up... i check my battery, starter, distributor, ignition and alternator.. they were all fine... the only thing i havent check is the timing belt...

do you guys think that its my timing belt to?
god help us...

[6G94celica]

sounds like it. thats what my problem was but take a multimeter and check for voltage to your coil and check the main ground bolted to the bottomside of the intake. also try to run a diagnostic test on your ecu to check for codes. its not hard to pop off the top timing belt cover though so you mise well check that right away. good luck

[xxFROZENxx]

yeah my timing belts fine..... so now i need check for voltage to my coil and main ground bolted..
