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

[6G94celica]

So the car ran and drove fine for a couple days and then i was about to put it in my garage and it died. it didnt really sputter as if it was out of gas just suddenly stopped. i checked for spark and there is none. the coil has power but there is no power at any of the pins on the distributor which leads me to believe something in the wiring is bad or the ecu is fried somehow and power is not sent to the distributor to inturn send signal to the coil. i checked with a timing light to see if there was power through the wire from coil to distributor and there was none. so the coil is maybe bad but it might just not be getting the signal from the distributor. im extremely pissed about it all because i just got it running.

Also on another note did anyone else have a problem closing there hood after completing a swap. for some reason my hood is not able to close past the first latch. i think it is hitting my radiator but it is the stock radiator in the stock location so i dont understand why that would cause a problem. again any input is appreciated. thanks alot

Bump c'mon someones gotta have ideas

I am assuming this is a swapped Celica? Cheapest and easiest test is to go get a MSD Blaster 2 (?) Coil from you favorite auto parts store... If you get good 12V to the Coil and it is properly grounded, and you are not getting spark and you are comfortable it is not the distributor... try this first...

[stephen_lee]

who did your wiring?

[6G94celica]

tweak did the wiring

[stephen_lee]

i think distributor is just hal sensors. so you wouldnt have power to them anyway. are the coils the ame for the 3s and 5s?

[6G94celica]

im not sure, i got ahold of tweak and im gonna try a new igniter and an MSD coil. im leaning towards the MSD blaster 2. any toehr ideas for the coil.

[alltracman78]

Have you made sure your timing belt didn't break or jump time?
Pull off the dist cap and make sure the rotor is turning when you crank the engine.

Hall effect sensors do require power to work.
Less than 12V, but power none the less.
Regardless, Toyota doesn't use them in their dist, they use an inductive pickup.

ah got them confused somehow. anyway inductive pickup doesnt require power, does it?

[6G94celica]

yes the rotor is turning so the timing belt is fine and if the belt just jumped there would still be spark, the car just wouldnt start.

[stephen_lee]

are you getting fuel?
if you are, the ecu could be ruled out as a possibility.
the black wire w/ orange strip should have +12 when the key is on.

[6G94celica]

the wire on one of the ecu plugs or the fuel pump. i havent had time to run out and do this yet but i did jump +B to Fp and the pump kicked in but even cranking i dont here the pump running unless jumped

[trd-celica]

have you check the alternator,battery or starter

[6G94celica]

have you check the alternator,battery or starter

yes sir all good

[6G94celica]

so after a new igniter, coil, ecu checked and rechecked a million times, the wires going to coil checked for resistance, and all the grounds checked and tightened, it still wont fire, there is no spark and sounds like there is minimal compression. ive been talking to dr. tweak and hes stumped as am i. any help from anyone would be greatly appreciated, just throw stuff out ill let you know if ive checked it or not.

[6G94celica]

come on someone has to have some ideas

[lagos]

1. Did you ever check for codes (regardless if your CEL is on or not) ?
2. Did you check the voltages at the different pins on the igniter and coil and compare them to results from a running car?

[SlickRick]

sounds like its your ignition box, since u can not dynamically test it, that must be it. It will show up fine when u check with everything off. Try just swapping the box.

i have ran codes and none show up, as far as checking the pins i have no way of doing that unless i can get a list of voltages from someone with a 2nd gen swap because unfortunately there is no one in the vicinity of where i live that has one. if someone could provide me with this list it would be greatly appreciated.

as in ignition box do you mean the igniter or am i completely mistaken, the igniter has been replaced and changed nothing

Test them and post up what you get.

[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.

[6G94celica]

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..
