ok so this would be the 4th thread i have posted i think, and im pretty sure u guys are sick of reading my posted but i have tried everything and this car wont start. Here is a small list of the things i have tried.and replaced
new fuel pump
new injectors
new fuel tank
new battier
new hoses all around
fuel pump switch
new mass air flow meter
i even rebuilt the old on
new ecu
new coils leading and trailing
i have put the car in time.
i have changed the oil
new shifter
i have unflooded the car over 10 times
i have pull started it and nothing happens.
it used to run what went wrong?
and yes the coils are very strong.

 

how about your harness?
might be some electrical problems..

 

ok that could be very possible but before when the car ran it would not keep an idle unless i kept the idle steady.
so i highly doubt its my harness. but ill give it a check but if u have any more ideas please tell me i want every piece of advice i can get.

 

Ok lets start from the beginning?

Does the car have spark from the spark plug's?

If so verify the injector's are firing by applying power to them while they are out of the car there is a way to do it but i cant remember where i read it right now.

Have you ever made sure your injector's are firing?

 

I would double check all the connections. I forgot one plug hookup from my engine harness to the body and i had no power to anything

 

"Pull start" is that like push starting and popping the clutch? and no workie....check all fuses in and out of the car, ignition switch where the key goes...

 

Mate, have you checked the compression, honestly with all the stuff you have looked at or replaced it must be the only thing left..but I would have thought that even this being the case you would be able to pull start it....

 

Is it possible that it is REALLY REALLY flooded? Mine was hidiously flooded a while ago and nothing, not even push starting would work.

I did this http://rx7.com/techarticles_unfloodFC.html

Note i used motor oil instead of ATF. worked great and fired right up. quite a bit of smoke but hell after three days and alot of batt charing it worked great!

give it a shot as it cant hurt.

well i know its not the compressing because a rotary mechanic had checked it for me before i bought the car and he told me it had perfect compression the other weird thing is this car only has 82,000 miles on it.
oh and i have unflooded the car before i go to pull start it and it didnt make one difference not even a sputter.
also not to long ago before i got my new injectors the car sat up but before the car sat up i changed the oil and the other day when me and my military friend check it the oil was really milky like a light light brow, not the color it should be.
and im positively sure im getting spark because i took one spark plug out and put a nail in the socket and it arched all the way down the nail and the other sparked to.
and i will check the rest of my harness but is it possible its so far out of time?
oh and is there supposed to be oil and gas on the spark plug when u pull them out???

 

Alright here's what you do:
Check the compression numbers yourself. You can do this and should provide you with good amount of information about the condition of your engine.

Next check your coolant level. Is it staying full or is it disappearing? Does your coolant look... Milky? Might be a huge indicator if it does.

You've confirmed spark. Have you confirmed fuel pressure? Use a fuel pressure gauge or use the FSM procedure to make sure you're getting good atomization. Check for rather large vac leaks--this may not play a part in the start procedure, but later down the line if you have an exceptionally rough idle could resolve that problem.

Next make sure you have your TPS set correctly!, 1 volt reference signal. Check the forums for how to do that.

If and after you've done all those and they've checked out. Attempt to crank it over. If you have a friend have him crank it over while you listen to the pulses in the exhaust, what do they sound like?

You may have a clogged exhaust and the simplest way to check is actually to just remove the cats and crank it. It'll be loud, but you should at least verify that you have no blockage in the cats.

Once you've done that, come back and report.

...also, how can you set the timing if the engine isn't running? something smells fishy to me...

 

ok so i just finally got a hold of my rotary mechanic and i told him whats going on aparently i have a blown colant seal. and i thought u could set the timing by pulling out the crank angle sensor then rotating the engine.

 

Check your coolant before automatically assuming it's a blown coolant seal. Could be a range of things. You changed your oil on a humid day, engine cooled down and condensation built up and mixed with the oil. You have an oil leak somewhere and drove through a puddle which threw some water in the lube. You poured oil in the rain. Could be a range of things, but check your coolant. If it's disappearing and you've eliminated the Cold start system (which you should have done already) then your coolant is, dun dun dun, mixing with your oil and it's time for a rebuild. No --Ted

 

Yeah, I saw that you unflooded it like 10 times. Me too. But when its really flooded bad, you need to go that extra step, the gas messes up the seals by washing away the oil, and you lose compression. If you try unflooding it without the oil when its this bad you will never get it started. Like i said I tryed to push start mine when it was that bad and it wouldn't go either. After the oil it worked fine.

Give it a try it'll take you like 30 mins and if it doesn't work you can rule out one more thing.

 

dude im so ******* confused.
i didnt try the last post some one posted because im scared to blow a seal or lose compression
but the main thing is i keep asking other rotary mechanics the same questions and i get a diff answer all the time. now some ones telling me i got a bad ground wire thats why the tac wont move when i pull start it or anything..

 

If your Trailing Plugs are Fouled,Or your Trailing COIL is Bad,then you won't get any reading off the Tach.it Relies on the Trailing coil Spark to get signal..if it doesn't see Spark,either from a Bad coil,or from a Fouled up plug(Severely Flooded Engine will Foul up plugs,hence no Spark) then the tach Won't work.
