i have a 90 hatch. i have spark, fuel, air, and i can't figure why it won't start there's compression. so i'm asking for your help to figure out my problem if possible. any question needed will be answered. i need my fellow ED's help to get mine running so my cousin and i can go cruise because he just baught his.

so i checked fuel, timing, spark, injectors, so now i don't know what else to check and if this helps i have a y8 in the car. i really need help

 

noone?????

 

A lot of people miss the obvious...
Check main relay?

https://honda-tech.com/zerothread?id=1032246

 

going try that tonight. thanks that didn't even cross my mind

 

How did you test for fuel my friend, if you truely have fuel then the main relay is not the problem, you will need to pick up an adjustable spark tester though, I would look closer at weak spark, IF you have positive fuel flow. What do the spark plugs look like, they could be all black and richened out too much.

 

the grounds on ur car or the ecu.

 

i've check the spark it strong and i know that fuel is getting in because i took ithe injectors out and faced it point up and turned the key to prime and it sprayed . that's how i know that there's fuel. and i check the negatives. so if i'm getting spark then my main relay is fine correct. could i add more ground to the motor to help with the positive spark you think? i'm just stumped.

 

ecu is the only thing i haven't checked, but if the ecu was bad then how would it send signals to the distributor to spark and its sending the signal from the cranks sensor. you know what i mean. so i figured my ecu is good. this really sucks, but i feel like selling it. it took me soo long to find it in such good condition, so i can't part with it. now i just need help from my fellow ed drivers. thanks for replying. really appreciate the help and this is calming me down, by posting and reading the replies

 

are you sure your getting spark on all the wires? your main relay could have taken a crap sure by pulling the injectors out and checking them when you turn the key on but the relay switches back to off and your injectors stop. try a cranking test you should see all the injectors prime that way. Main relays sometimes will click on when you have in position two but when you try to crank it wont make proper contact. check resistance in your wires.

 

yup every wire is getting spark.what's position two you mean when i turn the key? because that's what i did i dind't crank the key so the engine turned. if you thought i did that.

 

yeah exactly there is three positions on the ignition position two primes the fuel system to get ready when you put it in three the cranking stage. When your in position two you only get about 5 seconds of relay contact wich will kick the injectors on but once in position three (cranking) you should see the injectors flow in timing sequence.

 

i didn't wanna crank it with injectors out so i hooked up a light to all four and saw that all of them was turning on in sequences.

 

Oh ok well then you really dont know if your getting fuel thats just telling you that injectors are operating properly so you can rule out the ecm as being your problem . your probably going to have to pull an injector just to check flow or listen to your relay click its two clicks. or do it the ghetto way put starter fluid in the throttle body and if it starts for a bit then no fuel.

 

well i only pulled the injectors out and faced i up when i only turned the key to prime stage 2 but i didn't want to leave the injectors out while cranking be cause i was scared too much pressure would pop the injectors out. you know what i mean. but if it won't shot the injectors out i will do it will cranking.

 

The main relay is fine, you got me thinking about your injector spraying with the key in 2 position, this is supposed to prime the fuel rail, not spray the injector, you need to crank to get ground side control for the injectors from the dizzy TDC sensor. Pull them all out if you can, do they all spray or just that one, I THINK none of them should spray in 2 position, I THINK that this is a leaking injector and now your engine is flooded (one cylinder at least) and wont start, prove me wrong please.

If you have been cranking and cranking then you may have washed down the cylinder walls anyways and lost some compression and now you may need to add some oil to each cylinder and try to start while holding the throttle all the way open, half a cap should be enough engine oil per cylinder.

 

Injectors do open shortly in priming routing to allow gas in combustion chamber for easier start up. Highly doubt you'll flood the motor as its not as easy to flood like a carburated vehicle. if it does "flood" it will start but misfire. and if your going to check cranking status on vehicle make sure you have someone to help you hold the injectors in because they will pop off. like i said just spray some start fluid or poor a little gas in intake to see if it starts it can only be one of three fuel air and spark.

 

ummmm did you make sure all your wires are plugged in? cuzz like my hatch it did the same thing and i had to double check the wires and found out the started wire wasnt connected and then the fuel line wasnt connected either

 

those are connected. if the starter wire wasn't connected, the engine wouldn't crank over right? just a question. and fuel line is fine. but i will double check after i get out of work.

right...

 

alright guess checked everything that you guys suggested. everything is connected. and the relay works because i took mine off and put it on my cousins hatch. any more suggestions?

 

I was having the same problem with my HB just the other day I was getting fuel, had compression and using a test light for the plug wires I was getting a signal.

The short answer for my problem was a bad coil. It worked but wasn't sending out enough power to jump the plugs under pressure but enough to set off my test light.

What I found out from an old friend of mine was that he use to test plugs in a compression box. You screw the plug into the box, pressure it and then see if the spark will jump the gap.

Little disappointed in my test light. Would be nice if it didn't work unless there was enough volts going through it.

Here is a link to my post:

check your timing! might be 180* off. and check your fuel pressure.

but if you have fuel, spark, and compression then it should start. it seems to me that it must be a timing issue. the plugs might be firing but that dont mean **** if its firing at the wrong time.

 

did u check the starter? idk if thats been said yet or not. i had a similar problem with my car it turned out to be my dizzy. (distributor). but any autozone or parts store should be able to test ur starter.

 

and the guy before me is right too... ive had a timing issue once before also.

i dont think cranking is his issue, and he said he tested for spark and he has spark. so that rules that out. i say its the timing. take out your distributor. move your motor to TDC of the compression stroke on the #1 cylinder. and reinstall the distributor with the rotor pointing on the #1 plug.
