i bought a crx with stock d15b2 dual point injection with a blown head gasket.3 out of 4 cyclinders wer full of coolant(but would still run lol). drained the coolant and got the cyclinders dry. put the new head gasket on and put everything back together. went to start it and it just turns ovr but nver fires up. ive checked everything and cant find a problem. good spark, good compression, gettin fuel and air. the only thing i can find that might cause a problem is the timing is off 1 tooth but it should still run like that? i put a new battery in it cause i thought maybe the spark just wasent srtong enough, that didnt work. replaced the plugs and still the same problem. if anyone has any ideas please let me know cause im stumped! firing order is corect also. new plug wires. new dizzy.

is ur ecu throwing any codes...check all ur grounds even the valve cover one....is your dizzy wired up right....just throwing out possabilities

 

If your timing is off I would correct that first. Even if you get it started it won't run correctly. Also, check your fuses and what trane1 said.

 

all grounds are correct. no blown fuses. dizzy pulg was broken so i replaced that but still same problem. could i have possibally set the timing on the exhaust stroke instead of compression stroke?

 

im having the same problem. might wanna try fixing the timing see if it makes a difference at all.

 

fixed the timing. it is now 100% correct. still nothing. put it 180 out just to make sure and it did the same thing as before. anyone want to buy it lol

your timing was correct before considering you checkd the compression. i would make sure u didint leave anything unpluged. like the coolant temp sensor (done it before) if you leave that unplugged the ecu will believe the coolant temp is at -40 degrees and will flood the cylinders, making it almost impossable to start. check the obvious sensor connections.

 

lol i hooked up my coolant sensor and it said my car was over heating when i turned the key on lol but i didnt care cuz i just wired up my obd2 injectors and clips but it wouldnt start when it wasnt hooked up

 

y would it flood the cyclinders? and flood em with water? that sounds strange

 

and the compression is good. 196-208

 

checked every sensor on the motor and nothing was unpluged all vacc lines r on, nothing unhooked anywer. all fuses r still good. grounds still perfect. good compression, spark, air, fuel. could it b in the ecu? and exactly how do the timing marks line up on the crank pully? i set the piston at tdc and the marks dont seem to line up exactly correct. should i line up the marks or the piston at the top?

 

lol flood it with fuel...cold starts use alot of fuel. if you ever has a car that refuses to warm up it will run ridiculously rich.

To the op....what are you using to set the timing? There's marks on the crank pulley and the cam gear should have an arrow pointing up.

On the single cams I always leave a little slack, if you set it correctly and then set the tensioner it will pull the timing out after you set it.

 

when i sit there cranking on it for a while i do smell fuel. i was starting to think it was a fuel leak but it might just b what yall r talking about. but the coolant temp sensor is pluged in.
and when i set the timing i just pull the belt off the cam gear, line up the marks on the cam pully then ill pull the spark plug drop a screwdriver in2 the cyclinder and put the piston at the top then put the belt back on.

 

there is a big difference between coolant temp sensor and coolant temp sender. the sender (one wire) is for the gauge cluster. the two wire next to it is for the ecu to read the coolants temp. check that. or unplug it and try to start. or jump the two pins on the plug goin to the coolant temp sensor. depending on if its a ntc or ptc sensor. try both

 

Ok I just gotta throw this out here make sure all your grounds are in the correct factory placement. Hondas are very particular about the grounds anyone who's hooked up or not hooked up a ground correctly knows exactly what im talking about. I had a hell of a time with mine when I relocated my battery ended up running wires all the way back to factory grounds.

 

grounds are in factory placement. even the valve cover ground is on

 

well i think that im giving up on this thing so i guess its time to build it. i found a z6 head with everything complete even the intake mani for $100. i have been searching arround and i cant find any info on the d15b2 block with a z6 head. does this set up work?

also i tried all that above and still wont fire up.

How do you know that you are getting good fuel on that setup? Have you checked the pressure at the filter with a fuel pressure gauge?

Have you tried removing the throttle body and making sure that the Oring seal is good. If that's screwed you'll never get it to run.

Have your tried spraying starting fluid down the TB while some1 cranks it to see if it fires? IF you do this and it still doesn't start then your problem is not fuel. It's either timing or ignition.

You did check compression after the new gasket was put on?? You are sure you are getting good spark on all four plugs right?

If you are unsure about the timing on the crank then just slide a pencil of chopstick or whatever you got inside the spark plug hole for #1 and spin the crank until the cylinder is at it's highest point. Also, while you turn the crank you will notice that for a few degrees of crank rotation the piston will not move once at the top of its travel range. You want to make sure that you leave the crank in the middle of this 'dead' range. That will definitely be top dead center.

In other words, once the piston has reach the top of its travel you will be able to spin the crank a few degrees and the piston will not move. If you can turn the crank 3 degrees before it begins to move back down then after the piston has reached the top end of travel, turn the crank 1.5 more degrees in the same direction to ensure TDC.

Where are you located?

 

when your checking spark crank it for a while iv seen some cmp/ckp sensors go bad and it will spark for a few sparks then stop.

 

as far as the fuel goes all i know is that theres fuel on the plugs after i crank it and pulll out the plug. and i nvr pulled the carb off so i dont c any reason y that would b messed up but ill check it. and im located in chatt, tn.

 

also it does have consistant spark. and its blue

 

bump. any other ideas?
