I did a obd0 d16z6 swap on my STD hatch. I rechecked all my MPFI swap wires, grounds,changed the main relay, changed to another Pm6 ecu, changed resistor boxes, everything that I could possibly double check. The car is getting spark, and I can smell fuel on the plugs. But, the car will not crank at all.

I also did a compression check its 160 150 119 90. Can the compression be the problem? Please give me any ideas that you can think of. I really need the car started my Sun. Any help is appreciated. TIA.

 

sure the battery is charged? (sounds stupid but you never know)

Is the motor getting fuel?

And is the motor timed?

 

did you by chance put the rotor on the dist. backwards? on a rotor i got from autozone it had a hole drilled all the way through where you screw the rotor down, and i put it on backwards. i assume you guys rechecked the wiring and it was good? have you checked timing with a timing light? it sounds so much like timing with fuel and spark. any codes?

 

I rechecked the dizzy,wiring,timing and everything is right. Im not getting a fuel, because it cranks when I spray brake cleaner in the manifold. And im throwing a code 10. Im going crazy right now, its been 2 weeks without my car.

 

code 10 is your iat sensor. if you've narrowed it down to fuel than you just need to find out where. what fuel line did you use from filter to rail? what intake are you using? there are two typres of fuel rail nozzles and each requires a corrosponding fuel line. on the 4th gen rail, fuel comes out the end, and on the z6 rail, fuel comes out the side. it could be the filter? do you hear the pump prime when the key is switched on?

The compression is not the problem. I had a motor with 150 150 150 90 and it ran for months STRONG, you gotta remember too, that the compression will be low cause the motor has probably sat for a while and hasnt been warmed, when you check compression your suppossed to do it on a warm motor..

Now.. Your getting spark, fuel, and you have compression. Only thing it can be is timing... You cant be off too much on the distributor where it wont start, honda was smart, made it dummy proof pretty much, lol. But if you messed with the timing belt, I would DEFINITELY check the timing belt, make sure its in time.

Have you checked the injector pulse? If you havent, get some noid lights or a test light, ground it, and put it in the power side of the injector clip, make sure your getting 12v to the injector, if not then its in your injector wiring. Because you have fuel pressure does not mean its injecting into the motor. Check for injector pulse, if you have that, check your timing.

 

Im using either the 88-89 teg or crx si fuel line they both look the same and I have both just dont remember witch one (fuel filter to manifold). Ive compared it to the 88-89 teg,88-91 crx/civic and my STD ones they all look the same. Is there any difference internal? since exterior hoses look the same.

I do believe that im not getting any fuel in the motor, because it cranked when brake cleaner was sprayed into the intake manifold. But the wierd thing is when I pulled the fuel line (fuel filter to IM) to change the washer there was fuel there, but I guess its not going through the injectors. I've checked the injectors with a test light and all 4 is coming on. Timing is on point. Im going to try new injectors.

 

if you have the z6 fuel rail, it's hole where the fuel enters the rail is on the side of the threaded stud sticking out of the end of the fuel rail. the 4th gen fuel rails lets fuel enter throught the end of the threaded stud. when i originally did my mpfi swap we had to modify my std fuel line with a dremel to get it to let gas flow. it also used a different nut to hold the line on. the std fuel line will go on the z6 rail but it has to be modified to go on the a6 fuel rail. i'll try to get some pics up.

this is the z6 rail

this is the a6 rail

 

Now that I thought about it. Im using my old STD fuel line. Is that a bad combo with my A6 intake manifold/fuel rail?

 

yes. what i did was dremel out one side of the banjo bolt to allow fuel to get to the hole on the end. i eventually just modified an obd1 fuel rail to fit my intake manifold. you either need to modify the banjo bolt or use the z6 intake manifold. the std line also requires the special nut for that type of rail. i'll get more pics later.
