Well, I have been sitting on my B16a1 project for the past few months and am now getting ready to start it again. The problems I have been having I am sure are electrical. The car turns over but will not fire. I have replaced the dizzy and checked the timing which as far as I can tell is right. Some of my VTEC wires are not hooked up but that should not keep it from starting as far as I know. Next I am thinking about taking my wiring harness out and putting a new one in then totaly rewire everything. If you have ideas of suggestions please let me know. Thanks.

Ok heres the deal. I am doing a JDM B16a1 into a 90 CRX Si. I have everything in. I have the fuel lines hooked up. I have the ecu pinned the way I was told to pin it. I have odb0 everything and the car will not start. I had a leak in my fuel pressure regulator to I changed that out. I had a 1/4 tank of gas that was sorta old. So I drained it and refilled it. As far as I can tell everything that needs to be hooked up is. The VTEC pressure switch, the VTEC oil wired, knock sensor. I have the O2 sensor wired in the ECU but not connected in the engine bay because the plugs do not match. One of the other things I have had to do was switch the motor to obd0. It is an obd1 motor so I went and got a proper dizzy and was told that would be it to make it obdo. So the long and the short of it is I have everything wired but the o2 sensor and all the car does is turn over and will not fire also the fuel pump will not stop priming. I cannot figure out this last one. There are no leaks there is fuel. If anyone has any ideas please let me know. I need to get this thing working as I need it for college in January.

Cliff notes. B16a1, was obd1 now obd0, everything connected will not fire. Fuel pump will not shut stop priming.

Here is some back ground info.

 

Here is some more info on the project.

I have just put in a B16a1 in my 91 CRX Si and the darn thing will not start. What is the firing order and what plugs go where on the distributor? Where can I get a new dizzy if I need it? It seems like the motor came out of a Integra XSi 92-93 model if that helps. I am pretty sure I have the firing order right but I would like it if someone could confirm it for me. If it is the fuel pump what can i do to fix that? Sorry to seem like an idiot but the fact of tha matter is I have been a american iron dude until lately. All my experiance is with carburators and 5 plus liters. Thank you for any help you can give.

the top right side of the rounded side of the distributor cap is the number one plug wire. going clockwise from there it is 1-3-4-2. The order on the valve cover is 4-3-2-1, and one is the furthest to the right on the valvecover. Check your grounds especially the thermostat, valve cover, and tranny grounds. Make sure when you turn the key to "on", the ecu blinks once to show it has power and doesn't blink anymore after that. If it does, check your codes.

 

are you getting spark?

smell fuel in the cylanders?

start with the basics..

 

Have spark, fuel, and the grounds as far as i know are good. What does the tranny ground look like? I have a ground hooked up to the tranny but I am not sure its the right one. Thanks for the input.

 

it's the other end of the negative cable on the battery. It is held near the clutch cable, by a 10mm bolt.

 

if you have fuel and spark, then check both your cam timing and ignition timing. A compression test will tell you if your cam timing is dead on or not.

I have timing, spark and fuel. I suppose I will check the comp. next time I am at home. Any tips on how to do this myself?

 

compression tester, the kind that just screws into your spark plug threads. just crank the car over an even number of times for each cylinder, like 5-6 times.

no check engine lights? does the check engine light come on at all? the ecu isn't flashing?

 

When I first turn the key i get a red light from the ECU but it only blinks and then comes on. I have only gotten check engein once or twice for about 5 seconds if that. Not sure what to make of that. I am going to have to wait til I get home for the summer to do anything though. I just do not have the time one the weekends to do anything.

 

Bump.

 

hey i'm having the same problem your having and i was wondering if you found out anything. Please send me anything you can possibly tell me.

Thank you

 

how many times does the red light blink on the ecu when you turn the key into the ON position. Count the blinks and pauses.

 

try a different ecu, u can even try your stock sohc ecu just to try it out. i had this happen on a customers car before and the red led on the ecu would just stay on and car would not start, try that.

 

Well I have tried a different ECU, the stock one and it did nothing for the car. Also as far as the red light goes all it does is blink once realy quick when I first turn the key and then it goes out and stays out. Is it possible that the only thing wrong would be the starter? i feel dumb asking but maybe I am over thinking it.

 

does the motor turn over? if it does its not the starter.... did you use the stock harness? there really isnt any thing to de pin etc. only add vtec press, vtec sol, and knock.. did the car start beforee the swap?

-joseph

 

yes, the car did start before the swap when I had the d16 in. Also yes the car does turn over... So I have no idea what to do. The stock wiring harness is in there and the ECu is pinned. Let me know if you all have any ideas.

all you did is add wire correct?

to start a b16 you dont need to re pin any wires any wires

if so id go with the timing
