I have a B18A1 swap in my 93 Civic EG Hatch the car will start and run fine when it has been sitting and the motor is not warm. But when I start the car and let it run for a little bit or drive it then turn the key off the car will not start again. I just got done replacing the Ignition Control Module because some people have told me that could be my problem. Still wont start after the car is warm the engine will just crank. The fuel pump kicks on and primes so I dont think it is the main relay. Could use some advice on what the problem might be if anyone can help me.

 

Are you running a tune?

 

I have a chipped ECU with a base map that a guy put on the chip.

 

I think I am actually running to much fuel because when I get up in the higher RPMs it will start to pop like a 2 step till I shift gears. The spark plugs are also a black color when I pull a spark plug after trying to get the car to start also when I look into the cylinder the top of the pistons is all wet with fuel.

 

Do you have spark, is it a "strong" spark?
Are your injectors pulsing, could they be "sticking open"? 94

 

From what I have checked out I have spark I have an MSD ignition with a Blaster SS coil. If my injectors are sticking open how can I tell or know.

 

Is it a strong spark?
If the black "stuff" on plugs looks soft and sooty it could mean over rich air/fuel mix or a weak spark, or is it a wet black?

You can use a noid light... http://www.noidlight.com/how-to-use-a-noid-light/ a multimeter or low current test light to check the injectors. 94

 

Its more of a wet black not real sooty.

 

Do you actually hear the main relay click? I had the same problem on a 94 hatch. My fuel pump would prime and everything but the relay never clicked. I took it to Hondoctors and they replaced the relay and I haven't had any problems since. Just a thought......

 

I cant say that I have heard the main relay click just the pump kick on then off is about all I hear but I guess I will just replace that an see what happens I guess I am running out of options really. Next step is to take it to someone that knows what the heck they are doing.

 

Replacing parts without knowing what the problem is is an expensive way to troubleshoot a problem.

If you are getting fuel into the cylinders, it is a good bet the PGM-FI Main Relay is working.

If you can not hear the clicks of the relay, you can feel them, hold the PGM-FI Main Relay in your hand, turn on the ign., you will hear/feel two (2) "clicks", it may feel like one click as they are very close together, first click is the injector relay, the second click is the fuel pump relay, at the same time you will hear the fuel pump turn on and the CEL will turn on, after a few sec. you will hear/feel the 3rd click, [fuel pump relay turning off] fuel pump will stop and the CEL will go out.

Leave ign. on and check for power at the injectors, [wire that is the same color on all injectors].

If all the above is happening there is nothing wrong with the PGM-FI Main Relay.

Again, how good is the spark??? 94

 

I just checked the main relay and from what I can hear it is clicking so I guess that is working. The spark is a pretty stong spark I just checked that also. So I am lost with what is wrong with it haha

 

coolant temp sensor. do it again, but before you restart warmed up, unplug the sensor.

 

Ok I will try that and see what happens when I unplug the coolant sensor hopefully that works

 

Take it to your tuner.

 

I need to take it to someone thing is I dont know of any tuner around my area. But its not the main relay I also tried unpluging the coolant temp sensor an that didnt help either so I guess my only option is to find someone that can tune it or knows what the heck they are doing

 

yep, you have expended what we can guess at over the net

 

That could be a bug on CRome.

 

I just got over this same problem about 15 mins ago loose ground wire and batt starter connection. was too loose

 

Well I will deffinately take any advice I can get so I will go an check all my grounds and the starter connection

 

Thanks alot for all your help everyone I got the car running it starts everytime now love it. If you were wondering what it was it was the coolant temp sensor so everyone that told me that thanks for all the helpfull advice.

 

Oh the only thing I have a question on now is when I drove it to my buddys house to put the rest of the exhaust on it seemed like it was driving wierd like something was holding the car back seemed kinda slugish. It would rev up but just seemed like it didvt want to go very good any advice on what might be causeing that.

 

You need a tuner now..

 

if it was a stock motor with a stock ecu i'd say timing, but otherwise.. tune

 

Ok thanks guys I figured thats what the problem was but wanted to get an opinion from some of you guys thanks a ton for eveyones help.
