d15b7 would crank but no start

- Tue Apr 29, 2014 8:16 pm #345166 Other day, It starting to act weird. That night when I drove my car down the road, everything is okay,no cel. BAM! It shutted itself down and has lights on, had to turn them off as I am rolling and pulling over. I tried again to start, it would cranking but wouldn't start. I popped open my hood and looked around my engine. Like I have no idea.......... then I went in to see if I got any cel, none. I tried again and started them up, it running fine then drove for another half hour to arrive at friends apt. I shoring on my car to park in neutral, it shutted down again. So I thought I should chill at apt then leave, no start, nothing.

Today, I checked it with spark plug tester, it shown light then after few crank, no more lights. Tried again and does same. I thought it was ignition module so I went to junkyard to find a low mileage civic and found one looks new. Replaced it and it doesn't started at all.

Problem is - ignition switch? Spark wire?

Im lost here I researched it in different site and gotten confused, I don't want to waste my money on new parts that wouldn't get it work.

In my experience, a bad ignition module aka ICM won't give any spark at all. A bad coil can still give spark but then quits when it gets hot.

Me and my friend worked on my car this morning and went to autozone to buy a distributor to see if it works. Back to my car, doesn't starts at all. So I decided to loosen my fuel filter bolt and went to start my car as my friend watch my fuel filter. It doesn't squirt, not even a bit. so I thinks it is the fuel pump failure since engine needed gas to start.

Any thoughts?

- Thu May 01, 2014 7:06 pm #345227 Put your ear on the back seat bottom and listen for the fuel pump prime when turning the key to the acc position. If you don't hear it, it may be your main relay. The main relay should make a click when turning the key. It is located under the drivers side dash.

So does it get spark now after replacing the dizzy?

So you saying it possible failure main relay, I should try to to replace it before I replace my fuel pump.

- Fri May 02, 2014 2:14 am #345245 Have someone listen just in case it isn't bad. That way you don't just throw new parts at the car & waste $ on a new one. Main relay goes bad more often than the fuel pump.

So the car is getting spark now with the new dizzy?

It's not uncommon for the main relay to start acting up when the weather gets warm.

- Mon May 05, 2014 6:10 pm #345314 So none of the cylinders getting spark?, remove the distributor cap and have a look to the rotor ,maybe is melted or some like that and check the cap as well. Could be the ignition coil like teal said.


P.s. Do you have immobiliser?

- Tue May 06, 2014 3:01 am #345327 None of these cyc getting sparks.

I doubt about immobiliser in my car, I bought it from an elderly lady, lol.

I just took time to research on the other site and posted on fb group.
They mentioned about ground connection, it was needed to be resurfaced, clean, and tight.

Any thought of it? I'll try that.

Here is the main relay: Image
