My spark plugs are not getting spark. I changed the whole distributor ( coral, ignition module) etc. it's not the fuel, it's not the air. It's not the timing belt or compression, it's not the ecu or any fuses, it's not a fuel pump, it's not the crankshaft or cam sensor. I put a test light on everything and it seems to not be getting power from my rotor or distribur and there both new. Someone please help! I know quite a bit about cars and never experienced anything like this! It's not out of time either my timing belt is fine

Ok this is strange to me, when I turn my key over my engine light is very dim, the rest of the lights are fine. If I unplug my main relay my engine light is bright like normally. And for some reason my car won't allow me to retrieve codes

Ok, so my car wasn't starting for a few days and I went through soooo many things to try and diagnose it. My car was not reading any codes from the machine when they hooked it up, it won't start obviously I'm not getting any spark at all. So I had a wire loose called a g101 ground which connects to the housing of my thermostat which was loose which grounds for my ecu and main relay, pretty much the electrical system. Can that ground cause my ecu board to short out and cause the machine not to pick up any codes on my car?

Also, will a obd2a p2n work with a obd2a p2p???

What ecu computer board will work for a 97 honda civic ex 5 speed engine

Where are the fuse links located on my car? There are fuses located on the harness I just don't know where there located

Ok I have literally tried everything to get my car to start I have a 97 civic Dx with a honda ex swap. I have a ground wire (g101) located on the thermostat housing which was loose and I was unaware. My car wouldn't start so I end up changing my fuel filter my entire distributor and everything in it Etc. So new coil, module, etc. My car only turns over but will not start for nothing! Once I found the ground I cleaned and reconnect it and I was wondering if it blew something? Also I jacked my car and found that the sensor from my crankshaft is getting chewed up by the alternator belt and if that can cause it?

coral? do you mean coil? check this out.

Check out the service manual, it has step by step troubleshooting instructions.

If you don't have spark at the plugs, check back at each step of the ignition system. Check the coil for spark (use a large screwdriver).

I ran into this problem before. My car died on the highway. I got it back home and no spark at the plugs. I replaced the wires/plugs, ignition module, coil, and eventually the entire distributor.

Still no spark!!!

Then I got smart, tested the coil for spark. Bingo. Had spark at the coil. You know what that means? Cap/rotor is bad, and it was. New distributors don't come with cap/rotor generally.

Yes I meant coil my apologies.... But I got the whole distributor today. I tested my coil and it's getting spark and my igniter is getting spark as well. The cap and rotor was used and that's where I'm not getting spark from. I was afraid it may have jumped time but that doesn't sound right. I have literally checked everything on my car there is even the main relay and everything seems fine.

When I did get the distributor it was all assembled and all I did was bolt it on and it still didn't start

sounds like you need a cap/rotor then.

cbaber

Ok great if you have spark at the coil, then you KNOW the problem is cap/rotor and beyond. So since your cap/rotor is used, replace it with a new one. Take the distributor and get your money back.

Kt18777

Okie changed the rotor and distributor and still no spark coming from them. It's the strangest thing I ever experienced in my life! It's got me so confused. I'm still getting spark from coil but not my rotor which is so weird! And strangely my cel is very dim, but if I disconnect the main relay it's bright! And I tried to stick the machine in today to see if there is any codes and it wouldn't retrieve any, it kept saying check connection cause it would not pick up anything

cbaber

Did you change just the rotor? You need the cap as well. Also, make sure you are matching the right distributor. TEC and Hitachi are different, they have different cap/rotors.

If you didn't replace the distributor cap, then that is your problem if you are getting spark at the coil. Either that or the wires/plugs.

Kt18777

I changed the cap and the rotor and still nothing. Both are tec brand and all the engine is doing is turning over still.

How do you know you aren't getting spark? Are you using an HEI/DEI tester?

cbaber

Well if there is spark at the coil, the only things from the coil to the plugs are the rotor, cap, and wires so somewhere in there is your answer. Make sure the timing is set correctly. Rotate the engine to TDC and verify the cam gear and crank pulley are correctly aligned.

Kt18777

Amazingly I found the problem. There is a ground wire (g101 ground) that is grounded to the thermostat housing. This whole time I may have replaced everything for a loose ground wire

Kt18777

I need the right way to time my distributor right to get the correct firing order. I just replaced it it it's not cranking cause I am certain it's not timed right.

No offense, but you aren't the first to ask this question. In fact, there is a section titled Frequently Asked Questions (FAQ) at the beginning of the forum. I bet in those FAQs there is an answer to your specific question...

Ignition Timing


Put in the effort.

Ok, the other morning I checked my thermostat housing to see if it had a thermostat in it cause my temperture guage was messing up and it didn't have one like I suspected. After I checked it my car wouldn't start. So I assumed it was fuel related so I changed my fuel filter cause my pump is fine. I'm getting fuel just fine it wasn't my issue. So I wasn't getting spark so eventually I end up changed thee entire distributor ! It still wouldn't start, so when I ran the machine on there it wouldn't read codes, so I'm like wtf! I did some research and comes to find out on my thermostat housing there is a main ground wire (g101) that grounds the main relay and ecu and it was loose which was my problem the entire time! So now that works perfectly fine and some reason I'm still not getting spark to my wires. The entire distributor is new, the cap, rotor, coil, ignition mogule, and I'm not getting spark to my distributor but everything inside my cap is getting plenty on spark... Someone please help

What motor? Any mods or all stock?

Kt18777

No mods at all except a cold air intake. It's a d16y8 5 speed

TomCat39

Any non OEM parts?

Maybe you got a new but faulty rotor or cap or both. It's rare but can happen, especially with non OEM parts.

I'm assuming you've done the proper coil tests and the proper ignition module tests and they all tested good.

B_Swapped93

no but try another ECU if you can.

Kt18777

You mean the whole ecu computer box right?

i have a obd2a y7 p2e and a obd2a y8 p2p each for 30 bucks plus shipping (should be 5-10 bucks for 3-5weekday shipping) if youre interested

Kt18777

What kind of ecu will work in my car? It's a 5 speed ex

BTW, its a P2P if you're somehow still lost. Neither of the ones that that guy was offering you in your other thread has VTEC from what I can tell.
