hey..

95 hatchback
d15b7

I was having trouble with the car recently (thought it was distributor)... The car wouldn't start after putting that on. So, I get it towed to a garage that I usually go to.

They've had it now for 2 days. They told me yesterday the problem was the ECU and that it wasn't grounding to the injectors, dizzy (I forget for sure about the dizzy), and maybe something else... Anyway, they figured that was the problem.

I brought them a junkyard ECU this morning, and apparently the car still isn't functioning.

Any suggestions on what it could be? Maybe the second ECU is bad?? Any other suggestions?

Find a new mechanic.

1) Does the starter crank the engine but it won't start?
2) Does the fuel pump prime?
3) Is there spark at the plugs? If not, did the timing belt snap?
4) Any CEL codes?

check for grounds most common problem.. check if the head has a ground, tranny has a ground, and the thermostat has a ground to it too

on the new mechanic bit: way ahead of you on that one.. This garage has always been good, but it seems they can't keep a mechanic anymore... the ones I always trusted are gone...

Items 1-3 I believe so... I'm pretty sure the timing belt is fine.. I'll pop the hood when I see it again..

No CEL's... the only CEL I had before was 9, and I replaced the dizzy...

Before they had no injector pulse.. That is cleared up (wire was just out a bit)..

I spoke with another guy who knows a lot of civics today, and he said to check the ground by the thermostat (apparently that grounds ecu, injectors, etc)..

So I've got a couple minutes tonight and I'm going to get some sand paper and clean up the ground on the thermostat..

Honestly I think it's a ground issue... we have spark (pulled the wires and saw spark), we have fuel (pressure on the rail of 40 lbs, injectors are now pulsing)...

I'll try that ground and see if that helps... ordered some new plug wires too...

If you have spark and fuel, then the thermostat ground is fine. Check whether the timing belt skipped a tooth.

Pulled the timing cover.. The first picture shows how much slack there was in the belt... didn't seem like much... wasn't REALLY tight, but didn't have a ton of slack in it either...

We cranked the car until the "up" mark was on top.... The belt didn't show any signs of having skipped... Unless somehow it jumped a tooth and went back on perfectly... I don't know the likelihood of that though.

We put some new plug wires on, spark plugs had been put in by the garage. We took the dizzy off to see if something had been done incorrectly, but that seems that it was on how it was supposed to be.

We pulled plug wires again, getting spark. We are getting injector pulse, and 40lbs of fuel at the rail...

I'm really at a loss on this. Now the one thing I just realized is that I didn't check the crank for TDC. The cam pulley was at TDC. Is it possible that two would be off one another? If so, that might explain the issue.

Input is appreciated. thanks.

You must check whether the cam and crank are synchronized at TDC1.

update:

I went back to check and see if the cam & crank were TDC.. .As I was working on my car, the mechanic that used to work on my car at that same garage drove by. He and his buddy gave me a hand for about an hour. We are getting spark (as noted previously), but magically when we pulled the screw out of the top of the fuel filter, no fuel was getting there. He had an amp meter with him, and we figured out the fuel pump was getting no power.

Considering the rail was getting "40lbs of fuel" last week, I really don't trust what is happening. I realize that perhaps funny things happen sometimes with a car, but I don't know if these guys are trying to take me for a ride, have no sweet clue, or the car is genuinely just giving them a hard time.

I didn't have any wire last night so we couldn't try and splice into a power source. If they don't have it up and going today, I'm going to tell them to stop work on it. I'll get my old mechanic (whose number I now have) to come and give me a hand.. At least that way I would know exactly what's going on. I'd rather pay him and know what's going on than pay someone else that I don't trust.

Hopefully once the fuel pump is powered, it will fire.

Check whether fuse 24 is blown and resolder the main relay.

what is fuse 24?

95civhb

got it...

update: car is now working. The garage doesn't having a timing gun, so I'll have to get the timing worked out at a later date. Going to talk to the mechanic and see what they did to get it going (hopefully today).

Old post but what was the problem im having the exact same problem except im getting fuel and fire the timing is perfect set it my self fuses are good main relay is good ecu is good grounds are good its all good.

iv worked on hondas for a while but this one has got me stumped. I have 2 hatches and pulled and swapped all the parts and all the parts of the non running car still start the "good running car" and all the known good parts of the good running car still wont start the none running car.

its the same d15b7 242xxx miles

O and the ecu both are good and NO CEL CODES

LMK please i just bought this bone stock car from a 1 owner familey since 92 so i assure you its never been touched

o and i put a new fuel pump on it because it was bad lol

Are the plug wires in the correct firing order on the cap? Does the engine start with starter fluid? Do the injectors spray fuel when cranking the engine?
