Resolved 2G Engine Rebuild

[RubyEclipse]

Hello everyone! I just purchased my 1996 Eclipse GST a few months ago, had some issues with a few different things. Most recent was car was smoking and running very uneasy, so I decided to pull the engine. I am going to do a full engine rebuild-ish, I bought new wisco heads, still looking at the rods I want, if there’s anything anyone thinks I should buy and upgrade I would love help! Trying to push more power but not an insane amount seeing how I want this to be more of a daily but not quite. Thank you guys!

There was seemed like a pressure build up. Only did it once or twice. But that makes sense if I’m putting air into the lines, then I’m trying to start it but the fuel has no where to go. And the injectors aren’t opening. They would just be closed, holding everything including the air.

Dsm use a return fuel system. Excess fuel goes back to tank.

Oh, I forgot about that. Here are photos of crank sensor.

Cam angle sensor "blade" installed correctly? Its the part that bolts to the end of the camshaft. Its possible to install it 180 degrees off.

Oh man, I don’t even know… that’s the sensor at the top correct? Where it faces the metal angling out? Because I’m almost positive that’s correct. I will double check it.

 

[pauleyman]

Yeah it's imperative you put the plate on correctly. Put it on backwards and timing marks dont line up.
Please clean that stuff up. Looks like stuff has been hitting.

I went and got a crank plate, was 25 bucks. They actually have it at Oreilys which is awesome. I think my sensor itself should be good.

The plate looks that way because of me. I accidentally bent it, tried to bend it back but I don’t think it’s correct. Going to replace the plate, how do I figure out what’s the front or not?

6-bolt 7-bolt crankshaft plate differences

Both plates in the link are displayed as they would appear when installed on the engine. The crankshaft sprocket would be placed on top of them as they sit in the photo - you can tell by the dirty outlines on each piece.

You old one will have witness marks where the sprockets are. Just pay attention. Its very obvious once you look at it.

Sounds good, all the markings look right, still don’t think I put it backwards, I’m almost positive in payed attention to those marks the first time around. But I guess we will see when I take the gear off.

Was reading that but I didn’t see anything or pictures that really tell me if it’s forwards or backwards. I think I did it right the first time, but I still want to triple check. All marks line up so I’m thinking that it’s good.

I’ve put on the new plate, and checked all sensors, they’re plugged in, facing the right way, and no check engine lights are on. I’ve tried switching around the plugs, nothing. Nothing every single time.

I don’t want to keep trying so much if it’s just not gonna turn over and burn up my starter. But man it really does not even want to try though.

Good news, and bad news gentle men. I have officially found our problem, there is no spark at all. I mean, I pulled all the plugs and put a brand new spark plug into each of them, and nothing. Nada. There wasn’t even a hint of a spark.

So now, I need help of where to go from here. Thanks guys.

I know there’s a few different things it could be, I’ve read the PTU could be the problem or cables, or the spark box itself, but the cables are new, and the box was working before. I don’t even know what the PTU is, and the most common problem I’ve seen people say is that trigger plate, since my was not looking the best, I’m gonna go pick up a new one tonight since they’re only like 40 bucks. If you guys thing it could be anything else, let me know.

In the last two videos you just uploaded, I hear the first fire. If there was no spark at all, you shouldn't have heard that.
Did you make sure the spark plug wire ordering is correct?

Yes I did, and the first wire was also only with starter fluid, don’t know if that makes a difference if not. But I also didn’t video, when I unplugged every single spark plug and was testing them, it did the same thing for a very fast second. Sounded better actually when they weren’t plugged it. I had plugged in my brand new spark plugs into my coils, all of them, and nothing. From any of them, and I checked and made sure. Not s single one sparked.

 

[DSMPT]

I see, but even if it was with the starter fluid, if there was no spark there shouldn't have been first fire (initial explode).

Got it. Okay. Why would they sll stop working all together then? Unless the spark is that that small and I just can’t see it. Or it’s spontaneous and I don’t know when it’ll spark?

Maybe there are sparks, but you didn't see well for some reason.

What CAM sensor are you using? Can you check for voltage at the plug? Do the injectors click while cranking?

 

[RubyEclipse]

As in what? Because if you mean brand, I do not know.

how can I tell if the injectors are clicking? I can’t really hear. But I can check the voltage, how do I do it, and what volts am I looking for?

 

[Justin DuBois]

The CAM sensor is either mounted on the water neck side on the intake cam (1G and 2GB style) or it is under the CAM sprocket (2GA style)
I was wondering which type you have.

 

[DSMPT]

The car was running before, so take a deep breath and try to double check all connections and installations.
Also you can upload more pics of engine bay and videos, maybe we can find something you didn't realize.

probably easier just to ask does it smell like fuel? Injectors and spark work off the same triggers - the cam and crank sensor. If both spark and injector fail, it points to the sensor(s).

I will have buddies check for me. Because I cannot see very well.

Mines mounted in the front, but I never touched the head after removing it, and it had worked perfect prior to the car running.

It actually does not smell like fuel at all. But the smell from exhaust fumes is so strong, I am not 100%. But the pistons were dry, so that means fuels not sprayed correct?

You can pull a plug and check if its wet - light it on fire to dry it. If its dry after cranking, I'd suspect that the ECU is not getting the crank signal, or possibly no CAM signal. Check plugs snug, wiring intact, measure voltages across the ground and pos at the sensor plugs. look for broken wires - these parts are brittle now days

First time someone told me to light something on fire like that.

So I replaced the crank sensor. And it started!!! I put in the new one, and cranked it, all the plugs got sparked and shocked me a few times. I’ve not been this happy and excited in a longgggg while. My clutch pedal went all the way to the floor though, so I’m gonna bleed it tomorrow because I’m almost positive that’s the problem. I also have to replace a tie rod end, but I can’t get it to stop spinning. So id love pointers on how to get it off and to stop spinning in place. I am genuinely so so excited for this car and to start driving it.

Congrats! We can imagine how you feel at the first startup.. It must be exciting and emotional. You still probably have more things to do but go on.
Off topic, but this thread has bunch of good info, common basic but important things. Many people share their knowledge and experience. People would need this kind of info often especially when they start working on the car by themselves like you or who just buy a DSM.
Maybe you should ask Chris or admin to move this thread as your build thread. So more people would be able to refer.
