Had a hectic week with the e30. Went to pick n pull, got a used unit and it was completely rusted out. Bit the bullet and bought a new one from Turner that took forever to get to me, wont use them again.



Turns out this is the wrong valve and doesn't fit my model car, so I have to send this back now. Fed up with waiting I read a few threads and copied someones solution.



I got it all installed and then when I was cleaning my thermostat I ended up tightening it too much and broke the housing. Dumb mistake, but I have extras chillen at another house.

Im still chasing down a misfire so once this is all back together I can get to work on that.

Been pretty busy the past few days.
Yesterday: Got a new cap and rotor on which helped get the car running a lot better but still has a miss in cylinder 2 I believe. I was also getting a CEL and throwing code 1223 which is for the coolant temp sensor, so I replaced it with a unit from autozone and the CEL didn't go away. I thought maybe the c191 plug was corroded so I cut that out and spliced the injector harness straight to the body harness. This did help the car run a tad smoother, but still a miss in cylinder 2 and a CEL. Also noticed this guy leaking, so I stopped here for the day

Today: Removed the fuel rail to see if injector #2 was clogged but after cranking over and looking at it, it is still spraying. I cant figure out this miss for the life of me. With the CEL still on I remembered the coolant had been diluted a looot with water so I was going to flush the whole system and use the correct mixture, thinking maybe it's giving the sensor a weird reading? I don't know I'm desperate. So I drained all of coolant, and was going to go get some when I remembered the heater valve was leaking. Got the heater valve and core removed, heater valve is completely shot so everything is put on hold for a bit.

I was able to drive the car around the block yesterday, and it's by far the tightest feeling e30 I've had. Unfortunately I plan to sell this thing once it is road worthy.

Double check timing if you're not 100% sure.

I triple checked it and even had another set of eyes check it. Before and after two rotations of the crank. I just want to make sure I have ruled out the easy things before I have to go into the timing again.

I've got the car to run and idle, but definitely have a misfire. I checked for spark and fuel in each cylinder and they all checked out individually. I believe I am getting the misfire in cylinders 2, 4, and 6. I tried swapping plugs from cylinder 1 & 2 thinking it was the plugs had fouled, but it still missed in 2.

I did just do the timing belt, could this possibly be a culprit? Maybe I was off by a tooth? I took a lil video and I'll try to post it in a minute. Excuse the lil vacuum sound, while I was removing the valve cover earlier I broke the line. /: Cold this be the culprit? It was running rough before I broke it.

Here is a clicky link while I try to figure out how to embed correctly

Got a fuel pump from another r3ver today and was able to get the car running. Had to switch out two sets of injectors because they weren't spraying. Guess I've got like 12 bad m20 injectors, I'll probably donate them to the guy in here that rebuilds them and see if he can do something with them.

I need to order a few hoses, all new fluids, and put some more gas in then Ill try to run it again. Does anyone know if these automatics are serviceable, or should be serviced? I vaguely remember reading somewhere it's best to not change the tranny oil, maybe Im trippen.

Got everything put back together today, went real smooth. It's amazing what can be done with a simple tool set on these cars.

Unfortunately I cannot get her to start or even catch a little. Cranks over just fine and has spark so I know those aren't the issue. I believe there is an issue in the fuel delivery somewhere. When I was checking for spark the plugs weren't wet at all. I pulled the back seat and tried to hear the fuel pump but cant hear anything, I should be able to hear this thing with the key in position two right? Could jumping the wrong posts on the starter have damaged my main relay?

[mbonanni]

Figured it out, I have no ground cable from the engine to the body. Made sure this was the issue by connecting some jumper cables from the engine to the body and she finally cranked over.

Ahh, well I definitely did that at first. Could that have hurt something jumping those two?

Guess ill have to pull the starter and get it tested somewhere else. Unless my wires aren't connected correctly? I believe ive got a large red and large black wire connected to post 3 then another medium sized black wire connected to post 1. Smallest wire is capped off. I also tried connecting this wire to post 2 and got nothing from that.

[Balleristic31]

Should be jumping from 3 to 1. Don't go 3-2 because that's dead shorting the battery wire (2 is the solenoid ground) :p lol

In my 4 years of battery selling I only had maybe one dead one off the shelf. They all should come fully charged.

Based off this picture I tried jumping from 3-2 and then 3-1 and all I got was clicking in the relays.

Perhaps a noob question, but do batteries come charged from the store? First time needing to buy new.

[Balleristic31]

You should be able to jump from power (main starter post) to the trigger wire post (black/yellow wire from ignition switch) and it will turn the starter/engine. You don't need cps or any relays to be working to do that! :up:

Love the laguna! Bring it back!

Was able to get the old starter tested today, turns out it works, but the gear doesn't move out. Would I have been able to hear it turning when I tried starting before?

I also got my spare starter installed today. Turns out the extra one I had is from an early model and had three post instead of four. I wired it up normally and capped the extra wire, I believe this just allows for the accessories to be utilized while the car is being cranked.

Unfortunately I was getting no crank, the solenoid wasnt clicking or anything. I got the started tested this morning so I know its good.

When I try to start the car or jump the two posts on the starter with a screwdriver I can hear the relays click. So prettymuch I am left to a no crank issue, any opinions on what it could be? Could it be the extra wire hanging or possible bad relays? Could a bad cps cause the issue? Bad ignition?

[mbonanni]

Got some work in yesterday. We managed to get everything removed to put a new timing belt, tensioner, waterpump, and starter in.

[mbonanni]

Yeah, not sure what he was trying to do back there.

I got a battery hooked up to test out and see what works. Most everything works but theres a few things ill have to check out. Windows, sun roof, and blower motor don't work, as well as cabin lights (probably bad/old). The door chime is still there, and I know most people hate it and remove it but I might keep it. I am also pleased to say all the central locking system works from both the drivers door and trunk.

I went to my parents place yesterday where I keep all my e30 parts and got a few starters to try and fix the no crank, new spark plugs, timing belt, waterpump, gaskets, aftermarket ignition wires, new control arms, tie rods, end links, m3 cabs and a few more things. Going to focus on getting the car running this week before I dive into the suspension though. I also have new brake rotors, pads, hr sports and bilsteins at the house that will eventually be going on.

Also found this, Are these exposed wires for the cruise control, is that what that is? Haven't had an e30 with cruise for awhile.
