Engine not starting help please!!

[StealthyGecko]

Okay so I've recently taken my MR2 from a Rev 2 engine to a Rev 4 engine after cracking a piston ring or two on the Rev 2, I've got the engine in the car and pretty much got it fully installed except for a couple of things and I was wondering if anyone can steer me in the right direction.

first problem:
When pressing the clutch it feels as though there is nothing there I've reconnected the clutch but is there anything I may have missed or anything I have forgotten to do?

second problem:
when trying to turn the engine over for the first time the dash light up as expected, the fuel pump kicked in but nothing else, what could be causing this?

third problem:
this is probably linked to the second one but basically when the car would start me and my friend started hunting around for for any loose connections when we found this buried under the distributor...

does anyone know where this is meant to be plugged in? as we have searched and searched and cannot find a home for it anywhere. In case its not clear where this plug is situated its near to the engine bay fuse box and the back wall. if anyone can help with any of these problems it would be much appreciated

that plug looks like the one for the speed sender on the gearbox, although not sure if tubby and NA are the same, looks exactyl like it though

Thanks mate any ideas where on the gearbox I would look for that?

have you definitely got the slave cylinder located correctly on the tab that it pushes against. if its just pushing against air you wont feel a resistance. If it is then try bleeding it.

For not starting its worth checking all the fuses in the fusebox in the frunk by the left strut. If one of those (fail to remember which) is gone it wont turn over.

Look down at gearbox and its slightly to the right and towards the rear firewall. Plug points upwards

I believe its located correctly, but will double check this, also could you tell me how I go about bleeding the clutch?

will do I'm hoping thats all it is, but just in case can you think of anything else to check, unfortunately the unit my car is in I can't get internet so I need to gather as much information as possible before going back up there.

Nice one will make sure I find and secure this

Thanks again

theres a bleed nipple on the slave cylinder. Make sure the fluid is topped up in the frunk, get someone to push the clutch, open the nipple, if fluid comes out it probably doesnt need doing, if air comes out wait till noises stop and close nipple, release pedal, push pedal, open nipple, wait, close nipple, release pedal. repeat.

if the fuse is ok and you can hear relays clicking when you turn the key then power should be getting the the starter motor. check that the starter motor is wired correctly and has power. Its got a large power cable that goes to it and a smaller cable with a washer like end on it. Do a search for some pictures, i know ive seen some of the correct setup on here somewhere. A thread within the last month or two answered this question. Also check the battery voltage is enough to turn the engine over. Check whether the golden power connectors in the engine bay fuse box have power. failing all that i think the starter relay goes sometimes (green one in the boot by the ECU?) changing that might sort it.

Doesn't that plug go on the ignition coil / igniter?

i think the igniter has a small 2 pin plug and a large 5 pin plug. That one in the pic is 3 pins, as is the one for the gearbox

Was your REV2 a UK model or import? was the REV4 engine UK or Import

If miss matched then you may need to do a bit of re pinning on the passenger side loom. Unless you changed the passenger side loom as well.

I take it you have connected the life to the starter motor?

The plug goes to the gearbox sender as stated earlier on in the post.

the rev2 was import and I believe the rev 4 is an import too.

the life has been connected to the starter motor.

apologies for sounding like a complete idiot at the moment unfortunately when i took this project on I had someone helping me who knew his way round pretty much any engine sadly hes been snowed under for months with work and personal stuff and the guy who's unit im using has been on at me to get this finished and out of his hair so I've taken it on and to be honest I think i've done pretty well so far its just the lsat couple of hurdles I need to get over, could you tell me where the slave cylinder is as I'm not sure, also do the brakes and the clutch work from the same reservoir in the frunk? as off the top of my head I can only picture one two in there one for the brakes and one for the power steering.

also can anyone point me in the right direction of somewhere I can get a couple of those clips that hold the gear linkage in place in the engine bay (the big squarish ones, not the hitch pins) as I've done some googling but so far not found anything.

TIA

ok i did a little google search on this and found you may have a MASSIVE headache ahead.

The Rev4 was fitted with a Key transponder for security without this you will never get the engine started as its linked to the ECU. So the key, transponder and ECU is needed for the engine you fitted.

If you can't get this then there is a way around i but means you need to get a REV3 engine loom and ECU

That's just what i have found on the net

ah no the engine came with a rev 3 ecu as it was originally being used in a mk1 project so the transponder shouldnt be an issue i was assured that the engine worked and has been running on this ecu

its been a while since i last bled my clutch but im pretty sure its a separate reservoir. I cant picture where either but it must be on the frunk bulkhead somewhere.

its going to be easier to bleed the clutch from underneath so thats how i will describe it. If you go head first from the rear of the car until you reach the cabin bulkhead and look up towards the gear linkage area you will see a metal tube coming from under the car, which turns into a flexible hose which then attaches to the slave cylinder on the gearbox. i think the bleed nipple is on the top right hand side of the slave cylinder

YES!!!!! I'm finally learning something I thought thats what that was, I noticed that the nipple looks like a nut at the base so I twist this to open it?

[dantheman]

indeed, it looks a bit like the male sexual appendage but with a different kind of nut at the base in much the same way if you twist the nut fluid comes out.

you dont need to turn it far, 1 or 2 full rotations. make sure you dont overtighten it. Also if its stiff use a flare spanner to avoid rounding the nut.
