Need Help.. Engien Not Starting!

[r33_nikolas]

hi, i purchased a rb25 ( turbo) long block for my car about 6 months ago unsure of whether it was a s1 or s2 engine.. i only recently finished installing it into my car.. today i went to start it and it wouldnt start.. now my original engien in the car was a s1 so i plugged everything off my s1 engine onto this new engine.. i have some doubts that it could be a s2 engine because the coil pack cover was slightly different at the back to the one that was on my s1 engine. now if the engine was a s2 engien would assecories come on if i put the key in? i'm going to change the battery tomorrow to see if that is the problem but i would like your thoughts on the matter..

thanks

Did your s1 motor have an ignition module? and have you fitted it to the new motor?

[r33_nikolas]

yes the s1 motor had an ignition module and i've fitted it to the new motor

Yeah just double check everything battery, earths, connectors etc. You should still be able to see the dash lights when you put the key in. Can you hear the starter motor going or the fuel pump priming? or is just totally dead?

[r33_nikolas]

no fuel pump priming and no starter motor going..

Probably like you said, just the battery.

Got a multi-meter to test it?

[r33_nikolas]

nah, dont have a multimeter. i'll buy a new battery first thing and giv it another shot

let us know how you go.

If the car has been sitting for a while the battery is probably dead.

also check fuses. you may have shorted out something and blown one of them when you've done the swap.

[r33_nikolas]

ok i bought a new battery and installed it... i checked thoroughly to see if everything was plugged in and found that the earth cable wasnt mounted onto the engine.. I put it to accessories, the fuel pump primed this time. i go to start it and the started motor makes a noise once and then all the dash lights go off and have to disconnect the battery n put it back on to attempt again and still the same thing happens.. any ideas.. also checked all fuses.. all ok

[BAMR33]

Sounds like the terminals aren't tight enough, mine did the same thing a while ago when I took the battery out.

[QWK32]

check that the lug at the end of the earth cable that you attached to the engine is clean and the surface you bolted it to aswell, you've got to have good metal to metal contact.

[r33_nikolas]

there is good metal to metal contact and also the battery terminal is screwed on tight.. what i'm worried about is that it could be a series 2 engine and i've hooked up s1 ecu and s1 ingnitor module to the s1 coilpacks. But if it was a s2 engine would it be priming the fuel pump if it has the wrong ecu in it?

[r33_nikolas]

oh and also is the loom to a s1 and a s2 the same?

The engine doesn't mean anything

If you have a Series 1 ECU, loom, Ignotor pack, and coil packs, then it will be fine.

You might have to think outside the square. Grab a multimeter and go to town!

Tried a different ECU?

[r33_nikolas]

i havent tried a different ecu, however all the sensors and ecu and loom were all workin on the other engine. the only thing that i can think ov would b that i have a series 2 engine with s1 components on it. also i wouldnt know where to start with the multimeter ( never used one before)

[The Mafia]

mate, the Head and block in the Series one and two would have no differences.

Only the wiring loom \ ecu \ coil packs etc. So you've effectively downgraded the entire ignition system down to a series one, which will be fine. So a Series Two engine and head with a series one ignitor pack, wiring loom, ECU and coil packs would work fine..

Unless the wiring in the rest of the car to the fuel pump or something is different?

[QWK32]

if you go back to one of his earlier post he says

the fact that you have a series 2 motor being controlled by a series 1 loom doesn't have anything to do with it. you swapped everything over. didn't you?

have you checked your connections to the starter motor?

its abit worrying when you say you wouldn't know where to start with a multimeter and your attempting to fault find a clearly electrical fault. i'm not having a go at you, everyone has to start learning somewhere.

to me it sounds like you haven't got enough power going to the starter. bad connection somewhere? altenator to starter motor connection?

[r33_nikolas]

nah nothing else is different.. i'll give it another check over tonight when i get round to it and post results.
