help gte engine in a 1.2

[nova speed]

is it possible to wire a gte loom in to a 1.2 spi loom me and my mate have tried everything but it still wont start i know the ECU is OK because i tried it on his nova. has any one done this conversion before.

[burgo]

yes its possible but the spi loom is the most complicated. post details of what you've connected where exactly

[mowgli]

have you replaced the spi fuel pump with an mpi one? The astra mk3 one fits with a bit of trimming of the inlet pipe.

The gte engine only actually has 3 really essential wires that need joining to the car loom from the engine loom.

Big red to the back of the starter
Black to the ignition permanent live, you need to trace this from the ign switch, its the only wire that still has power when the engine is cranking
And blue/red for the fuel pump.

There is also the EML one that is brown/yellow
The rest are just the original wires reused.

there is a six pin plug on the GTE loom i have connected the thick red wire which is live to the battery and the black wire ignition live and the red and blue fuel pump green is rev counter a brown and white diagnostics there is a blue wire temp sensor i haven't connected this one . Im not getting any power any where i know the ecu is ok because it works ok on his car

haven't changed the pump yet will it stop it running

[mowgli]

first off, the spi pump won't power the mpi. It needs swapping.

Secondly, is the fuel pump whirring for a couple of seconds when you turn the ignition so the red lights show?

Thirdly, if the pump runs, does it continue running when it is cranking?

These questions will help determine if the correct +ve is wired in.

i know there is fuel when i crank the engine don't no how long it runs for i will try and get a pump this week has it got to be of a 1.6 or just any mpi

[mowgli]

any astra mk3, corsa b or daewoo in tank mpi pump will do it, but you do need to measure up the intake pipe in the tank against the nova one & cut it down to suit, of it will squash the end & stop fuel flow.

i have wired it in as u say but there is still no life in it. when i turn the ignition on it squirts fule for a sec then stops. it doesnt inject fule when it is cranking is this right

The would suggest you have taken your switched live from the wrong place. Get a tester on where you have connected the switched live and make sure it stays
I've when cranking

i agree but you still need the mpi pump fitting to make it pump at the right pressure

tried again tonight and got it to spark and inject fuel but still wont start think its not getting enough fuel so im going to try a bigger pump tomorrow

[mowgli]

finally. i've only been telling you for the last 2 days that the spi pump simply won't work an mpi engine

[nova speed]

iv got two pumps from corsa bs one has the same part number as the one from the nova the other is in a metal casing do u think this one will be ok cant remember if its out of an 8v or 16v

[burgo]

are you sure you have the fuel pipes connected the right way? one of the most common mistakes which everyone has made before

[nova speed]

i dont no i know the blue is the feed on the car but dont know what one on the fuel rail. i have swapped them around a couple of times before but not since i have got everything working properly. but i am going to try another pump tomorrow and see if that makes a difference

[burgo]

the return line goes the the pressure regulator.

[nova speed]

il check that tomorrow i thought that made sense the center one the feed but wasn't sure

put the corsa pump in today and got it running. just got to sort out the breather pipes and water pipes to get it running properly. thanks for the help everyone
