As a few if you may know I converted my late spec efi xr3i to fiesta turbo ofac engine and management

Finally got all the correct parts together as I had an pattern part crank position sensor fitted before

But it still won't fucking start!!!!

It turns over very very strongly but just won't actually go

I here the pump relay go under the dash (very faint being an xr3i) the pump it's self doesn't make as notice as it's already to pressure

I have spark just won't bloody go!!!

What are the man things to check? What things commonly cause non starting on fiesta rs turbos? When it was a 3i it was always a case of nothing on the ignition rather than not firing?

Please help me

Could be that map sensors goosed had the same on my mates frst changed the map sensor and it started straight away

Does the fuel pump prime on ignition two? It should prime for 3-5 seconds before stopping without the engine running

If it doesn't then the wiring from ecu too switch earth the fuel pump isn't right

P.s I put a set of stock injectors in mine and they wouldn't work, I tried another set and it fired straight up

It's got the whole inlet from the original xr3i, I've replaced the fuel pump assembly and tank previously it didn't prime this time as it was up to pressure, it's a standard xr3i tank and pump may undo the pressure reg to make sure till prime to pressure

Also I'm gonna chuck another 30 quid worth of super unleaded

I do have VXR injectors but will they work with the ofac ecu?

I have a set of standard injectors if you want to borrow those to try mate, I think my inlet has other sensors on if you want to try those too, may have the map sensor somewhere too, glad to see your cracking on with it mate.
I made a start on the rs the weekend, going to finish the welding next weekend too, well try to finish lol

I tried the same thing

Xr2i blues and they would do nothing

Unplug the coil and undo the fuel cap and turn it over, this will de pressurise the system

Mine will prime every time I try it, if I give it half a minute

P.s mine is running with vxr injectors on my ofab, I had too turn down the co and the fuel pressure

I'm just using my ofab too make sure it all runs before ordering ofam

I have the ofac injectors, maybe I could try them then? I though they were the same as xr3i and xr2i?

They might be but on my car the xr2i ones would not work at all, zero fuel getting past the rail

Give the ofac ones a try mate

marky_g

I shall try that the weekend then
