I have been tearting me hair out on this one. I have just done a top end re-build on my 1.8 i SRi Belmont. After re-assembling the cylinder head and all the inlet and out ley manifold's, the car fired up. But the next day when I went to start the car after an oil. change, the damn thing wouldn't fire. Checked the plugs, checked the spark, (a little weak, but there), checked the leads, plenty of fuel, though it was a little low before I put some in. The fuel pump is working. It makes a vague attempt to fire but very occasionaly.
My thoughs are that there either may be a problem with the fuel control relay, or with the ignition coil, or a combinaltion. Or it could be something completely different?
Am sick after 2 days of work, to not get it running, when I know it should.
Checked the spark at each plug, and is there but not the best. Have already ahd it running with all the plugs and leads currently using.
Am getting a bit of fuel smell from the plugs, could be an air block in the fuel line?
The only reason Y I was thinking it may have been the releay is when it has been really low on fuel, to almost empty tank stage, it was a buggar to get started, but that could be the prob of getting fuel up. The engine had been turned over several times, so you would think that there would be enough fuel up there. I may put new plugs in, check the relay, and fuses etc.
Plugs wern't to drenshed.
Will the fuel control relay from a 2.0ltr GTE be the same as the 1.8's?
Will strip down the fuel pump/filter assy at the back of the car, and check it out, I have a spare to try, if need be.
The fuel control relay is at the right side just behind the expansion tank yeh? Is there a relevant fuse with this too?
Is there only the fuel filter at the back end of the car? Is there one in the engine bay?
yeah filters down at the back wheel
theres a fuel fuse, but the number escapes me. if you are getting fuel then obviously its fine
errrr dunno as to the relays, i would guess they are the same, but the part number is written on the top for you to check
its on the suspension turret, on a hook where the expansion tank is yeah.
errrr, hmmm, not much more i can think of mate if you have spark and fuel then theres just timing left really
or theres no air getting in...try a spare AFM if possible (also contains the ecu in this model, might be a problem there)
clutching at straws and just suggesting everything now tho mate, best off eliminate the obvious first and get back to us.
and 2 days? hell i spent 3 weeks and it still didnt fire first time (dodgy rotor in my case)
Will try out as many possibilities as possible, its just such a pain in the RSE when you finish re-building the damn thing only to be nampered at the last hurdle.
Will let you know hopw I get on, dont have the time until next wkend as am off to London fae Glasgow 2moro? Wanted it running before I left, but hey thats the fun of it.

If anyone else has any other ideas, feel free the more the merrier. No doubt it will be something simple, they usually are Och well.
The relay from a 20lt ain't the same as far as I'm aware. The pins are in a different config. If the relat is sticking give it a whack. If it starts after that then the relay is on it's way out. If that dose'nt work change the plugs it might also be worth while checking the plug leads are in the right fireing order. Oh yeah there is only one fuel filter.
I've been through four air flow meters on my SRi and have never discovered what the problem was with any of them, didn't stop the car from starting tho. Try this web site for some hints and some good tuning tips for air flow meters www.atpelectronics.demon.co.uk. Hope you can get her running, best of luck.
