Chimaera wont start!! Help please

[cerberaman]

Any Ideas??
I've got a 1994 4.0 Chim that wont start. Fuel pump primes & works when turning over.
I've got a spark at the plugs & when I pump the accelerator it smells as if there is fuel getting through.
(All fuses are good & both relays are ok)
Doesn't make sense!!

If you can smell fuel you may have flooded it ?

If you've got enough charge in the battery (or can charge it first) try turning the engine over on full throttle.

I was shown how to do this by an AA patrol man after I flooded my chim. It needed a good 60 seconds turning over on full throttle before it started but start it did. Lots of smoke too!

Not flooded, it's been in this state for over a week now.

I still think it might me. It was only after 3 or 4 days of trying to start my flooded chim that I called the AA and they sorted me out in about 10mins.

Cheers for that, got to be worth a try, would be fantastic if it worked.
I've been worrying about all manner of things like dead ECU etc.

If I have a floded engine, or even if I'm just trying to start a difficult engine, I use a blowtorch on the exhaust manifold to get some heat into the engine. Makes starting much easier!

Taking a blowtorch anywhere near petrol fumes doesn't seem clever to me? If it really is difficult to start, may i suggest you have problems elsewhere?

The petrol "fumes" are inside the engine. I guess what I really meant to say is that if you're expecting difficulty starting, you can warm the engine first. A warm engine always starts easier than a cold one. It's something I thought of when trying to start my lawnmower - the first start of the year is always so much more difficult. I just used a hand-held gas torch on the exhaust manifold on the basis that the exhaust manifold could best cope with directly-applied heat.

Some of this in the intake works well.

Still no joy, Tried turning over for at least a minute with foot to floor!
Back to the drawing board!!

Safer to take the plugs out and let the fuel evaporate.
I agree with the foot flat down. You could also try that with the fuel pump fuse out to ensure no more fuel is pumped in whilst you are turning over.

Got it going briefly today.
Took all the plugs out & cleaned them up then car went & ran nicely. Took it round the block & broke down!!
Started up again so went home where it stopped again outside the house (luckily) then wouldn't re start.
I'm now thinking the coil might be weak & stopping when hot or under load (it was fine whilst ticking over for 15 mins) Maybe all the turning over to try to start it gummed up the plugs, does this make sense to anyone?

Mine would not start last year, same symptoms i.e fuel pump priming and spark at the plugs, it turned out to be a coil which was breaking down, providing a weak spark. This was diagnosed with a known good coil.

Ps my advice is get it to the experts, you can spend lots of time, money and frustration swopping parts. David Gerald spent half an hour and diagnosed the faulty coil.

I've got a good spare Bosch coil you can try? Dont know where you are though.

[cerberaman]

Thanks for the input, Just tried a coil but still the same, so last resort is the ignition module, it arrives on Tuesday, so i'll let you know what happens.
cheers

Are the plugs black? A faulty AFM will make the engine over fuel and soot the plugs so it wont start.

[cerberaman]

New ignition module has it going again!!!! not tried for a long run yet as I ran out of time but will see tomorrow. Now all I've got to do is sort out the tick over, it was fine before but won't idle now, but that should be a bit easier.
Thanks all, for your help.
