:confused: Help needed just put a 1.6 spi block in my nova and then put all my mpi gsi kit on aswell as a recon head and all new gaskets.
It will fire but only for a second and when i take plugs out. number 1 is the only one thats sooty as in fired as the rest are soaked in fuel but they are all sparking strange:confused:
checked compretion and they are all about 110psi
checked fireing order
starting to wonder if my looms ok dont have eml wire on the loom or the octane plug .
cheers steve

Could be related to your fuelling issue??
Is that compression with open throttle???
Check the plug on the dizzy, and the dizzy itself.
What mpi setup is it? Old dizzy type i assume?

red cap with all bosch bits.closed throttle.
the dizzy does feel a bit slack when its off the car but it does spark
Do it with WOT.
Check the plug on the dizzy, and change the dizzy itself unless you know its a good one.
The dizzy is the only thing on these engines that tells the ecu the engine is rotating.

dodgy hall sensor Adam?
i assume you have got the leads on the right place and in the right order?
Yeah hall sensor or coil is a possibility, after youve tried the simple things mr Burgo posted

after car is left for a while it fires first turn and then again dies
are you getting enough fuel up to the rail..
when i did my head on mine, it took dozens of key turns to get the fuel up & bled thru the rail
also check your lifters are full....
they pump up once its running.. if they are ok

a thought a coil either worked or didn?t.could the loom be causeing the bother as mine has had the eml and the ron sensor cut out. all i have is the basics ign live,rev conter and the fuel pump that seems to run on to a blue wire on the engine loom makes it prime tho
also check your lifters are full....on a fresh rebuild you want your lifters empty actually. fuel lines round the right way? earths all on?

yep i stripped the lifters and drained them i did use the lifters out the low miles spi head that was on the new block that am using am sure there all the same tho
something is getting over hot & failing as a guess, it is most likely the coil, or a relay, or its a fuel issue.

can a engine overfuel as in the injectors putting in too much fuel?

Yes, though that wouldnt liely be the case unless they are the wrong injectors or you have too high a fuel pressure.
The plugs being soaked in fuel wont have done them any good. My suggestion is that the gaps are too large. Gap down the plugs & try it. I've had 2 engines now that failed to fire until I did this. Out the box, the gaps are too large & will overload your coil.
When it does run, get new ones.
