calling all mfi rst experts
ok im sticking this up for a mate.
he bought a car for next to nothing as he wanted the engin loom and tank etc to do a conversion.
he didnt want his car to be off the road for to long so decided to try and get the engine running in the car before removing it.
he encountered a few problems along the way with the loom. (it was just chucked in the boot, never actually run in the car)
he struggled getting the fuel pump and things to run.
he now has a spark and is using a 12 supply straight off the battery to get the fuel pump running.
there is definately fuel making it into the engine. but it just wont start.
we tried pumping the butterfly flap thingy (i think thats the technical term for it anyway) in the metering head but stil now joy. it really does ound like its not even trying.
a few things i noticed that i wanted to query was this:
2 female spade connectors on the ecu loom just before the multi plug. these have nothing going to them
also the firing order is 1,3,4,2 if i am correct. does this go clockwise or anticlockwise on the distributer, is no. 1 the top one?
basicially what would be really handy is a quick list of things to check that would cause the car not to start.
someone done this for me before when my novas engine didnt start and it was very very handy. (things like cps, fuel pump relay etc)
one last thing, the small boost hoses. on the engine they go from the top of dump vavle to the square inlet manifold thing, and also from there it goes to the ecu and it T's off to what i think would be for a boost gague but there isnt one at the moment so that isnt going anywhere.
any help and advice would be great as he was kind of hoping to get this engine running and then do the conversion before central day!
cheers in advance guys

i dont know what the 2 spade connectors on the loom are for, i hav seen them on other looms but not doing anything
with the metering unit
crack off the top of the injectors on it, turn igntion on and press down the flap fuel dhould come out if it does then the metering unit is ok if it doesnt its siezed and needs replacing, you will always have fuel at cold start aswell even if its knackered
the timing is 1 3 4 2 heres a quick diagram of how the leads go looking at the dizzy from passenger side
fuel pump could be down to knackered fuel pump relay

i know the engine was ok as it came out of my friends car running then he started the conversion, do you thinkit could be fuel not getting to the inlet from the metering head so theres no attempt to fire?

there mite be fuel at metering head but is it distributing it to the injectors
have you checked the plugs to see if you have spark
i would do a compression check though just to make sure

i bled the fuel lines to the inlet and is def getting fuel and has also got a spark so i cant think what else other than compression, although it was a running engine unless its not getting air to ignite the spark? how do i go about doinga compression test if i cant warm the engine up?

well if u have spark and fuel it should fire
is the timing correct on it?
id judt do a compression check tbh
i know ur supose to do it warm as the rings will have expanded but it should still show up a bad reading when cold if sumthings a miss

what could stop the air getting to the spark?
