Mfi Not Sparking

[Guest tobys73]

hi all got a prob with my cab not starting

 

prob is the car has no spark, ive fitted new leads, plugs, rotor arm, coil, amplifier, but still no spark. ive checked all the connections to the coil etc and there is 12v at the dizy and coil and i fitted new earth straps to rule out a bad earth, the fuel pump is priming and i have fuel going to the metering head. does anyone have any idea what else i can be missing out is there any relays/fuses etc that could be to blame even though the coil etc has voltage

 

is there anyone in the Lanarkshire area with a mfi escort/orion that would be willing to let me fit my Distributor to their car to test it or has anyone got a working one for sale that i could have, it is the brown capped bosch dizzy thats fitted to my car

 

any advice is much needed

 

thanks

Would suggest removing a plug. Keep it plugged in and earthed. Get someone to turn over engine while you look for a spark. Its not uncommon for new parts to not work. This will confirm its spark before you go into fueling issues which are vast. I have a realtivly new distributor which was brand new from ford. Only done 4000 miles. £60 which is alot less than the £110 it cost me a few years ago.

hi mate i deffo got no spark i already checked the way you recommended before posting and i also have fuel pressure too, running out of ideas and im down to stripping the imoblilser from the loom and start tracing out all the wires for breaks and shorts

another question is which relays/fuses are for the injection system in the fuse box (k-jetronic) i know what the fuel pump one is(purple under dash) and where does the signal wire on the dizzy get its signal from as this could be somewhere else to look

dont know a lot bout the injection wiring but am fine with fault finding etc any info would be great a schematic of the system would be ideal as the haynes ones aint the best for following

 

thanks
