getting my pinto efi right
Spent last week wiring the ecu and associated wiring and once completed i tested for a spark. Surprisingly it sparked so i thought great now to add
fuel and off we i go.
So i waited for the weekend and filled up turned the key and got no spark.
Having tested all the wiring and the coil everything is working but getting no spark to the plugs. The coil is definately working so what else could
be wrong.
Help please ?

why do you say the coil is working, I mean are you getting a spark from that, have you tried connecting one of the plug leads to it? that would rule
out the dizzy. Never seen a trigger fail as it not got anything to break being all sealed up.

If it worked only recently and then done some some other work, you have probably disturbed a wire somewhere - check all the connections first
including earths before going out and getting new components.

Ah now, does the king lead have the right resistance and good continuity.is the king lead fitted securely. Are you getting a good spark going to the
coil.
Have you considered that the resistor in the rotor arm (between the rotor centre brass contact and the rotor brass tip, embeded in epoxy) has gone
base over apex.
Are the leads out of the distributor the right resistance and getting a spark to the plugs (ALL of them).
Is the fuel pump priming when initial turned on.
Is fuel getting to the injection rail.
The injection rail has its own sub loom. The female connectors (near to No4 injector/end of rail) are known to open out and give poor connectivety
(non function of injectors), check and close up female connectors as required.
The above is a quick/rough and ready fault finder and I hope it helps. First time I played about with a non starting Pinto EFI it took me 2 weeks to
find the injector rail loom plug fault.

i got a good spark at the coil when i earthed it to test it but when the ignition is switched on there is no spark. Its almost as if something is not
telling the coil when to make the spark.

hmm tricky as isn't the ignition control module all sealed up? not sure how you go about checking it and if faulty it just gets replaced.
That's why I still have points on my pinto, at least I can fix them.
