Fuel Injection Static Timing Help!

Post by zoboe » 17th July 2016 - 3:30pm

Hello all! I'm at a loss with my '71 fuel injected Sqaureback. Had it nearly a year now and he's been nothing but hard work!
The engine had a nasty knock when it first got to me and ran rough, kept cutting out. Gave it a good service and it got worse, so dropped it out and split it open to find several worn or buggered parts. I'm a mechanic by trade so thought I'll just rebuild it but found a shop that could do it at a reasonable cost and it came back to me a month or two ago and I've finally got it back in!
So theres the history of old rattler in my hands but now we cant get the engine to fire up! It turns over and rarely coughs or splutters, once it did spit out a flame ball but had leaking injectors so stopped! Injectors now not leaking, replaced with second hand ones but no firing
I'm going to try put up some pics of my dizzy and drive gear to hopefully help? I've a haynes manual and its timing is well out compared to what that says, the notch in the dizzy rim is in about 7 o'clock position rather than 5 and my drive gear is more straight across than at a 60 degree angle? My engine code is U0480 or as much as I can remember! Can get the rest tomorrow if you guys need it?
I just want to check the timing is correct before we start running off hunting for other problems, other expensive and hard to find problems!
Thank you in advance Zoe

Very likely the firing is coming at the wrong time on all the cylinders. I have heard of folk who have simply moved the leads round on the cap, but that's not desirable as there is a retard on no 3 cyl to prevent overheating on that cyl and that will move to a different one. The gear really should be removed and reinserted correctly, but there is a shim under the gear that you must not allow to fall into the engine. Someone posted on the forum having moved his successfully. If you just want it running and need to establish which is the new no 1 - the timing marks will either show no 1 or no 3 TDC, and you can check which as both no 1 valves will be closed on that cyl. Look at where the rotor arm is pointing and call that the new no. 1. Your timing is TDC (left hand mark) vac hose off. http://home.clara.net/hallvw/type3ign.htm . Firing order is 1-4-3-2.
