when you say "cranks" does that include the camshafts as well as the crankshaft?

Considering it started once after the change in coil packs i would say yes the cams are turning.......

I take it you are not getting spark & that has been checked?
if not check it & even recheck it

I would also check to see that you are getting fuel,

check silly things like alarm (if you have one) simple check for this is disconnect the main alarm module, this will disable the alarm & if that is the problem the car will start

after you have checked these, report back, & we can get into some more details....

good luck

This is beyond my knowledge, but since no one has mentioned it; fuses?

again, the car (if i read correctly) has been started once after the breakdown, a fuse would not have allowed that to happen
:wink:

Back again thanks for the replies
ECU now being tested , It does have an alarm but it was disconnected years ago but remains in the car ,I thought maybe it was the alarm but why would it start once when the cas was reinstalled and then again when the coil pack was installed and not again will tell you what happens hope it will be reasonably painless :roll:

Still think its the cas again !! thanks guys

So your 94 NA8 has got fuel, but no spark, & the cams turn when cranked indicating the cam belt is intact?

Could be ECU unless of course it's tested ok since your 2nd last post. Conti had problems with an ECU capacitor leaking over a couple of other components. While he was able to get a new capacitor, the value of the components couldn't be indentified & couldn't be replaced, so he had to get another ECU:

dracomjb had a similar problem which turned out to be something other than ECU:
