well i have a spare 87 sitting outside as a parts car should i pull the coils off of it and try them on my 88t2? also the inital small bounce of the tach does that mean anything? and if it does is it a good something or bad something haha because it barley moves when switched to ON

lets see...
if there is no spark OR fuel, its likely either the CAS isnt working or the ecu is not getting power, as the ecu uses the CAS signal to fire BOTH the coils and the injectors.
the fuel pump also is turned on with the CAS, although the jumper wire and key on, should have it running.
soooOOOoooo, what to do?
1. check the fuses, there are a couple under the hood, which are probably fine, and there is one in the fuse box which is also prolly good, but you start with the basics!
2. if you have a spare CAS, plug it in, and spin it! you should be able to hear clicks, injectors make noise, the plugs make noise (if they dont you can put them somewhere where you can SEE them sparking, without getting zapped yourself. if you dont get anything, there is some fault with the CAS/cas wires/ecu/ecu power/main relay.
3. you get spark, and injector click. sounds like a fuel pump problem now? the circuit opening ( fuel pump in engrish) relay is over the drivers right leg...
coils are the same 86-91 turbo and non, very rare ALL would be bad
