Since Pete's tied down tonight with the GF unit...

We did a flyby 15 minute troubleshooting effort:

Fuel flow: check
Re-inspect cap and rotor: check
Pull injector plug and check for voltage on ignition attempt: FAIL

Interesting.

Testing his coil in my car for kicks. Give me 20. Make that 45... boss just announced my Fatherly duties for the evening...

Check to make sure you are getting fire from the coil and fuel pressure in the rail.You need to figure out what you are not getting,fire,fuel or air!

Ok, do this check; take an exacto knife and open the boot of each injector plug... you will likely find the wires are bare and shorting. This will be more likely if you have R&R'd the injector plugs many times or the wires leading to the injectors are kinked and stressed. THIS WAS MY NO START PROBLEM and it was fixed by replacing ALL 4 injector plugs (all 4 were crap.) Sadly, I "fixed" all kinds of stuff before discovering the actual problem... I've written this here before, but no one seems to take my word to check this... oh well...

BTW, you can tease the wires apart and crank the car to see if the fix works, before doing any soldering. If any one of them is shorted, it wont work though, so you have to check all 4 to be sure.
