H2mildandwild,
thanks for your offer; imight take you up on it. i have been talking to the people at magna and so far they have been quite helpful.
a few days ago i found out that something has gone horribly wrong because no the engine has no compression. we are currently tearing it down to get it fixed (i hope it is just the headgasket; don't know yet...). as soon as that is done i will verify everything with the stock set-up and then i will put the kit back on. so that might when i will be taking you up on your offer. thanks a bunch!

I am confused as to why, with a check engine light, your dianostic tool does not spit out specific error codes?
Did your tool read and report specific codes?
During my install, I crimped a wire to a fuel injector and the cylinder did not fire and the engine ran rough. It ws quickly diagnosed---new wire--no check engine light and it runs great.
If you want, I will go over some troubleshooting on the phone with you--just PM me with your number. I also know the guys at Mag and together we can fix this.

It should run without the new program. Vacuum leak? Could be! BIG-C

Klaus, Circuitguy; i will defenitely check the o-rings on monday. that at least gives me hope again that i did not screw it up totally.
Klaus, i will also check for the vacuum leak on the back of the sc. i checked in general but not in that location yet. THANKS!!!

Sounds like Klaus is right, the O-rings might be missing on the fuel pressure regulator. You woll still have pressure in the rail but not the correct pressure at all injectors. Remove it relube the O-rings and carfully reinstall it. We have installed a few of the Magnachargers and have had this problem one time. BIG-C

put a node light on the injector harness at the misfiring cylinders and see if you have injector pulse.next step do a compression test.
