2.7 Biturbo no start after engine install
Hi Just finished mounting the engine after a Bi turbo replacement, got the pair for $850 a piece, from turbochargerpros.com, that is new not overhauled. Enyway I can't get the cart started it cranks but no start, there were no fuel at the engine after cranking so I did the fuelpump test prosedure where you remove the fues and hot wire the pump, the pump worked and I now have fuel at the engine but still no start.

Re: check your connection plug to the ECU...
Thank you, I was also thinking of getting the Wag-Com diagnostic software from Ross-Tech LLC, is this a good choice or is there something better or more user friendly on the market. Thanks again Kris

Make sure your cam sensors are working properly. I think if the
rotational sensors aren't functioning then the fuel pump/spark circuit won't fire. Read the 2.7t study guide and figure out what inputs are needed for the CPU to know the engine is turning.

Good news, it is running
Just got it running, I rechecked the connection on the MAF, ECU and the engine speed sensor, the speed sensor connection plug came apart when I pulled lightly on it, so that might have been the killer. But thanks for all the help. Kris
