I recently just swapped out my turbo's and all the vacuum lines. Now it won't start, it just keeps cranking. I tried unflooding it and I also put new plugs, didn't work. I accidently grounded the alternator power cable and blew the Main fuse and some 15 amp fuse but already replaced it. I triple check everything under the uim if things were connected. I have a pfc and on the sensor checked and it highlighted PIM (pressure sensor), VTA1 (throttle sensor 1), VMOP(metering oil pump position sensor), WTRT(Water temp sensor), AIRT(air temp sensor), FUEL(fuel temp senor). All showed a voltage at 4.99v. also on monitor mode my air temp and wtr temp doesn't show anything but lines. can anybody help???

If you still have a stock ecu plug it back in and see if you can get the car to start. If you have the same starting problem then you'll know you did not burn out the ecu. Try this first as it will save you alot of time trouble shooting. If you don't have one borrow it.

Always undo the battery when removing anything under the hood. Reseting radio stations is much cheaper than replacing fuses and other components.

I still have the stock ecu and I plugged it in and it did the same exact thing. thanks

At least you know its not the ECU.

I understand that when the PFC highlights a sensor on the sensor/switch menu that there is something wrong with that sensor or the wiring.

Pull one of the faulty sensors and perform the sensor check per the factory manual. If the sensor checks out then most likely there something wrong with the wiring or a fuse. Find the fuse and check for continuity between the fuse and the faulty sensors plug.

Good luck.

yeah, hopefully it will be some easy wire fix or some fuse i some how missed. all I need is fluke meter now, but everything was working fine before I took everything apart. thanks for some input.

Do the basics, check fuel pressure. Check for spark.

Alright, I got it to start but it idles like ****. It will die out if i don't hold down on the gas. The problem was, one wire pulled off or came the connector that goes to the ecu. I made a temporary jumper wire and it started up. I did the unflooding procedure the day before and I read certain threads about it runs like crap once unflooded. Also when i replaced the vacuum lines, I took out the rack, I had to disconnect the fuel lines and left it exposed. could it be possible that moisture got into the fuel lines then to the fuel filter and made it swell up or clog it? I rev it up here and there to push out what i can. How long will it idle like this? anybody got any input of what I just discussed, thanks.
