2G No start no fuel. P0105, P0110, P0115

Hey guys new to forums.

So first my car is a 97 GST and I've had it about 5 months and the thing has been just horrible with chasing problem after problem. It's a built bottom end 7 bolt stock head. I have 95 ECMLink, FMIC, Evo 3 turbo pushing 26psi daily.

Problem: I was driving the car all day. I stopped at the bank came out to the car it started fine. I went maybe 3 blocks and stopped at a light. I took off in first made it to about 4k rpm and as I was about the shift I got a CEL. The car backfired so I shifted to second and I went to accelerate and the car started to chug and buck. I pulled over and shut it off and. Now it won't start just cranks.

I have spark and fuel at the rail. I changed the fuel pump to a brand new Walbro 255. I scanned the CEL when I got the car home and it had 3 codes P0105, P0110, P0115. The car has fuel but the injectors won't open and I'm so stumped. Plugs are bone dry.

Have you tested for power at all the injectors?

You've got two MAF codes and a coolant temp code and no fuel. Check and make sure everything is plugged in and nothing came loose like the maf plug or something. Check that your injectors are actually firing. I think you can cycle the injectors through ECMLink. What size injectors do you have? 26 is too much for stock injectors.

The injectors aren't stock they are aftermarket for sure but no idea the flow rate. The car was fine for months now it's doings this out of no where. And yes all injectors have power on the constant post but aren't getting the signal to open

Would a faulty MAF throw the mass air temp and Baro pressure codes and cause a no start? Like if those sensors are bad in the MAF then will it stop the injector from pulsing?

Posting and getting others opinions is good for problems that we don't normally see but for something as common as a no start we ask that you search first. I spent hours of my life coming up with a pretty robust 2g : No Start tech article that walks you through testing and troubleshooting.

How To Diagnose A No Start
​

Welcome to the site, search first and then post if you have any questions about the info you found while searching. Read the article I linked to above, then post your findings if you've got questions...

Good luck, we've all been there!

test the cam sensor. crank sensor runs the fuel pump and ignition spark. cam sensor runs the injectors. a bad ecu can be the issue to. test the cas with a multimeter in 12v mode. put a 12v wire to the cas power and ground it. ground the multimeter to the cas ground and power tip to the signal on the cas. should see 5v-0v-5v-0v. if the engine overheated that will kill it. test the injector resistance to. all should be the same or within .3 ohms of eachother. i don't remember what the number to look for was.
