No power to injectors won't fire
I've been working on figuring out why my car won't run for the past two months!tested compression,spark,fuel pressure,all were good!it cranks and cranks but won't fire.i didn't smell raw fuel in the tail pipes at all.so I tore everything down to the injectors,rented a noid light and didn't get a pulse.i checked all the egi fuses and relay they all were good and got power.i did have it turbocharged for the summer now it's back to stock.i was running the adaptronic ecu.i put the stock ecu back in hoping it would fix my problem but didn't.if anyone could help it would be greatly appreciated!i don't wanna bring it to the dealer they wanna charge $145 to look at it and if they start getting into the wiring it's $138 an hour
hope someone can help this is killing me thanks!

ok, this is a true story, so I am not BS ing you. trust me this is what happened to me and how I fixed it. Last year, when my 04 had 182K on it, I took it to a non-Mazda mechanic (stupid move, but was given bum info by a neighbor about the shop) to do a tune up with new plugs, etc. They had the car for 5 days, could not get it started. I then had it towed to my dealer who went at it for one day. They couldn't get it started, said the compression was shot, should probably replace the engine. So I asked them if they would consider jump starting it, like we did in the old days to get a car started (I'm 64). The Service manager got on the phone and asked if I was sure if that's what I wanted, and so go for it. Well, they called me back all excited, and said that it fired right up, but that it was running really "rough". So I had them do the tune up, plugs, coils, wires, and it runs like a freaking jet now. I also run the car much harder and it keeps the engine in tip top shape. Give it a shot and let me know if it works for you. You might be skeptical but trust me, this is exactly my experience.

Okay thanks! Il have to check it out,I forgot to add before it died it would take a second to start cold and it would run rough til about 5k rpm then smooth out.after it warmed up and I shut it down I would not be able to get it to fire again til it was cold,it did that a few times and now it won't even fire at all.i tryed staring fluid it fired a few times
