Car wont start! Help!
Okay, so I've had a thread over on cr.net but there's really only one guy giving me advise, and I posted the thread over a month ago and the car still wont start. So here's some info about my situation, I hope you guys can steer me in the right direction. To start off, I did a wire tuck about a month and a half ago. Drove the car afterward no problem. 2 days later I went out there and the car wouldn't start. All plugs have strong spark, all plugs are dry upon removal after cranking. With diagnostic F/P and GND jumped the pump made noise. Without it jumped the pump made no noise at all in RUN or cranking. Either way the car doesn't start. Fuel Injector relay clicks when I turn the key. Fuel pump is getting 12+vdc. I removed a fuel line before the fuel filter; fuel came out. Removed a line after the fuel filter; fuel came out at the same rate approx. Followed the lines up to the front of the car and found them next to the intake manifold. Fuel did not flow out of these and if it did it was a small drip. Replaced the fuel pump. Fuel now flows out of the lines under the hood at a strong rate. During all this I have the fuel pump relay jumped because otherwise the fuel pump does not respond. I sprayed starting fluid in the intake mani and the car coughed a little and tried to start. I removed the fuel rail, with injectors still attached and no fuel came out of the injectors with the new pump. Obviously all 4 injectors didn't fail at the exact same time (or did they?) Maybe the Fuel Injector relay is clicking but not actually working? FPR went bad? Anybody have any other suggestions?

Possable you reversed the feed and return lines to the rail?
if not next i would suspect the fpr. try restricting the flow on the return line. (vice grips)
also check for a losse or disconected ground. As you just did a wire tuck there is a good chance you may have missed somthing.

The FPR rarely goes bad. I wouldn't concern yourself with it.
The fuel injectors need to be told to open, you're concentrating on the fuel pump, it could be something electrical. When you take the oil cap off, can you see the exhaust cam spinning with the starter?

You're better off asking here, as i have no idea what i'm talking about. haha
That was the last thing i said in your thread on CR though. Something isn't telling the injectos to fire, once we found out we has fuel at the rail.
This has been a crazy nightmare though. You had symptoms of other failures, but when checked it wasn't it.

All plugs have strong spark, all plugs are dry upon removal after cranking. With diagnostic F/P and GND jumped the pump made noise. Without it jumped the pump made no noise at all in RUN or cranking. Either way the car doesn't start.
Fuel Injector relay clicks when I turn the key. Fuel pump is getting 12+vdc. I removed a fuel line before the fuel filter; fuel came out. Removed a line after the fuel filter; fuel came out at the same rate approx. Followed the lines up to the front of the car and found them next to the intake manifold. Fuel did not flow out of these and if it did it was a small drip. Replaced the fuel pump. Fuel now flows out of the lines under the hood at a strong rate. During all this I have the fuel pump relay jumped because otherwise the fuel pump does not respond.
I sprayed starting fluid in the intake mani and the car coughed a little and tried to start. I removed the fuel rail, with injectors still attached and no fuel came out of the injectors with the new pump. Obviously all 4 injectors didn't fail at the exact same time (or did they?) Maybe the Fuel Injector relay is clicking but not actually working? FPR went bad? Anybody have any other suggestions?

So even with f/p jumped, you don't have resiudal fuel on the injectors after cranking, but you do have strong spark events?

There was some on the injectors when I pulled them which further confused me. But with the pump jumped and key set to RUN with the injectors pulled, the did nothing.

Interesting. If you can confirm that you're getting fuel pressure AFTER the rail(pull the hose connected to the Fuel Pressure Regulator and crank the car) then the next step in the puzzle is injectors. Have you checked for 12v at the fuel injectors when the car is in the run position? If you do, then When you're cranking it, can you feel the injectors click? If you touch them while the motor's cranking you should feel them vibrate just a little. If they're gummed up, or they're not being grounded by the ECU, then they won't activate.
<- ran into a junkyard motor with 4 bad injectors once.

If you're getting a spark, then the CAS is working, which means the fuel injectors are also getting power, since they all share the same 12v source.
So if we are sure the fuel pump is running and the fuel lines are in fact plumbed correctly, then the ECU is unable to control the injectors, so it either failed or the wiring to the injectors got messed up in the tuck.
Can you confirm the fuel line going to the FPR goes back to the hardline closest to the radiator, which also typically has a white paint dot on it from the factory.

Getting no power to the injectors. Going to see if I can jump the fuel inj relay and maybe get power to them. If that doesn't work ill deloom all wires going to the injectors and try to find a break in one of them
