i just rebuilt my head and had my car down and sitting for about 4months, started putting her back together and now my car cranks but wont start, have spark, compression was 150 150 160 170, my AFPR reads 0 with ignition on. my pump is working, theres fuel to the rail, and some fuel comes out of injectors. i checked the continuity at my clip, and was getting a reading of 90.1 ohms..... spec is 2-3 ohms. and im getting 10v DC with ignition on, not cranking. anyone have any ideas? i did do a wire tuck and had to snip some wires and reconnect them, to untangle the harness. i did not touch the injectors though. any ideas on the causes of this??
 
Charge it up and then back to square 1.
If you don't have DSMLink, you can ground the white/red wire at the fuel pump relay (pin 2) to activate the pump or apply 12v to the A-58 fuel pump check connector on the firewall to verify your fuel pressure. That's easier on the car than cranking.

If you don't see 43.5 psi try clamping the fuel return line off the FPR and see if the pressure rises.

The injectors get their power from the red wire at the resistor pack. It's the common feed for all four resistors in the pack and from them to the individual injectors. The ECU grounds the other side of the injector to fire them.

On a 2G the ECU supplies 5v to the Cam and Crank sensors and they in turn ground that to signal the engine rotation.

If the problem was strictly a fuel issue, it would start with starter fluid.

Did you make a list of all the wires you cut?
 
injectors are tested without power. just measuring resistance. charge it so it has the right amount of power. see what voltage youre getting at the sensors. test the crank sensor and fuel pump
