Starting problem!
Just changed the headgasket and started it up. It wouldn't idle, but ran if there was a little throttle. The injector gaskets i guess were missing so gas shot out finally and it wouldnt start.
i then installed the injector gaskets and tried again. no fuel coming out of injectors. made sure the plugs were all connected. reset the ecu.
the injectors are now firing, theres spark, and plenty of compression.
am i missing something? it wont fire.
EDIT: Oh yeah by the way, the head had to be shaved since it was warped. my compression tester reads about 160 psi.

try ressetting your ecu again? do you have a piggy on the car? I only ask that because for some weird reason while i had my car torn apart my piggy back voltage levels changed and caused my car to not idle. easy fix though

I've replaced or troubleshot a handful of head gaskets on cars (that weren't VVT/cam timed) but when the cars wouldn't run it was either because of
a) the fuel pump relay or fuse shorted, you weren't getting fuel.. and then you were, how did that happen? did you flood your car trying to get the engine to turn or does the fuel pump even prime when the car is put in to ign? Are your fuel lines backwards (buddy's 180sx would't turn because the fuel lines were backwards, he had spark, good compression, but no fuel so it wouldn't fire, we scratched our heads for awhile over that one..)
b) timing was not correct, did you use a timing gun or did you verify by hand cranking?timing being one tooth off on the cam gear can sometimes cause a car not to turn over
c) distributer cap needed adjustments or the coil packs and plug wires weren't connected proper
d) there was a vacuum leak/vacuum lines were not routed properly.
If you have good compression in your cylinders, you're getting fuel from fuel lines to your injectors, and you have good spark (timing, fuel delivery and ignition systems are sorted properly) then I would double check the vacuum lines and routing for leaks, even check the egr
When you get it running let us know what was up..

the reason i was getting fuel and then didnt was because the injector gaskets were missing and after reving a couple times the gas shot out where the injectors plug in and the cel light came on. i think the ecu wouldnt let the fuel shoot because the error code it threw because i reset it and now theres fuel.
ive yet to figure it out. i want to pull the code and see what it is. but damn scanners are expensive.
do you guys know if our car throws a code from there being coolant in the oil? thats the only thing i havent changed out is the oil. its still a little milky.

I think it would still run with coolant in the oil, it would just burn it off and smell a little weird.. I don't think there's a sensor that reads oil composition, just the oil level and temperature. If there was it would be awesome, your car would be saying "THERE'S SOMETHING IN MY OIL AND I DON'T LIKE IT!" haha.. unless there actually is...hmmm..
Well, if you have coolant in your oil that means that a head gasket is blown or not sealed right which is not good. I'm guessing you got the coolant in your oil when you changed your head gasket.
Coolant in your oil is also being used to lube your bearings. That is also bad because it will damage the bearings if prolonged, but that would have to be for a while and a lot of coolant.
A code won't be generated for coolant in oil, but you may get a code for a leak (head, manifold, ect)
