why wont it start...

[280zgod]

well of course i get the engine all back together and ready to go but... it wont start. ive got spark, my injectors say they are firing, and i have compression. although its weird, the spark plugs are completely clean but smell like gas. everything should be close to time since i took the engine apart and put it back together the way the FSM said to (i.e. putting the correct cam chain links on the timing mark of the crank sprocket and cam sprocket and installing the distributor in that 5 degrees position at TDC) My mechanic gave me a noid light to confirm my injectors are firing and they are. he also gave me a test light to check all my grounds but im not sure how to use it. fun times. anyone have any ideas why the car wont start with what ive said. for some reason i dont think my fuel pump is working and that may be the issue but then again i can smell a ton of gas when i crank the engine. so i dunno. gunna go check the fuel pressure once one of my friends can help me do it. but any ideas as to why the car wont start would be much appreciated. thanks for your help. ~Jerrod

Well i am no expert on any z for that matter a fuel injected motor, check the fuel pressure like you said you are going to, not sure if you have a ecu on the 280z but if you do I would confirm it being good, if you have a stand alone ignition the 80 model black box on the side of the distributor check that as well, your air flow meter is working ok as well? these are just thinks I know will not allow an injected motor to run if you are getting gas, probably didn't help much I think someone else will get more specifics for ya, good luck
