Default HELP car won't start

Alright well about tWo months ago my car stops working. One day it fired up but it wouldn't stay on unless I kept my foot on the gas, then after a cuple min it ran fine. The next day same thing but I just left it and thought it was the cold. Well now two month later it won't start. I thought it was the fuel pump so I replaced that and the filter and nothing and I have spark. The fuses and relays r fine as well. The car cranks but it won't fire and now I have no idea what to do next. Maybe cam or crank sensor?? Idk but if u have any ideas pleas tell me haha cus I don't

Thank you Jason

start with the basic's - fuel, air, spark and voltage.
(just make sure the battery is charged and good)

Check fuel pressure.

check spark

you could try to disconnect the maf and attempt to start it. it will run shitty but it will still run.

with out crank or cam signal it will not start, you can check this with a half decent scan tool by checking the relation between the cam/crank sensor. they should read almost identical.

If your getting spark like you say - attempt to start it on startig fluid. you are missing one the necessaties listed above.

good luck.

Try swapping your ign relay with a fan relay.

I am not sure where to tell to you to look next. Is the compression where it should be?? I wish you were close i could come look at it in person - were you able to get a scanner on it to see if it is getting crank / cam signal? let me know the exacts as far fuel psi when cranking, what compression readings were ect....

Just to let you know my Z28s relays all tested good too, but car still had an intermitent no start. Turned out to be the ign relay, but it tested good.
