ok so i got a good deal on an 01 civic cause it would just crank and not start, i got it running of starting fluid so i know i got spark, and i have injector pulse when key is turning, the fuel pump comes on, i just recently put in a new fuel pump cause i thought that was the problem, but still not getting fuel up to the engine like no fuel pressure? car has an immobilzer system which i think is my next step, my question is how does that system work and would i still be getting spark and does it just shut off fuel flow? but like i said i hear my fuel pump running, im stumped any help would be great wanna get this thing running thanks!
