now wont start
now wont start okay i have been doing a swap in a 93 chevy 1500 i put a 01 ls1 in it alot of you have helped me with the wiring. well we got it running but it runs shitty when any more than 1/4 throttle i have been told it is the computer needs to be programmed for the heads and cam i did. well that is not the problem now i cleaned up the wires and went to start it and tried to start then just turned over. i am getting fuel and spark but just wont start for ****. i went back over my wires and they all are still hooked up. and right. the wires i got rid of was the wires with the obd 2 and vats wire and all them in that connector which wasnt hooked up anyways. could my truck been running like crap cause somthing was fixin to go out and now it went completly out when i went to start it? but what couldve went out to make it not start but be getting fuel and spark? thanks for any and all info
good fuel pressure i have a fuel pressure gauge on her. also the plugs were black as hell but changed them and still the same thing? i know i need a tune but it was running and now nothing hell i even drove it a few times around the block
okay the wires i got rid off was not completely taken from the pcm i still have the obd2 wire hooked up to my plug in connector for the obd2. the only wires i messed with was the blue and white connectors with all the wires in them that did not go to anything i got the obd2 wire by the computer and didnt know it went all the way to those connectors. that is all i messed with was the blue and white connectors sniped the wires right by the harness since they didnt go anywhere. the reason i say i am getting fuel is you can smell raw fuel while we were cranking it over trying to get it to start
my computer was previosly programmed to take vats out that wasnt hooked up i have all the wires for the obd2 connector hooked up a two grounds, one power and green wire from pcm hooked up to it.

I had previously posted the noid light 3x, including the Helms diagnostic procedure for non-firing injectors.
Instead of doing any of it, he yanked his PCM and sent it off for tuning...go figure. So I gave up and deleted the posts.

um no negative i gave up and decided to go ahead and get it tuned cause it was running shitty before hand and i was told the heads and cam is throwing it off. so i decided just to get it tuned and deal with the other problem when it gets back here so thank you
