Intermittant No Start

[BloodBath]

Quick rundown.

I did my clutch to get ready for my 35r turbo setup, put in my 1000cc injectors and made a decent base map to get me started. then, i got on to all the goodies on the exhaust side of the engine. I buttoned everything up....... and no start. cranked and cranked and it turned over but no start. The next day I got ready to attemp to diagnose it. cranked and fired up real fast. it ran all day. I started to tune it got the dump pipe put on the wastegate. and called it a day. the next morning went to go do more tuning. and no start. just like the first day. it will crank and crank and crank not even a pop. I do have power to the coilpacks, the plugs look good the top of the pistons look dry...any and all ideas welcome.

it ran very strong when it was even running 10.3:1 afrs under boost. thanks in advance, John

Could be many things. I would firstly look at cranking ms times. What ecu are you using? 10.3:1 is too rich but unless the plugs are getting fouled then it's not the problem.

most likely too rich.. the fact you left it and then came back after some time and started it is a good indication of a rich mixture that refused to fire.

I am running an AEM series 2 standalone. I just havnt been able to fine tune the start.

what initial injector pulse and cranking injector pulse would you run with deatshwerks 1000cc injectors???

I think it is an electrical issue with no power getting to the injectors... time will tell.

Thank you

also i have tried all different injector pulsewidths for the start...all over the spectrum it wont even pop like its trying to fire...

I have ignition at tdc for start up and i Saw it at the plug. with the coil packs un plugged and the 1 plug out i looked in the cylinder while cranking. no fuel spray at all.I have 12 volts at the injector pigtail with the key on engine off.

what controlls the pulse? ground??

fixed. hot wired each injector. to break them free. they were stuck shut. and then open. but now it feels good. just in case you guys experience the same stuff.
