BIG No start problem, please help - ZR-1 Net Registry Forums

8upZR1 · 06-06-2006

I am new to this site and Zr1's in general but have a serious sittuation and I thought maybe somebody could help me out. My ZR1 is a 1990 with just under 20,000 miles. The head gasket blew from using purple ice and so I replaced it. While motor was apart I ported the heads, intake, TB. air horn, and headers. I put the motor back together and set cams at 107.5 intake, 109 exhaust. Now the motor will not start. The starter will turn the motor, the plugs are firing in correct order, and the injectors seem to work. When checked, the plugs are wet with fuel, and there is a puddle of fuel under the open headers. I have tried different chips GM and aftermarket, fuel pressure looks perfect, no trouble codes, good compression, good intake vacuum, yet no start. Every once in a while I get a pop and a fireball from the headers but that is it. Does anybody have any ideas about this situation? I am desperate because I have tried every trick in my arsenal. PLEASE SOMEBODY HELP ME OUT.
