ok good call on the harness ...so that is not the problem.

98s are 28# where 99-00 are 26#..i doubt that is your no start problem. i am with cutlass on this one..check your relay

I think my stock 98 injectors were 28.8 lb & the 99 & up are 26 lb...

:yep:

**Butch2000** · 04-14-2010, 04:40 AM

ok , so do the injectors and coils fire off the crank signal or cam ?

**Cutlass** · 04-14-2010, 06:09 AM

Both but it can run on crank sensor only I think.

**Butch2000** · 04-14-2010, 06:15 AM

ok , did some searching , the part number for the cam sensor on the 98 vette and 99 ta are different ? will this cause it to not start ,

**Butch2000** · 04-14-2010, 06:28 AM

ok , so , I think the cam sensor is giving me grief , I'm going to change that and see if the problem is corrected ?

that i cant be 100% positive as i have never had to do it..but i would say yes..just for the room.

sensor is to long to come out ,without pulling the intake , kinda shitty , but will update if that solves the problem

intake removal is easy my friend. be happy it isnt something that requires the bottom end to be removed or such.

LOL, true very true , only hope it corrects the problem ? have a great day !

**Butch2000** · 04-14-2010, 09:44 AM

OK , HERE WE GO !!! cam sensor was the problem all along , geeeez , so the 98 cam sensor reads different then the 99 cam sensor , this was causing my no start problem after the motor change , thanks to everyone for the feedback , this site rocks !!
