1) And the brake lights are on non-stop...

2) The car is not getting a spark

I think the guy who sold me the shell messed with the dash and body harness???
Or is this a common thing....

someone please help me find the problem

fyi: I just finish wiring a sr20det s14 motor into it...(ordered a video and double checked all the wiring)

Brake lights I'd just trace the wiring from the lights back to the pedal & fuse.

Regarding the no spark... Do you have fuel pressure? Are the spark plugs wet? Check these two things ASAP, they tell you why you don't have spark. If there is good rail pressure then you know the fuel pump and relay are wired correctly. If the plugs are wet with fuel then you know the injectors are wired properly and are firing. If the fuel injectors are firing, that means that the CAS is working properly and you should look at your ignition circuit. But if the fuel injectors are not firing (dry plugs) then you either have a problem with the fuel pump circuit OR the CAS circuit... Remember the CAS provides signal that is used for both spark timing and fuel injection.

.....OR the little rubber/plastic grommet that pushes the brake light switch. I have owned two vehicles that just did the same thing and brake lights just stayed on. That little plastic was the first thing I had checked and found the pieces on the floor.
