Where is the compressor/clutch cycling switch

There are low pressure and high pressure switches in the system. One is usually on the back of the compressor, the other is in one of the metal ac lines or at the accumulator.

Im trying to get the starter off my 94 camaro and I got the two bolts out and the wires unhooked but im having great difficulties getting it around the Y pipe and the two engine coolant lines.

i had same problem, it took two sets of hands though. we took a long screwdriver n put just a little pressure on coolant lines, turned starter so solenoide is facing upwards toward sky n pull it toward back of car pulling nose out then apply very little pressure with screw driver to coolant lines n it should slide out, jus be very very careful with coolant lines!!

Our cadillac will shift into 3rd but wont shift out of third.

Hi and welcome to FixYa!
I pressume that you have a manual transmission. If that's the case, the clutch lining must be worn out that's why it doesn't shift out on third. I strongly suggest that you replace the clutch lining, pressure plate and release bearing. This will surely resolve the problem and a smooth shifting will be noticeable.

Hope this helps and thank you for using FixYa! Have a good one!

I have a 1994 Sedan Deville that cranks longer then it should on first start ever morning. It starts good the rest of the time. 4.9 liter V8

fuel pressure is probably bleeding off when it sets for a period. it probably is bleeding off into the return line if you see no leaks.turn the key on for 30 seconds then off before starting. if you dont like this then you can replace all of the fuel line o-rings in the system and pressure regulator/fuel rail assembly

Cant start 94 cadillac elderado

Check fuel pump pressure and fuel pump regulator. It sounds like you are not getting fuel into the system and if you are you are not getting enough fuel into the system

I TOOK THE GAS TANK OUT TO FIX A BROKEN GAS LINE. NOW It pumps gas to the fuel pressure regulater but nothing past that nothing in the fuel rail it ran before I took the tank out.

Some how you have the pressure and return fuel lines backwards. Double check your repair,I am thinking you cut atleast 2 lines for the repair. Just reverse them.
