Check the crank sensor !

no the fan is a clutch it free spins

Did you check the computer for trouble codes ?
Did you by chance move the crank sensor ??

Do you mean that the engine will not fire or run? If that is what you mean, When you replaced the clutch you may have damaged the Crank shaft position sensor. It is located on the passengers side of the engine. where the Bell housing and engine block are bolted together, Just above where the exhaust manifold and exhaust pipe meet. It is bolted to the engine block with 2 bolts. If you do not know it is there and even if you do it is easy to damage.

Check fuses to see if there are busted ones. Then check heater plugs if good. Heater relay included in check. Engine wont fire if the air inside the chamber is cold. Then check fan belts for wear, replace if necessary.

There are several reasons. The oil viscosity can make a difference and if the oil is contaminated with fuel. Wear in the oil pump and all of your bearings starting with the main crankshaft bearings and the connecting rod bearings. The wrong or bad oil filter.
When cold oil flows it plugs leaking bearings and oil gears. When the oil warms, the wear in the bearings (gaps) can't hold back the thin oil and the pressure drops. If the bearings are replaced before the crank and cam are damaged, the pressure will be maintained.

You need a new engine. There has been quite a few cases of rod bearing failures on these engines. If the engine is left idling, the oil pressure drops as it gets hot and thin. If there was significant wear already inside the engine, that wear would accelerate rapidly with low oil pressure and the bearings would spin in their saddles.

There is a clutch safety switch under the dash. When you press the clutch it presses the switch. You might try replacing that and see if that fixes your problem. This would cause it not to start and everything would still come on.

Sounds like you accidently pulled the thin wire from you starter motor. Look at the connections at the end of the solenoid, mounted on starter motor.The thick red wire is Battery + next to that connection is a smaller male push- on terminal, locate loose wire (thin) in the same area and reconnect to male push-on terminal on solenoid or check if earth cable between body/battery to engine wasnt removed in the process.Also some vehicles you have to engage the clutch before starting, check for a switch located on clutch pedal where master cylinder connects to clutch pedal (Is clutch switch mounted and wiring connected?)
