Water pump needs replacement

Who did the water pump replacement? Replacing the water pump required the removal of the timing chain. If, during the removal and replacement of the timing chain, the camshaft sprockets were not doweled into place, they would need to be rotated to regain proper timing. If the crankshaft was not properly positioned when this was done, or was rotated too far or in the wrong direction, severe damage to the valves and pistons would have occurred. This would result in no compression and the vehicle not starting. I would pull the plugs and do a compression check before anything else. If the compression test fails, you need to pull the engine apart and prepare for some hefty expense for repairs.

You may have a bad relay. Have you tested it to see if it is working or have you changed it out with a new one?

sounds like a cylinder head gasket, check for coolant in the oil.....SORRY

You replaced the water pump i presume?Are all the bolt tighten to the correct torque?I just done a water pump replacement on a 97 Cavalier and i had one bolt loose and thought that i had misdiagnosed my coolant leak problem when in fact,i had just not installed the pump tight enough.Also,you may want to use silicon sealant instead of the supplied paper gasket,i've had better luck with sealant rather than the paper gasket.

No the water pump will not affect the smog test. You probably failed the idle?
Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.

Your fuel filter may need to be replaced or your fuel pump has gone bad and will need to be replaced. Check all your fuses and the fuel pump relay, if that all checks out good, then it's going to be a dirty fuel filter and or bad fuel pump and that is located in the gas tank. Good luck and hope it's a simple fix like a dirty fuel filter.

This is a job for the dealer or cerified mechanic. The front cover and timing chain needs to be remove to access the water pump mounted behind the engine. The pump is driven by the timing chain and timing will need to be reset using special tools.

What engine? Automatic or Manual transmission?

Hi well since i do not know what engine it has

2.2 liter the water pump is below the alternator not to bad to change

2.4 liter you will need a shop to do this and about 8 hours lab plus parts

have you changed the sensor on the coolant reservoir? try that.
