99' Galant 157k with Recent Starting Problem Issue

RE: 99' Galant 157k with Recent Starting Problem Issue
Just replaced timing belt, water pump, tension-er, idler pulleys and crank sensor, valve cover gasket, on a 1999 Mitsubishi Galant 2.4 L SOHC

Belt had stripped around crank gear at reletively low rpms (i think) maybe even when just trying to start after running an errand. Came out and car wouldn't start, no signs of trouble before parking

anyways, here's where I'm at.

Put everything back together and started vehicle -it runs but shows 3 codes according to oreilly auto parts (po100, po105, po110)

Since this is an interference engine, still wondering whether I have bent valves.

Questions: If the valves were bent would it run at all?
Can you tell me what these three codes together might mean? (indicate)?
Where can I find info on these or how should I go about troubleshooting from this point on to make sure I'm good to go?

Any help is greatly appreciated

If it runs without a skip and seems to idle ok you can consider yourself lucky. If you want to prove things out then do a compression test. All should be similar readings within say 20 - 30 psi. That will verify the engine itself is ok.

As for the codes, I suspect you set some of those during diagnosis or forgot to hook up all the vac lines, air filter, etc.

P0100 = Mass Air Flow issue. (intake boot off?)
P0105 = Manifold Air Pressure. (usually low vac or a line off)
P0110 = Air Intake Temp. (sensor disconnected or malfunction)

After looking things over you can have the codes cleared and see if the light stays off. If the engine light comes on again then you still have a lingering problem.

Edited to add: Always repair / diagnose the trouble codes in numerical order as the first one is most important and will sometimes help solve one that is a higher number. IOW, if you tried to start the engine with the intake assembly laying on the bench then reinstalling it and connecting the wires will likely fix P0100 (MAF) and P0110. (AIT)

Got the codes OFF and just got back from a 30mi test drive and no codes .

Yet noticed the power steering pump squeelin ad puking from the top seal cap.

Opened the cap and see frothing air pockets , attempted to completely drain the fluid and refill and still seeing air in the line.

The air in the PS fluid will go away if you shut the engine off and wait a few minutes. On some cars it may take jacking the front wheels off the ground and turning the steering wheel lock to lock a few times, then let it sit with the engine off for a few minutes. The air will eventually rise to the top.

Glad to hear you got the rest under control!

Hopefully the code will point us in the right direction. It is going to boil down to, "What did you loose?" Either there is no "Spark," or no "Fuel." Once we know what is missing we can follow the path to "Why" it is missing. Shooting in the dark, sounds like the coil.

Post the codes here and we will try to provide some better information.

Thanks for using the forum,
