03 Malibu cranks but won't start ( not a passlock problem)

Man, it's obvious you know WTF you are doing and have done everything right. But may I ask..overheat...how hot did it get?

It red lined and cut off on my way home after buying it for $400 only happened once and it was toed the rest of the way to avoid blowing a gasket

Towed*

Check the timing?

Wouldn't a timing issue set off a code?

Nope.

Yeah timing occurred to me but pump is not inside timing cover, unless you mean ignition timing and he did change crank sensor,

When it ran hot,may have heatedtiming belt,causing belt to strech and jump.Not my first time seeing this happen on a malibu. You replaced pump,now want start.Check the timing.

Yeah timing occurred to me but pump is not inside timing cover, unless you mean ignition timing and he did change crank sensor, Cam sensor does injector timing, crank does ignition timing

But good point TST

OK thanks I'll check

But a bad cam sensor will throw a code

I had the same thing happen to a 2001 malibu water pump went bad,car ran hot,replaced pump,car would not start,and gave no code,s,i checked timing,and it had heated belt,and jumped two teeth,i was lucky no head damage.

On the 03 Malibu it has a timing chain not belt so there's no stretch

Good,glad yours, had chain,since that is not your issue,then check for fire.Then check fuel.IF you have both,you may have head damage from over heating.

If it cut off when over heated,check compression ,this will let you know if you have head damage.

That's what I was afraid of well at least it didn't cost me much. Looks like I'll be spending Saturday taking the engine apart. Thanks for the help
