Asked by Aug 13, 2014 at 09:58 AM about the 2003 Chevrolet Malibu Base

Question type: Maintenance & Repair

Ok it ran perfectly until it started overheating
so I replaced the water pump ( pain in the butt)
and t-stat, after I hooked the battery back up it
cranks but won't start.  I've put an obdii to it
and it has no codes the anti theft light is not
flashing. Fuel pump and filter are new , I have
fuel at fuel rail port. I've also replaced spark
plugs, spark plug wires, ignition switch, ignition
control moduel, crankshaft position sensor. I'm
at my Witt's end it should start but simply
won't.

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.

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
