Asked by Sep 21, 2013 at 08:37 PM about the 2004 Toyota Sienna 4 Dr LE Passenger Van

Question type: Maintenance & Repair

Car will not start. Cranks all day but never fires. Have checked fuel, thats good. Checked
spark, thats good. Intake system no problems. Took to dealer they said broken timing
belt. Pulled front of motor down wasnt broken they then changed story to it jumped timing.
Replaced timing belt and water pump. Also replaced crank sensor. Still will not fire. Im out
of ideas at this point. Any help would be greatly appreciated.

Do compression test to see if you have any bent valves. I believe your model is an interference engine and if so and it jumped time you might have some bent valves.

If you got the timing right...I would be stumped too

Ok did a little digging. Your compression ratio is 10.8:1 on that model engine. Your proper psi operating range should be 162 psi to 216 psi per cyl. Would like to see your psi to be within 5 to 10 psi of each other and on the top side of the operating range. Although your psi appears to be low on the front bank and varying greatly from front to back bank I don't really feel that its a bent valve issue causing them to be low. Normally with bent valves you will see some with 0 psi per cyl. In my opinion your engine should still start with the psi numbers you posted.

In the beginning were you driving it and it went dead or did you just try to start it one morning and it would not start? Was it acting differently than normal the last time it did start?
