Question Car turns over but sounds like the timing belt is broke. Timing good ???? HELP PLZ.....

I have a 2004 SVT Focus. It has ran great up until today. I went to start my car and only cranks over. It sounds like the timing belt is broken as the noise sounds to have no compression. I pulled the timing belt cover partially back and the belt is tight. Pulled the valve cover and tried to put in the flat bar in the back of the camshafts and it fits in correctly, which shows the cams are timed correctly. I did not strip the side cover down to check the crank, but it appears to me the timing is correct. I have no codes in the system. The car has shown no issues to this point upon parking the car for the weekend, the oil is at the correct level and fairly clean. The engine has 69k miles. I do not see any visual issues with anything. Any ideas on where to start?

Well an IDEA would be do a compression check if it seems like it has none. If so, then maybe your valves are just the tiniest bit off somehow but open on the compression stroke enougt to disallow combustion.

BUT FIRST... You're not holding the gas pedal to the floor when you try to start it do you? That cuts off fuel flow. I've done it a few times and it's a pointless PITA LOL.

does it just sound like it cranks and cranks and cranks? When my coil pack pigtail went bad, that's what my car did.

I am not touching the gas pedal at all. I will check compression tomorrow night to see what the readings are at. The engine just sounds like a sewing machine at this point, but is not turning over extremely fast. It has me stumpt, from my experience the noise sounds just like a car having a broken timing belt. I do not have much tools with me at this point to test much out, I am looking for some ideas to get an idea of what I should be looking for and what tools I will need to get to find the issue.

Have spark. When I was checking spark, the engine had a split second where it sounded like it was going to fire. Will check for fuel tomorrow, I replaced the fuel filter at 49k. At this point as far as fuel goes all I know is that I can hear the fuel pump working. I have not inspected the complete timing belt at this point as I am not sure which way to go with diagnosis.

When you put the timing bar in the cam ends, did you see if you could insert the timing pin in the crank as well?

Checked the whole belt and no missing teeth.

Did not insert the timing pin yet as I have not tore down much to make it to that point. Is it fairly easy to install the tool or what am I looking at? I may have to check out the manual to get an idea.

No missing teeth. Mine sounds similar but has a slightly higher noise and spins a little slower.


At this point I know I have spark, belt is good. Cams are aligned. Have spark and fuel. Compression on #1 @ 80 PSI / #2 @ 75 PSI / #3 @ 80 PSI and #4 @ 60 PSI. #4 has me a little worried, also notice that the oil on the #4 intake valves is very little compared to the others.
