Unhappy TIMING BELT CAM MARKS PT CRUISER 02

i just had my head rebuilt, and now I'm putting it back together. Ive never done a timing belt before, and I'm a little worried I might get this all back together and it be wrong. I had a time lining the cam and tdc marks up. the cam marks are lined up now, but they literally look like they are a hair between the two. the crank was on the trailing edge of tdc. i did a compression check on all 4 cylinders. the readings were between 180-185 consistent. i think if it wasnt right then i wouldnt get that high of a reading and it wouldn't be consistent either. let me know what you guys think. please, thanks jon.

There is a step by step how to in the tech section at the top of the page. Also have been a bunch of pictures of the line up procedure. Also you will want to fire it up before you put all the way back to make sure it run right. Real easy to be off a tooth.

Under the Tech & Performance section of the forum we have a tread entitled HOW TO. Here's a direct link. There's about 4 threads inside that one that deal with the timing belt.

use a straight edge thru center of cam bolts- otherwise they can look lined up but not be.

you can start it before you put everything back together

Ok, Im back. Thank you guys for the info and advice. I double checked my marks and my compression,,,,, all were consistent. I now have another problem. I got everything back together and went to start it, but now it wont start. It turns over for a few seconds, but then stops turning completely. It never starts, fires, backfires, or anything. If I turn the key back off and try it again, it does the same thing. I can hear the fuel pump running non stop. I bled the fuel system at the valve on the injectors rod, and it seems to have all the air out, and plenty of pressure. One thing maybe not worth mentioning, is that the tach gauge goes all the way over, and the display shows the cruise come on. I've unhooked the battery, removed the fuse to the fuel pump, but still the same after I hook it back up. No start at all, and the fuel pump continues to hum in the tank. I also sprayed starting fluid in the throttle and held it open while trying to start it, but no luck. Everything ran fine when I parked it to work on it, so I don't think anything new is broke. I feel like it might still have some air in the lines, and the pressure is not building up, thats maybe why the pump continues to run.... but i don't know. Any ideas???

The pump is a 'dumb' system- It works without regard for pressure.

PCM does have a feature that shuts it off if it doesn't get a crank signal*

Sounds like you didn't connect something or got the timing off.
It will run on a bit of ether, so that should rule out fuel as an issue

Didn't disconnect coil and cam sensor by any chance? same plug, same area

yes i did disconnect the cam and coil. I had the head rebuilt. I thought I connetected them back in the right spot. I'll double check that. I sure hope its that, and not the timing. If the belt is off time then Im taking it somewhere else to get it fixed. I am deffinitely not a mechanic, lol. thanks for the info. I will let you know how this turns out.

after you cranked it over a few times, spin the engine over by hand and "recheck" the timing. if you did as i did with swithing the wires you will most likely have to change the PCM. just another free $0.02 i will offer for you!
