Running out of things to check

I was comming home last sunday in 88 TC motored bajabug, coasting down a hill and when I got to the bottom the motor was still running but I had no power. I pulled off and stopped and restarted the motor and limped on home at a best of about 30mph. I live at 6800 ft and it's been below freezing here and now it won't start. I cranks and coughs but will not keep running so I can't get it to operating temp.

I've checked everything I can think of;
fuel pump is putting out 75 psi
plugs are firing and are wet
pulled codes; 21, 24, 28
21 ECT checked out good, it's below freezing here
24 VAT I checked the temp leg of the vane air flow meter and w/o any values to go by, it changed resistance when heated w a blowdryer
28 also comes on below 50F
I checked the timing belt and it looked worn and loose and thought it could be the problem but I think the timing marks are lined up. The Haynes manual I bought says nothing about timing and the pictures they show of the timing marks are poor. So I think they are right but not sure. When cranking, my timing light shows about 20 degrees ATDC. That seems OK for startup in the cold but I don't know for sure. I've checked the TPS and ACT. Is there anything else to check?

A fuel pressure of 75psi seems a bit high. Is this at idle or what? You should have 39-40psi at idle w/ the vac line disconnected. Check your regulator.

timing should be about 20 degs btdc,sounds like it shiped two teeth on the acc drive and lost 36 degs.

75 psi is out of an aftermarket pump that was read before it got to the fuel rail. I am getting wet plugs and smell of gas when I try to crank it. I am also headed to town today to pick up a new timing belt, while mine was not missing any teeth it's in bad shape (has cracks) and I thought it was loose when I first checked it. Before I do that I will try to imporve the timing.


The timing was off, she cranked right up after some adjustment.

I found the timing spec on a search of the forum, what's with not having that timing info and procedure in a Haynes manual?

Thanks for the help.
