Toyota Repair: 1988 Camry Cam timing marks, fuel pressure gauge, crank pulley

Question
Ted, I hope you can help me. I broke the timing belt on my 1988 Camry 3SFE. I set the crank to 0 (TDC) using the lower timing cover mark. The Haynes manual shows the cam mark as a punch mark and has it positioned at 12 o'clock. I find the punch mark at about 9 o'clock. There is a half-line at approximately 10:30. The half line seems to align the distributor rotor with the #1 plug wire. This is where I set it. The motor will start but will only run for about 5 seconds. It seemed like it was not getting enough fuel. I checked the pressure regulator vacuum line and smelled fuel so I replaced the pressure regulator. It now runs for about 20 seconds. If I hit the accelerator it dies immediately. It runs a little bit longer if I take the electrical connector off of the plug under the throttle body (the ISC?). I do not have a fuel pressure gauge so I haven't checked that yet. I was thinking that I may have a fuel system problem but, after reading some of your responses, I think I may be a bit off on my timing. You indicate that there will be problems if you are one tooth off. I'm not sure how exact the crank setting is when you use a mark on the crankshaft timing pulley and an embossed number on the lower timing cover. Any advice that you can give me will be very appreciated.

Answer
Makes sure the engine is at the number one cylinder at top dead center with the crank pulley lined up with the zero mark on the cover, the cam pulley has a small hole in it, this opening must be lined up with a matchmark on the front camshaft bearing upper housing, you need a mirror to look through the hole to make sure the hole in the pulley is lined up exactly with the dimple mark in the cam bearing housing with all the slack out of the belt and the tensioner tight.
