Thanks for posting
Was it running ok before replacing the headgasket?
Have you checked for injector pulse voltage yeat?
Any diagnostic codes in the computer?
Thanks.

It quit on the road with no fuel pressure. I started with replacing the pump and now there is pressure. A 17 year old was driving it when it quit so little info. I have checked injector pulse and it is present. No codes at all. I'm an experienced mechanic but I'm missing something somewhere.
Customer reply replied 3 years ago
When it didn't start after fuel pump replacement I started checking it out and found Timing was off about 8 degrees and compression was 30psi on two cylinders. That's why I did the head gasket and timing parts.
Customer reply replied 3 years ago
The driver said he started to pass a truck and it started running rough, pulled over and cut it off. Hasn't fired since. I picked it up with a dead battery and brought it home.
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
Thanks, ***** ***** compression was low due to burned valves on two cylinders and the compression is good on all cylinders now? Can you check intake vacuum while cranking the engine? I,m curious about what kind of vacuum the engine has.

Customer reply replied 3 years ago
Head gasket was leaking, all compression is good now. Vacuum is 16 in while cranking
Customer reply replied 3 years ago
I figure some of the compression loose was due to the stretched timing chain.
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
Everything seems to be ok, the problem may be the ECM, this may be why there are no codes stored, there is a recall in effect from Toyota for defective ECMs which can cause some weird problems, check the ECM part number, it's located below the glove box, let me know what the part number is ***** I'll check to see if it applies, the first numbers are something like 06991 followed by some letter and numbers.

I don't understand how I can have fuel, spark and compression and it not at least try to start. If the ECM is bad wouldn't there be no spark?
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
No, it's out of the affected number range. Not really sure what's going on with this engine, if there was an input sensor malfunction there should be some code information, a fuel delivery problem won't set any codes but you say it has fuel pressure and the injectors are working and there is spark, good compression and good vacuum and the timing is ok, this engine should run. Possibly contaminated fuel, water in the tank, someone put diesel fuel in, anything like that could be the case.

The fuel pressure is 45 psi while cranking, the pump doesn't run until you start cranking, is that right? Haynes book says it should come on with the key in run but I read somewhere else Toyota doesn't do that.
Customer reply replied 3 years ago
Fuel is clean, I checked all that when I put the pump in.
Customer reply replied 3 years ago
I've had the injectors laying on the valve cover and they all spray fuel.
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
The computer gets a crankshaft signal from the cranks sensor which causes the pump to run, after that the circuit opening relay keeps the pump running. It does not run with just the key on.I really don't have an answer for you and I have to go offline until tomorrow, you have the choice to opt me out and wait for another expert that may have an answer for you or re list the question, please do so without rating when they ask you to do so. If I can think of something else overnight I will reply to you tomorrow.

Coils are 4 wire, I have battery power to #1, 5 volts on #2 with key in run, #4 has zero resistance to ground.
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
The black wire to each coil should have 12 volts with the key on, the white/black wires are the ground wires and should show zero ohms or less to ground, the other wires are spark and timing confirmation signals to the ECM.

Ted, I actually figured it out this morning. The exhaust cam gear had sheared the alignment pin and it was off. Amazing it still had compression but was exhausting has it should be firing.
Toyota Mechanic: Ted Ritter, Toyota Master Tech replied 3 years ago
Probably was over revved when it quit running and I bet it bent some valves too which you already took care of, makes sense now.
Sometimes taking a break from a problem and re thinking everything helps. Good luck, we both learned something.

Pictures are worth a thousand words. I didn't find any bent ones or any signs of contact. It's running good. I'm sure it was rev'd high. Thanks for talking through it with me.
