Topic: 22re no start help

[Tcyota]

I know this subject has been discussed but I couldn't find the thread when I searched. '87 Toyota 22RE. Getting fire, getting fuel, double and triple checked the timing. Can spray gas into throttle body but still no fire. I put an EFI relay on, swapped the ECU. Need help please and thanks in advance.
Could it possibly be that the valves need adjusting?

There are basically three things needed to fire a cylinder.

Gotta have a sufficient fuel/air mixture, gotta have sufficient compression, and you gotta have sufficient spark.


How did you test for spark?

How did you test for fuel?

Did you do a compression check?

Does the engine act like it tries to fire?

The valve lash would have to be way off in nearly valve for you not to be able fire an engine.

Did it suddenly not start or has some work been done to it before the problem?

MAF, Fuel pump? Idle screw all the way in? How did you check the timing without it running? Any codes?

One more Time By the Book. Properly timed Hot spark, Proper air fuel ration, Compression , And proper ? ??.
There are actually 4 things.
Fill in the blank please.

Well... the firing order has to be correct, right?  So, the plug wires will need to be in the right order from the disty to the spark plugs - 1-3-4-2.

Nope that's Part of the properly "timed" hot spark.
Guess again.

Well... of course the crankshaft has to have proper rotation speed, right?

My ASE Certification has expired!

Good Job Gnarls!

Good Job Gnarls! 

I just need some erudite injected certitude.     And...Tcyota needs some fire in his injected cylinders!

Checked fuel by cracking fuel line at the filter and at the cold start injector. Check spark by just pulling plug and turning motor over. Motor does not try to fire. I check timing by bringing 1 tdc both # 1 vavles was loose then check distributor

Ok I did a compression check it #1 showed 60psi the rest was less than 50psi. I traded for this thing not running and it looks like they have put a head on it. Don't know if it ran after the head was put on. I know that 60 psi is not good what could cause the low reading ? Besides just wore out need help thanks .       And my compression tester is new but from harbor freight ?   

[Tcyota [OP]]

Also put some oil in cylinders and it did not change psi much at all.

Well, I don't think 60 lbs is enough compression to fire the mixture.

Try adjusting the valves then check comp. again.

With engine at 5* BTDC, the dist, should look like pic #2 when installed.

[Tcyota [OP]]

I also checked the injector pulse with noid light and I am getting no fire to the injectors

[Gnarly4X]

Qué pasa??

I suspect the valve timing is off if all cylinders have low compression and oil made no difference.

How far off would the valve timing have to be to have low compression in all cylinders?

Tcyota,

Did you check the cam timing?
