so i have a 91 yota 22re time recently done and a new starter. throwing codes 3 and 14 witch point to ecu and igniter. any one have simlair problems? it cranks over sometimes but does not start or dosent even turn over. i can hear the computer click when i turn it over though. any one know of any companys that rebuilt your ECU??

 

You need to determine if it is the Circuit Opening or Starter relay that is activating.

Might want to double check those codes, I was nder the impression they ditched the single digit codes to avoid possible confusion.

The error code list on 4crawler's site says 3&14 are the same thing. No IGF signal. Likely cause is the ignitor, or just a loose connection somewhere.

Same goes with the starter, assuming the relay is good and activating, probably just a loose/fouled connection.

Were you haveing the no crank issue before the replacement starter was installed?

No help on the computer sorry, I do know there are some aftermarket ones for tunable injector maps..

 

I would not go getting a rebuilt ecu just yet.

I would look long and hard at your ground cables and make sure the one on the manifold for the ecu is tight and clean.

there is a company that exchanges or rebuilds them I would guess they do Toyota but not sure.

If it goes that far PM me and I will check.

 

thanks guys. i was looking for the ecu ground for while couldnt find it. let yall know what i find tomorrow.

 

bump
Still nothing. replaced starter relay and checked my grounds they all looked good. idk whats going on with it. one day she was running great then the next day she was dead.

 

Just how did you check your ground cables??

It sounds like you have maybe two different problems.

Let us get the vehicle to the point it cranks every time you turn the key to start.

Is this a manual or Auto?

Once you get it cranking every time you can then check the coil and igniter to see if they are a real issue.

 

its a manual.
i just took the grounds off and check to see if off the wires and connectors were good.
when is was turning over i was getting spark.

 

got it to turn over no start now. maybe jumped a tooth? i just did a timing job on it less then a year ago.

 

Let's agree on vocabulary: "Turn over" means the engine spins. "Fires" means you can hear one or more cylinders firing. "Starts" means it will run on its own (no playing with the throttle) for at least 15 seconds. "Idles" means it will run continuously (maybe not very well) at less than 1800 rpm with no load without stalling. "Runs" means everything is okay.

Does yours fire? Are you still getting code 3 or 14? If you're getting codes, you're probably not firing the plugs -- check them with a timing light (that's the easy way; if you're really tough and not too smart you can hold a plug against the block and look for a spark). Do you have fuel? Are the plugs wet or dry when your remove them?

You probably didn't "jump a tooth." That's just a myth.

 

in total agreement on the vocab. its turning over. not fireing no start no idle no run. haha

just replaced my plugs. i dont have a timing light. once my room mate gets home im going to check my plugs again to see if i have spark. and i am deffenitly getting fuel.

 

no codes now. its just giving me the intermittent flashing check engine light.

 

There are only two codes that don't get stored in memory, 51 and 53, and 51 doesn't turn the light on.
