crank angle sensor


Recommended Posts

Thanks...I wasn't getting fuel and the fuel pump wasn't staying on when I tried to start up the engine. I have a 89 GL wagon with Turbo 1.8L EA82 engine. It was having a hard time starting. We replaced the fuel regulator and cannot get the thing to start.

 

Reading in the Haynes manual for MPFI fuel pump continues to run when cranking and running providing ECM receives reference pulses from electronic ignition. If no pulses pump will shut down as mine does.

The CAS in a 89 EA82T distributor

controls not only the fuel pump via the ECU but it also

controls the spark.

 

From your post it does have spark.

 

Therefore I would say the CAS and the ignition amplifier are working.

 

Have you verrified the pump is running when

the key is in the crank to start position?

As a folow up

It occured to me that I had an EA82T distributor

laying on a work bench.

 

I took the cover off of the sensor ring and found

there appears to be two sets of slots

one inner with four large slots and then the outer

what look like 360 slots (one per degree)

 

So it is possible that your CAS is having issues with

the pulses coming from the four inner slots.

 

I appologize for the mis information.

The only test I know of, barring the use of an occiliscope

is to try a know working model.

Thanks Skip...Great Picture.

I went out and made sure there was no tension on the distributor cable. The fuel pump continued and she fired right up. I am going to let it set for some time and start it again to make sure I've gotten it.

 

I bought this a year ago from a guy who bought it from a backyard mechanic who put a Japanese exchange engine in it. Neither of them could get it to work. A primary vacuum line was cracked and taped. I replaced the line and what a difference. Corrected the timing 90 deg out and she a go'n little thing.

 

I have several junkers and I pull parts to keep these things running. I like working on the Subaru.
