924s no start

[S15508g]

OK so my 87 924S is not starting.
I changed the dme relay no change
My fuel pump is receiving power When I crank it. It does turn over
I took the fuel line off the rail and it is pumping gas to the rail
The injectors are not firing
I have spark It did run before I parked it
The injectors do click when I put 12 V to them
I checked My speed sensor and reference sensor it does give me good ohm values between the first two pins of the sensors
But no ohms are detected between the two outside pins on both. Where it’s supposed to read 1 million ohms its reading an open circuit. I ordered both of the sensors
It did run a little rough before putting it away maybe one sensor was working and now both of them are not my guess? Battery has lots of power. Try the new sensors when them come in or does anyone have any ideas. Even if the injectors were clogged there’s no way all four would be. Plugs are dry don’t even smell like fuel. There is a good video about checking the Crank sensors on YouTube just seems odd that both sensors go

Oh my God I can’t believe I got it running the fuel injectors were stuck. I took the injectors out and gave them a quick little clean I can’t believe all four injectors were clogged Craziness

I remember trying to look and observe the spray in my volvo. it wouldnt spray until I realized that I had a ground wire that Id pulled of , it was a black wire that goes on a bolt holding the fuel rail in place.

glad you solved it, I wondered of perhaps you had inadvertently fixed a ground issue when cleaning the injectors. in reading, I figured it could explain why they appeared to all fail at once.

The only times my 944 has failed to start in it's entire life is when the battery is dead, and the one time it sat for long enough that all 4 fuel injectors were stuck. It's started with one stuck several times, and even with 2 stuck a couple of times. They free up after 10 to 15 seconds. These days it is started or driven enough it no longer happens.

Congratulations on being up and running.
