I’ve been going at my 1992 Volvo 940 non-turbo Regina/Rex system most of the week.
Problem started Sunday when on the way home I lost power and the engine wouldn’t go past 1200rpms, wouldn’t accelerate and couldn’t get to more than 15-20 mph. I had to pull over, at this point I could start the engine but couldn’t go anywhere very fast, then it just wouldn’t start at all, as of today it starts for a second before giving up.

Ive found that the injectors arnt getting power, none of the inputs read 12vs when key is turned, after cranking I pulled the spark plugs and they were bone dry.

What I’ve checked:
Crank position sensor works
Radio suppression relay works
injection system relay works
Fuel pump primes
Fuel is getting to the fuel rail
I have spark

Ive been all over the wiring diagrams and I’m stumped, any sort of help is greatly appreciated

 

You have fuel, you have spark, how about air. Is the throttle opening?

 

Yes the throttle is opening, my main issue right now is trying to figure out why the injectors arnt getting power
