What up everybody,
okay a few days ago my car started bogging down as soon as i would shift into third and wouldn't let up until it was over 1700 rpm. i looked around here and among other things, saw that the problem might be in the fuel filter or pump, so i thought i would replace the filter and see what happened. One of the steps to relieve the fuel pressure is to remove the "fuel pump" fuse and run the car until it dies. I have a '92 RS 3.1, and in the fuse block there is no "fuel pump" fuse only INJ# 1 and INJ#2 so i pulled those out, because in the 89 model INJ 2 was also labeled F/P. The fuel pump still buzzed away, but with the 2 inj fuses out it of course wouldn't turn over. I replaced the fuel filter and triple checked to see if the flow was the right direction and also changed the plugs since it was a nice day and all the tools were out. When i put the fuses back in and tried to crank the car, it would do nothing but turn the flywheel and not start up. I checked the pressure relief on the fuel rail, and it's getting gas, it's also getting spark, so i'm at a loss. Any ideas why it won't crank?

 

Sounds to me like it's cranking, just not starting.

You need to determine if the injectors are pulsing. I'm not SPFI-literate enough to tell you how to do that.

Have you pulled a plug to see if it's wet? If it is, you are getting fuel to the cylinders, but perhaps not the right amount. Or, the spark isn't getting there at the right time.

 

yeah i pulled a plug and it sniffed of gasoline, and felt wet too. I'm not really sure how to adjust anything for this engine. All i know is i pulled some fuses and put in some new parts and now it won't start.
