Couple cranks to start.
Car is a 92 RS 305 TBI. It was running really rough today, so I checked the codes and got a 33. Easy enough, bad MAP sensor. Replaced it and ran alittle better. Decided to put in new plugs, and an o2 sensor. Got the car running pretty smooth now. Only issue is it takes 2-3 cranks to start. Tried to listen to the fuel pump prime but couldnt hear it. Is it starting after a few cranks because its seeing oil pressure? That would point to what a fuel pump relay?
We did put in a new fuel pump, fuel filter, and I believe a fuel pump relay two yrs ago.
EDIT: So the fuel pumps priming its just really quiet. Can anyone tell me the spray pattern for the injectors? When cranking theres an initial spray, then what seems like a pause for a good amount of time, followed by a regular pattern.
