i have a 95 blazer changed fuel tank fuel pump sending unit fuel lines spider and fuel regulator and fuel filter.It will just crank for 5 to 10 sec until the oil pressure gets to 20 then starts right up. I was thinking there is a rollover switch or something that is bad but can't find any info on it.
Runs great just wont start till 20 pounds of oil pressure.I dont hear the fuel pump at all when i turn the key over to try to prime it.Just have to crank it till it hits 20 pounds oil pressure then starts right up.It is quite annoying any help would be much appreciated thank you
