Hello there I’m trying to get my 2002 4.0L V6 Ford ranger running good. This truck has 277,000 Miles on it as of right now it was leaking oil so I changed the oil pan gasket and the oil filter so that’s not leaking anymore, I also changed the air filter. After I changed all of that I thought it would be running a little better but when we tried to get it to start it started a little funny and we had to crank it a few times, we let it run for a while turned it off and re cranked it same issue it didn’t want to start so we stopped there. I asked my friends dad who knows a little about fords and he said it could be because we changed stuff but it still has a exhaust leak so im just coming here to see what you think.
