Unfortunately I jumped the gun everything was dunning great until just a few minutes ago. Just went to start my jeep and it would just crank and crank until I pumped the gas. It was starting so much better after cleaning the throttle body too! I'm honestly not seeing any patterns here. I still think it might be fuel pressure related, but it started immediately this morning. I let her dit for 4 hours after work and now I sometimes need to pump the gas to get her to start. Any other ideas? Could it be the throttle position sensor? My next step will be to check fuel pressure at the rail. That should tell us if its pressure related or not.
Yes, yes, and yes. Car still starts ok but I have to pump the gas while cranking to get it to start. I can hear the fuel pump prime as well. I regularly have been priming the fuel pump two or 3 times before starting the car, but so far, that seems to not help. That is why im starting to think throttle position sensor or crank position sensor. The symptoms I am seeing are kind of all across the board. Thats why I am thinking fuel pressure would be a good place to start? Then we can determine what the next logical step would be if its not fuel pressure.
Sorry, havent had the time to check the fuel pressure. in other news though, the fuse hasn't blown and I havent had any issues starting my jeep. I did notice though that cycling the key about 5 times for 2-3 seconds would build pressure and the jeep would start fine. But when I just left the key on, I could hear the fuel pump prime but switch off after about 2 seconds. Not sure if that helps any. I know the next step is to check the pressure at the rail. Im hopefully going to be able to do that either today or Thursday.
Que! Sorry, its been a while since ive updated the thread. I am fairly certain my fuse that blew previously was just a bad quality Chinese fuse. Jeeps been running good. I rented the equipment to test the fuel pressure and hopefully will get to that either today or tomorrow after work! Thanks again for your help
