So broke down on my wife 2.5 years ago. Had a buddy run code test bout a month before as little things popped up. Long story short everything started after a mobile/home business mechanics test showed bad fuel pressure and resulted and a new fuel pump. Over the next week or maybe 2 weeks after vehicle starts running funny and codes pop. Range from the 02 sensors bad, misfiring spark plugs, the spark plug wiring being bad, the fuel filter clogged/needs replaced. So then I proceed and change out the fuel filter, change out all 4 o2 sensors, change the oil, replace every spark plug even though that I just did a tuneup n replaced them a month and a 1/2 ago, brand new spark plug wiring.

So I had no choice because it was the only running vehicle at the time in the house but still wasn't running a 100% right went down to deer camp and over that weekend the truck ended up going down. When I got back went to the truck started it up salad and a rough with a new ease in the engine that I can't really figure out then a son of the wife's coworkers who works at a dealership as a mechanic came out And he did the ear test with a long bar and he conspicitur the state what is she was just knew that from his thoughts the noise was coming from the bottom of the engine. So he recommended the fact that pay it could be the fact that your each year valve is after up any need a new one and it just needs the drip some oil down there and a could possibly take care of that but he wasn't giving his expert advice for working at a dealership just a recommendation so even though that I did that the engine can I went to cramp. Can really start to keep the engine running whether rose the battery or the engine just didn't want to go anymore. Cuboids later got towed that I inhabit towed back to my house in haven't really dealt with that sense because been saved up been trying to get money together to take her cousin's kind of sentimental value to me. But after doing all that the fuel filter the oil change new spark plugs spark plug wiring each year valve fuel filter fuel pump 02 sensors everything else in the new EGR valve what is the whole issue that could possibly be causing it that it will not runner basically candidates bogs and shuts down when trying to initially drive it.

Hello, I'm Danny.

You mentioned you replaced the fuel pump and fuel filter. Can you perform a fuel pressure test to verify the fuel pressure? Here is a tutorial showing how to perform a fuel pressure test:

After performing this test get back to us with the results and we'll go from there. The fuel pressure specification is key on, engine off or engine running 30-40 PSI for your vehicle. Hope this helps and thanks for using 2CarPros.
