Did fuel pressure test idle running but not driving need to find a longer hose also checked every spark plug with plug tester and all is well there man this is frustrating oh and fuel pressure stayed at52 for awhile before going down 52 at idle and 61 when wide open
The problem is back starts right up a slightly rough ideal can drive it erring until I try to give it a little more throttle then normal and states missing
asking for help with missing back fire on my 97 gmc Yukon
370,000 miles 4x4 tried new fuel pump and filter no help also there is no engine light coming on. Fuel pressure is 50 to 55 . My next move is to replace plugs wires and cap .
It starts up perfect and ideals prefect and while in...
I'm having similar issues and I've tried everything. I have a 4 door Yukon and all my doors lock just fine. Only three of the four unlock tho. The drivers for does not unlock. I've changed actuator new wire harness from door to cab. And have tested all the wires. Multiple times. Very frustrating
Now I'm thinking it could be it only happens when I'm low on fuel. It started again this morning then it was getting worse I stop got fuel now it's fine.
It's the temperature sending unit I just bought one today cuz mine is doing the same thing. I took a wire from the negative to the connector just to test my gage to see if it was working fine and it is.
First of all the insults came after this guy well was being a better than you and your stupid in so many words kinda dick.
Soooooooo yeah I'm gonna say something. Anyway truck is running like a champ again for no reason just stopped misfiring. Probably because I had a long talk with her. Anyway...
Hey bro go back and read the post it says that there was a fuel leak. And the mileage is also there. So before being a dick you should make sure what you're saying is all 100 % correct. So since you aren't sure and you want to be a dick I don't need your ******* help.
Well it ran fine. Then I had a little fuel leak. I broke the plastic pulling the hose off the pump. Had to buy new pump and also got a new filter.
I don't remember the brand of distributer or plugs and plug wires. It's been probably around 5 to 7 years since last tune up. Wouldn't you think...
97 gmc yukon 380.000 miles. 4x4 4 door
Changed the fuel pump idols fine but when you give it gas it starts to misfire and sputters real bad. What to do now?
Today I was looking under my truck and noticed one of my end links was gone. Wtf wouldn't I have noticed when it came off?
I did notice that it wasn't driving very good on the freeway. I can't believe it's gone not broken hanging there just gone. Smh
I'm going to go down the list before I change it out. From fuse, relay, pressure and filter but by the sound of the pump im going to replace it's anyway just to be safe and the filter of course. Thank you everyone for your time and comments
Yes had fuel and the pump is allot lauder then normal. Sitting in truck right now and it started right up. There think is I don't want to get stuck so I'm afraid to drive any distance. Think I'll just change the pump today. Not looking forward to it but it has to be done
Yes gray and I painted most of it with got lucky and found black seats in junk yard and did the hardliners and carpet it's allot different now since it's been awhile lol
