Engine starts and shuts down

Use either of these to check fuel pressure. Disconnect your fuel line under the hood and this will connect 'inline' and give an outlet for your fuel pump. I have used the Dorman part but have the Nitrous part waiting to put in.

Nitrous express 16190 (you'll need a Schrader valve or other output to use this)

 

You checked continuity (ohms) with power on the circuit? AFAIK you don't do that.

 

mine wont start once about every 4 months. it will start after ten tries. I was thinking it was the key chip because my key is so lose it can fall out while running. but the other day when changed my spark plugs, 2 of the coil bolts were totally loose , coil could move up and down or no grounding???

 

Update....Good info fellas. I replaced the relays...no more trouble. Knock on wood. Thanks for the info. I also fixed my wifes town n country.....i went out for a carton of smokes and came back with a 2013 Corolla. Lol.

 

And that good sir it how you keep a wife happy.......Well played!

 

The saga continues......the problem is back. so. I picked up the pump. I had trouble droping the tank so I removed the bed. Should have the tank back in today. While the bed is off I plan to look for a cpl noises back there. One is probably a brake drum. the other I hope to be a universal joint or center berring. Also gonna add D rings to each bolt n the bed floor for tie down points.

 

To right 906. Shes very pleased.

 

My gmc yukon has a built in security that has left me stranded when jumping the battery, it thinks im stealing the truck and proceeds to not let me start truck. Have to wait for about an hour for the "theif" to leave

 

that is another possibility

 

one bad berring in my rear most uni joint. not a single roller berring in the cup.

 

Well vibration and noise was fixed. With the new pump....she started up and ran. I shut down and tried to take it to top off the gas tank and it ran for 2 sec and sut back down....same crap its been doin. For now I am gonna asume its air in the fuel line. It runs like a raped ape now.

 

I've had this issue a couple of times. It has acted up on me twice but hasn't in a long time

 

If it turned on then off after disconnecting the battery that's normal. If it does it more than once it's not. It will start and stall 1 time usually after the battery is reconnected.

That being said if it's still doing it and it's doing the starts for 2 seconds and stalls maybe look at the battery wire / connector supplying the ECM. Normally I wouldn't go there but you have no CEL, have replaced the fuel pump, and relay. Maybe there is a bad or corroded connection and the ECM looses its memory almost like you are disconnecting the battery all the time. It's a long shot but won't cost you anything to check.

 

Thanks Drivesector.I will check that once I can slow down. I am down to my last 5 days in the USAF and started back to school and helping tolaunch a business..Anybody need custom T-Shirts or vinyl decals?
